So You Wanna Tune Your Hermes Lite 2.0 With Your Android Phone...? IT CAN BE DONE!!

[Marty Wittrock]

Gents,

Oddly enough, I wanted to check out the Hermes Lite 2.0 on a version of John Melton's (G0ORX) openHPSDR using a PC, but I found a version of it on my Android Note 5 phone that I completely forgot I had. So I scrambled home after work and decided to try it out to see if I could tune my Hermes Lite 2.0 with my Android. With my Hermes Lite 2.0 still connected to my router/switch (and my router/switch is attached to a Netgear Ethernet extender in my 'Geek Room'), I moved my wireless connection from the main one in the house, to the subnet (Ethernet extender) in my Geek Room. You could just as easily have an Ethernet connection to your main wireless router to your own router/switch that will connect to your Hermes Lite 2.0, too.

Once I had everything connected up, I powered the Hermes Lite 2.0, then I launched the openHPSDR app on my Android Note 5 phone. I allowed the WISDOM file to be written (it's a setup thing that the app does at the beginning) and then after that the app discovered my Hermes Lite 2.0 board and assigned it an Ethernet socket to my phone. At this point I tapped on the IP address on the screen (this turns it on) and...THE APP LAUNCHED THE TUNING INTERFACE AND I WAS TUNING 40M..!! Here is the video of me playing with the app and it all running perfectly:

https://drive.google.com/file/d/1hPQI0nwxl_grdthYw4bxRJxrcCsoq2hx/view?usp=sharing

I even took it a step further and took the phone out on my deck and for about 10 minutes tuned and listened to the 40m and 75m bands - - ALL RUNNING PERFECTLY.

So...If you don't want to be strapped to your radio room and want a little fresh air while you HF surf with your Hermes Lite 2.0, THIS IS FOR YOU..! ENJOY..!!

I just checked the Playstore twice - no openHPSDR found.  Can anyone else see it?

The openHPSDR app has to be downloaded from Amazon - John put it there instead of Play store. However, go to the Play store and pull down the Amazon Appstore app. Once you have that, search for 'openHPSDR' and then select and download it to your Android device. Launch the app and you'll be good to go.

For those following this thread, I wanted to be clear on the WiFi setup:

1.) I use a Netgear WN3000RP (or older equivalent) Wireless Ethernet Extender - this allows your main home wireless Ethernet to bridge to your own subnet. Setup of this is found with the Netgear Wireless Ethernet Extender instructions in the box and won't be covered here. It's incredibly simple to set up to bridge your main wireless router or modem.

2.) The Netgear Ethernet Extender has a RJ45 port on the side that allows you to connect to a wired router/switch - - the router/switch I use is a Netgear F5105, it's a five port router/switch. You plug an Ethernet cable between the Wireless Ethernet Extender into the first port of the 5-port wired router/switch. This allows your subnet to be extended to connect up to 4 available ports.

3.) Connect an Ethernet cable into the second port of the wired router/switch and connect the other end to your Hermes Lite 2. This now puts your Hermes Lite 2 not only into the switch for a wired connection to a host PC to control the Hermes 2, or you have wireless Ethernet available, too.

4.) If you want to control your Hermes Lite 2 using your Android phone, be sure to pull down the openHPSDR app from the AMAZON APPSTORE (not the Google Playstore). You may have to download the Amazon Appstore app onto your Android phone first and then use that Amazon Appstore app to pull down the openHPSDR app FOR FREE - - there is NO CHARGE for downloading the openHPSDR app from Amazon - - again IT'S FREE.

5.) Once you have the openHPSDR app on your phone, make sure to set up your WiFi settings on your Android phone to connect and obtain WiFi from the Netgear Ethernet Extender - DO NOT USE YOUR REGULAR WIFI CONNECTION, USE YOUR NEW SUBNET.

6.) Once you have WiFi connection to the Ethernet Extender, make sure you power your Hermes Lite 2 and then launch the openHPSDR app on your Android phone. The first thing the app will do is write the WISDOM file for your phone and the app to play well together. ALLOW IT TO DO THAT UNTIL IT'S COMPLETED THAT.

7.) At this point (once the WISDOM file has been written to your phone) you should see an IP address on the user screen and an identifier showing that it's a Hermes Lite 2 connected (with the IP address). Tap once on the IP address and this will launch the app and bring up the User Interface and also start spooling data from your Hermes 2 and you WILL hear audio. 

8.) Play away - there is nothing special about shutting down. Just close the app and the Hermes will just go into an idle state.

Have fun with it..! 73 de Marty, KN0CK

Hi Marty,

Very interesting stuff. In the past, we've had more drops with wifi than with cable connection. By using the extender subnet, are you able to reduce these drops? What bandwidth receiver are you able to run? At what point are there too many crackles and drops?

Steve,

The video shows (not real well, but I froze the video to obtain this) that the Hermes Lite 2 was viewing a 50 kHz wide spectrum on the top trace, but the app itself shows another spectrum below it of the entire tuning range (presumably 80m - 10m) in the second trace. For the time I had the Hermes 2 Lite tuning using the Android I didn't experience any pops, clicks, interruptions in the receive path. I plan to do more testing (...and that's coming next) and I will open up the spectrum of the Hermes Lite 2 and see when (or if) running the wireless Android openHPSDR app if it begins to choke on the amount of data it has to push out of the Hermes over WiFi - so I'll report that later and you'll see that on a subsequent post on this thread.

I have been asked by a colleague of mine to do a performance and transceiver comparison of three SDR that are TAPR compatible (and that I also own all of them - easy to do the comparisons):

1.) Hermes Lite 2.0

2.) Radioberry

3.) Red Pitaya

...and perform the following measurements on them using a Windows openHPSDR controller (the Android version receives fine but will not transmit with the Hermes 2 Lite because it complains about not seeing 'Penelope' or 'Pennywise'):

1.) Minimum discernible receive signal level

2.) Maximum receive signal input level

3.) Maximum usable tuned receive bandwidth

4.) Two-Tone SSB Max Power Transmit measurement

5.) Transmit Spurious

The intent of this is to give everyone a clear view of what each SDR brings to the table so they can choose what they want for most important transceiver features. Radioberry and Red Pitaya are going to be transmit limited because they do not have a 5W output level, but I'm just going to report the facts as I have them. The tests are not exhaustive (phase noise, close-in spurious, etc) - just the 'bottom line' performance characteristics to 'clear the air' for each SDR. 

I am planning - this afternoon - to do those measurements and post them here and on the SDR forum on Facebook that I subscribe to...Stay tuned...

Hi Marty,

The HL2 receivers run at 384, 192, 96 or 48 kHz, and you can have up to 4 of these receivers running simultaneously. Since you are reporting 50 kHz, are you viewing a subset of a 96 kHz receiver? There should be a selection somewhere in the software for the receiver bandwidth. I'd like to know what is the maximum receiver bandwidth and maximum number of receivers your setup is capable of before pops, click and interruptions.

I expect the radioberry and Hermes-Lite 2.0 to have very similar receive numbers as mentioned in AB4OJ's Hermes-Lite 1.0 report as the AD9866 frontend is common with similar filters to all:

http://www.ab4oj.com/test/reports.html

I am wary about boiling down radio specs to just a handful of numbers as I don't think it captures the full story or experience. You need to factor in cost per performance, as the HL2 is a budget radio with decent performance. You need to ask yourself, "would I have missed that QSO or struggled more with the QSO" because I used this radio rather than that radio. That is a hard metric to measure, and one that I don't think is reflected by traditional measurements in 95% or more of typical QSOs. Probably the biggest measured weakness of the HL2 is the receiver's perceived ability to operate in a very active HF region such as ITU region 1. But we have many happy operators in that region. A few people who live near a commercial transmitter have to add additional filtering. With the N2ADR filter board, we have a HPF filter to block AM stations, as we found this to be the largest contributor to ADC use. So be sure and try to account for a wide active HF spectrum, with lots of incidental dither but AM blocked with the N2ADR filters inline. I don't think such practical environments are captured nicely in a lab test that uses just a couple of strong signals from a signal generator. Finally, understand how the RX LNA is set and filters selected as different settings for these will make significant changes to your measurements.

Hi Steve,

I'd like to point out that the extender in this case is used as an access point (in access point mode).  If for some reason it works better in this setup than connecting the HL to Your normal wifi, that can probably be due to other reasons such as for instance:

- Many devices connected on the existing LAN and Wifi, making the number of broadcast packages eat a portion of the available wifi airtime. 

- Perhaps the extender AP uses newer wifi technology than your trusty old AP (802.11ac for instance), or perhaps uses the faster(less crowded) 5 GHz band etc which increases the available bandwidth as long as your client device also support them.

I run my HL2 over wifi here normally. 

Usually at 192khz bandwidth. My wifi setup is with Aruba AP-325 access points, 2 of them to cover the house.

Cheers,

Jonas - SM4VEY

Hi Jonas,

Good to know. I probably need to update my wifi and try again. I tend to use older inexpensive used wifi routers and run FreshTomato on them. There are a lot of other devices connected too.

Hi Marty,

Just a few more thoughts that occurred to me in the shower. IN3OTD has been active for many years on this group. He has made many good and comprehensive measurements, including sweeps of frequency and LNA gains settings. I've tried to capture his contributions here:

https://github.com/softerhardware/Hermes-Lite2/wiki/Performance-Tests

https://github.com/softerhardware/Hermes-Lite2/wiki/Community-Projects   (Link to his blog at the bottom)

This groups has been active for 5 years with various iterations of the Hermes-Lite. You can find *many* threads about performance if you dig through the past.

The radioberry forked from the Hermes-Lite project. If you are comparing with the radioberry, please keep in mind that one big difference is the bandwidth from the unit to the host computer. With the HL2 we use gigabit ethernet. This allows us to connect to powerful host pcs as well as single board computers such as the RPi that include ethernet. This enables people to have 4 simultaneous receivers at 384 kHz for skimming, radio sharing or just to monitor many bands. I'm not sure what bandwidth the radioberry is up to now, but it is something less than this. The HL2 still needs to make full use of the gigabit, and there is room to grow.

On TX, the radioberry is using the IAMP just as the early Hermes-Lite 1.0 did. We discovered a bad nonharmonic spur when using this which made it very hard to make the transmitter legal on 15M to 10M. We switched to the TxDAC and external RF preamp. This eliminates the spur and the external RF preamp is probably better. Take a look at harmonics and distortion during TX.

The radioberry and Hermes-Lite 2.0 use the same clock oscillator for the AD9866, but the HL2 uses a low jitter PLL to double the frequency while the radioberry uses an PLL internal to the AD9866 to double the frequency. I actually suggested this oscillator and AD9866 doubling to Johan as I am interested in it as a lower cost build option for the Hermes-Lite 2.0. I've always wondered if there is a difference in receiver phase noise due to this difference. It would be interesting if you could measure this. There is an early wiki page where such phase noise is discussed:

https://github.com/softerhardware/Hermes-Lite/wiki/Clock-Phase-Noise

The HL2+N2ADR filters is a complete QRP transceiver, but the radioberrry and red pitaya alone are not. This results in user experience and cost differences which should be factored in to any comparison.

With all that said, please understand that I am still big fans of the radioberry and red pitaya. The radioberry has a great price point for home brewers and perfect form factor for the raspberry pi. Many people won't care about the difference I point out above. The work done by Pavel on the red pitaya is prolific and well done. I often refer to it for ideas.

I have been working on some prototypes for dramatically lowering costs of DDC SDRs which I hope to share in a few weeks...

[ROBERT ENTWISTLE]

"Finally, understand how the RX LNA is set and filters selected as different settings for these will make significant changes to your measurements."

Thanks for this Steve. I have been wondering about/puzzled by the Dither and Random click boxes (and the RX behavior when selected or not) in piHPSDR for my Radioberry experimentation (still waiting for my HL2 or even shipment notification). Now I know why these act the way they do, it is much more than meets the eye or what I thought I could explain based on Google searches.

Looking at the AB4OJ stuff led me to: https://github.com/softerhardware/Hermes-Lite/wiki/Software#hpsdr The HPSDR section through the Step Attenuator section explains a lot with regard to the above, glad to "have a clue" about these now!

Hi Marty,

I've with Steve on this one about using caution in this. There are a very large number of factors at play like subtle competition of imd vs noise at different gain settings, possible effects of incidental dithering etc The software can have a significant effect as some do and some don't allow for the peculiarities of each radio and probably have defaults tuned to the most common radio used by the programmers.  I'm not qualified to comment on rf performance measurement and utterly deffer to the likes of  Claudio IN3OTD and Adam Farson VA7OJ/AB4OJ and have have used their measurements to hopefully optimize parts of my software. I've put quite a lot of work into allowing fair on air comparison of wspr.ft8,ft4,jt9,jt65,psk reception of open hpsdr radios in SparkSDR it might be worth having a play with this first to get each radio running at its best. At my qth I have to say a HL2 and Orion 1 board (which has far higher specs) are level pegging on spots.

Steve,

In an effort to be a good steward of the data I'm collecting on the three aforementioned SDRs, I have decided not to publish any of the results and only communicate my observations to the Ham (and this guy is just like me - an SDR tinkerer - nothing more) that originally asked for them. I realize that we're also dealing with three completely different SDRs in terms of their designs and features even though all three are supported on the openHPSDR protocol(s). I'm technically aware enough (a Principal Electrical Engineer for a very large aerospace and long-time communication company out of Cedar Rapids, Iowa) to sift through those differences and put objectivity into what I'm collecting and examining. While I'm learning the more intricate details of the HL2 and Radioberry (I'm very familiar with the Red Pitaya, and for that matter an SDR that was on the cutting room floor - the LimeSDR) it's not my intention to publicly state anything about any of these SDRs...Just to collect the data, examine the results, share it with the Ham that asked for it, and then go about casing-up my HL2 and playing with it some more.

Again, nothing will be shared on this forum given the sensitivity of the subject matter and variables of the SW and HW between the platforms.

I will tell you this - I have measured the receive sensitivity of the HL2 from 80m to 6m and I find it to be outstanding (and I have configured the filter board in the openHPSDR app so it would function in Rx and Tx per what is published on that)...But that's all I'll say on the matter... :)

73 de Marty, KN0CK

[Steve Haynal]

Hi Marty,

I don't what you to suppress or hide any data. This is an open source project, and we try to be open about everything. My feedback to you and others is just that all measurements must be taken with a grain of salt, and one must consider the full use model when evaluating any SDR. A recent evaluation by a person with your skills would be helpful. Here is an analogy that may clarify what I am saying. The Hermes-Lite 2.0 is like a Toyota Yaris, an inexpensive entry car in the US market. It does a great job of getting you to and from work, and on leisure trips. The price is low and gas mileage is good. It is very reliable and probably meets all of your transportation needs. Maybe when you are driving up some hills, a few other cars may pass you, but you still get to where you need to go. It may not have the leather interior. Although you can find cars with more horsepower, interior room and lower 0-60 times, that often doesn't matter for 99% of your use. When evaluating SDRs, people tend to fixate on a few numbers and haven't learned that like a car, the whole experience and package, and whether it meets your practical needs, must be considered.

And I am not saying this because I think the HL2 is second rate. As Alan saw with recent head-to-head digital spotting comparisons, the HL2 holds it own against radios with much better paper specs. I have seen that in the past too.

The HL2 does not support 6M but tops out at ~38 MHz. This is something you'll learn after spending more time with the radio and other documents. So please get to know the HL2 intimately and in great detail before you break out the calipers, and report on the whole experience, even trying to quantify the user experience.

[Steve Haynal]

Hi Robert,

It sounds as if the Radioberry is using the old mechanism using Dither/Random to set the LNA gain. We found that too confusing, and a user rarely benefits from setting the gain more than +20dB. With the HL2 gateware, the LNA ranges from -12dB to 20dB and matches the 32 steps of openhpsdr radios for openhpsdr software such as piHPSDR or PowerSDR. This is much more intuitive for software without native HL2 support. Quisk and Spark SDR support the full -12dB to +48dB range of the HL2. See here for more details:

To be clear, the Radioberry gain problem exists when using the Radioberry in emulator mode, now I know why.  In standalone mode (as hat to an Rpi), the problem is not there.  Thanks Steve!

Hi Steve,
You've done a great project -- decent performance at low cost. A 5W HF
all-band DDC/DUC SDR at not much cost over  a 1W Softrock covering 3
bands + a "decent" (really awful in SDR use) sound card.
Some months ago David asked me how HL2 could be produced at such a low
price when it contains more parts than his ODYSSEY-2 which does not
contain LPF's.

I've not done any performance tests but HL2 does a great job alongside
the ODY-2, HiQSDR and LimeSDR-USB,.
The LimeSDR-USB languished unused until a few days ago when I installed
an openSUSE package of John Milton's linhpsdr. Other software such as
gqrx and sdrangel were a pain and no one who said they got it working
using either application could say what they did. sdrangel reminded me
of a computer 50+ years ago that had to be programmed by flipping
switches and inserting plugs in a particular order. I was even told I
had a bad USB cable.
73 ... Sid.

Sid, 

I installed linhpsdr on my Ubuntu 18.04 Linux box and added-in all the dependencies for LimeSDR (as described on the MyriadRF site - I used the PPA method to install). Recompiled the linhpsdr app and tried it with my LimeSDR - - didn't detect. So I swapped over to the Red Pitaya (my HL2 is currently on another platform) and it detected and played fine. Did you get linhpsdr to play fine with the Lime? If so, please let me know if there are any dependencies other than what MyriadRF specifies. I'm going to play with the HL2 on linhpsdr this afternoon - I'm certain it'll work.

73 de Marty, KN0CK

[Sid Boyce]

Hi Marty,
I also tried compiling Linhpsdr from git source and couldn't see the
LimeSDR either.

John Melton is away in France this weekend and promises to update the
code when he gets back. He had promised to do it earlier in the week but
never got around to it.

Then another ham who recently switched from Ubuntu to openSUSE alerted
me to the openSUSE linhpsdr package which supports the LimeSDR.

All the packages for  myriadRF, ghpsdr3-alex, QtRadio, sdrangel, gqrx,
wspr, wsjtx, freedv, wdsp etc. are available in openSUSE so I don't have
to compile source code on x86_64 like I have to on Ubuntu ARM .

Ubuntu is most used as that's what got the adverts and hype so most
vendors of SBC's ship Ubuntu with their products.
Consequently openSUSE only supports Pi and a few other SBC's.

[Marty Wittrock]

Sid,

Many thanks for the info - much appreciated. Do you have the link to the openSUSE distro that has all those apps on it? I've tried finding it on my own but for some reason not finding it. Also does this run ARM or can it also run x86? Let me know that, too. I've attached a JPG of my Hermes Lite 2 running on Ubuntu and it's running smooth - but no discovery of the Lime. I'd like to think I can get all the radios to sync to this app - that would really help. I have HL2, Red Pitaya and Radioberry known to work on it so far.

Keep me tuned in, Sid, and many thanks again for the link for openSUSE (that I can't find... :) )

Hi Marty,
If you are not familiar with rpm on Fedora or SUSE, it can take a while
to get used to it. Ubuntu chose to use Debian as it's base and Debian
has always done things differently though they came on the scene a long
time after RedHat and SUSE.

Either the openSUSE Tumbleweed or Leap 15.0.
https://www.opensuse.org/

After install you can download the repo files from
https://download.opensuse.org/repositories/hardware:/sdr/ and store in
/etc/zypp/repos.d/
When the repo is in place
zypper ref

"zypper se soapy" will show all the soapysdr packages, "zypper se
limesuite", etc. will show all available packages.
"zypper in soapysdr0.7-module-lms7" will install
soapysdr0.7-module-lms7-19.04.0-26.1.x86_64

The zypper-aptitude package can ease that somewhat as the familiar tools
are available, so you can use "apt update/install/???"  apt-get or
aptitude -- they all call zypper under the hood.
  rpm -ql zypper-aptitude

Sid,

Many thanks for the OpenSUSE info - greatly appreciated. It's been YEARS since I've played with SUSE and Red Hat but in 2002 I was proficient with it because Ubuntu didn't exist and the only other version out there was Debian (and FreeBSD). So, yeah, looking at it now it's A LOT different to set up than Ubuntu is, but if it plays with the Lime then that will be a good way to have all four (HL2, Radioberry, Red Pitaya, and the Lime) going so I can compare them. I'll use your notes and try to stumble through it again and let you know how it went. I think I may just pull a spare SSD out of one of my drives from another machine, format it, and install openSUSE on it.

More as that happens, again, thanks for the update and all the information, Sid -

73 de Marty, KN0CK

Hi Marty,
openSUSE (SuSE/SUSE) has been always been a great distro. You can see
all the SDR packages at
https://download.opensuse.org/repositories/hardware:/sdr/openSUSE_Tumbleweed/x86_64/

It's easy to use when you become familiar and it's very stable compared
to Ubuntu where several times an unsolvable problem results in having to
reinstall -- like the catch 22 situation where you are used to use "sudo
dpkg –configure -a" which always take you back to repeating the same
"sudo dpkg –configure -a" forever.

With sometimes thousands of updates daily openSUSE never messes up.

Command equivalents:-

apt update == zypper update
apt install  == zypper in
apt-cache search == zypper se
apt info   == zypper info
apt upgrade ==  zypper up -t package
 apt-get --reinstall  == zypper install -f
apt autoremove  ----- automatically happens. Use "purge-kernels" remove
old unused kernels.

One other tip -- when you install from DVD it asks if you need the DVD
as a repository, say No as all the latest software is available and
uptodate in the online repos.

I was asked recently about dual-boot. I have never used it, preferring
to use VirtualBox or KVM instead so i can run any OS on the current
openSUSE desktop.

Having a registered copy of Windows 10 - you can't go out and buy a
laptop without Windows.
I downloaded Win10_1803_English_x64.iso and installed it in VirtualBox
... MS reckons I am a customer so it allowed me.
I just wanted to test SDR Console and openHPSDR Thetis - both run fine.
73 ... Sid.
