Release of Thetis v2.9.0.8-HL2 Beta 5

[scumballc...@gmail.com]

Hi,

This is the release of v2.9.0.8-HL2 Beta 5 of Thetis for HL2.

https://github.com/mi0bot/OpenHPSDR-Thetis/releases/tag/v.2.9.0.8-beta5

- Added ability to access HL2 over a WAN connection.

You can now connect to one or more HL2s over a WAN connect. This has been tested with direct port access but should work over a VPN. WARNING, direct port access could open your network to hacking.

When selecting Static IP,  there is a second option which needs to be unchecked to take the local subnet limitation off. This will widen the seach for a HL2. You can also set the port so that more than one HL2 can be accessed. Please read up on NAT and port forwarding. There is a check box below the IP address to allow the currently connected device's IP and port number to be displayed on the title bar.

Sample rate should be set at 48K. I have been able to have RX1 and RX2 running at the same time on different bands. You can also use MultiRX to get another receive on VFO A.

Very limited test transmission have been make but don't expect PS. You should set your hardware TX Latency to 70 msec and hardware PTT to 30 msec. Both settings are in the F/W Set form under Hermes Lite Options.

I would like to thank Pez for openning up his network and allowing me access to his network of two HL2 and help test. It's pretty cool to sit and listen to two different band in Oz sitting in Northern Ireland. You can't get much further for testing the system.

It isn't a proper install but a zip of an install and can be placed in an different directory (I use C:\OpenHPSDR) so should allow the original release to still be used. Then just run Thetis.exe within your new directory.

If you haven't already done so, you first need to install the latest release of Thetis (x86 or x64 version) as it sets up things like skins and support for the new meter functionality. The link is

https://github.com/ramdor/Thetis-2.8.0

Please read the release instructions associated with the above release as there has been updates to resources which will affect some controls.

This release may require a reset of the database.

No warranty or guarantee, use at your own risk. It should use it's own database but do a backup of your current Thetis one just in case.

Cheers

Reid, thanks for the latest update, looking forward to testing it.

Phil

[Pez]

Thanks Reid,

My remote HL2 connection's have been up for a few hours at 48kHz, with no dropouts or disconnects seen on the RX at all. It is working great! :)
All settings are as per your recommendations: 48kHz sample rate, TX Latency to 70 msec and hardware PTT to 30 msec.

Remote TX is also working, but I need to test this further to see how the HL2 TX buffer is keeping up. So far so good in my quick TX tests today.

I greatly appreciate the work you have done here, and I look forward to hearing how other remote HL2 users go with Beta 5 as well.

[Pez]

Hello all, 

Here is a picture of Thetis HL2 Beta 5 working remotely over WAN to my HL2 today. At this PC end, I was connected via WiFi as well. I had a few quick QSO's on 40m and I got 5x9 reports. This is a LOT of fun, and it is all performing better than I expected. (YMMV of course!) :)

[Toonces Cat]

Hello Group,

 A brief description on how to set up  the server and client side would be much appreciated.

 I assume that...

1. The HL2 must be connected to your router ( not directly to your computer ) On the server side.  and does Thetis need to be running?

2 . The correct port must be open on the server router.

3. Thetis on the client side must point to the WAN address/port .

I have run many different remotes over the years like Remote hams (rc Forbs) and recently SDR control and a IC-705 so opening ports etc. is no trouble.

Thanks for the information,

73's

Yes, HL2 must be connect to router and no, Thetis does not need to be running on the server (HL2) site.

2 . The correct port must be open on the server router.

The port can be specified but 1024 would be the default. That port must be routed to the HL2 on the server site.

3. Thetis on the client side must point to the WAN address/port .

Yes, the use static IP check box must be checked and the limit to subnet checkbox must be unchecked. NB, the limit to subnet checkbox will automaticity check itself if the use static IP checkbox is unchecked.

The IP address of the remote HL2 must be entered in the table, the radio checkbox selected for that IP address and the select IP button pressed.

I have run many different remotes over the years like Remote hams (rc Forbs) and recently SDR control and a IC-705 so opening ports etc. is no trouble.

I'll be interest in your results.

Reid,

 Thank you so much for this information. I have  a few more questions and my remote setup is 1 hour away and I have to drive there to hook this up.

1. Will the HL2 receive an IP address from my router (DHCP)? I have always connected the HL 2 directly to a computer with my cat cable.

2. Will this work with a Anan type radio as well? I have a 10E as well as a HL2? (for future reference).

Thank you.

Yes, but you may have to create a static DHCP entry to ensure the HL2 gets the same IP address each time. This is important because you have to setup a firewall rule to forward the externally exposed port to port 1024 of the HL2 assigned address. If the DHCP assigns a different address, after a reboot, then the firewall rule wouldn't work.

It might be better to make a completely random number above 1024 and below 65536 for the internet exposed port. Thetis can be set to work with any port in that range. This might give a bit of security.

Now there is a big WARNING here. You are exposing your HL2 to the internet without any security. It might be better if you can setup a VPN, so there is a secure tunnel to the HL2.

2. Will this work with a Anan type radio as well? I have a 10E as well as a HL2? (for future reference).

This is only in my modified Thetis. It may be adopted by the official Thetis team but I would hold your breath.

It is possible to setup your own VNP if your router supports it and not have to use a commercial product. YMMV.

Testing Thetis HL2 B5 shows some early promise.

I setup a laptop with Thetis HL2 B5 and opened port 1024 on my home router and pointed it to my HL2, fired up Thetis HL2 B5 on the laptop and pointed Thetis HL2 B5  to my public IP address and port 1024.

I noticed I needed to shut down Thetis HL2 B5, wait a few seconds and restart Thetis HL2 B5 before it would connect - is that expected behaviour?!

It now connects to my HL2 over the internet using wifi on the laptop - performance is not too shoddy but I notice a few stutters on Rx and semi regular overflows and underflows on VAC1.

Not tried Tx as yet.

I then put my HL2 on a seperate internal network behind a small GL.inet router with Wireguard VPN server on it, so the HL2 is segregated from the main home network and a different local IP range.

Setup my home router with a port forward to the internal Wireguard VPN router.

Added the Windows Wireguard VPN client software to my laptop and imported the Wireguard server client connect configuration.

Tethered my smart phone to the laptop for wifi/internet connection with only 1 bar of 4G signal.

Added a new IP configuration in Thetis HL2 B5 to match the Wireguard VPN (actually the HL2 IP address from the GL.inet router LAN config), closed Thetis HL2 B5 and restarted it after a few seconds.

Thetis HL2 B5 now connects to my HL2 over the internet via a VPN.

Performance is similar to the above 'direct' connection, but again not too shoddy for a first test.

The good thing with a VPN connect is it is more secure than a straight port forward on the main router.

A static/fixed public IP address is a must for the Wireguard VPN and I'm lucky to have a static public IP address.

More testing required and for sure a better internet connection is going to help a lot.

On a side note, I have also tested the Quisk remote solution, and on the same connections as above, Quisk is very much better at holding the connection without stuttering on Rx or Tx and it runs at 192kHz no problem.

I have used Quisk remote on Tx and the contacts I've made had no idea I was remote over a smart phone tethered to my laptop.

[Pez]

Hi Nigel, 

Good stuff. FYI, the Quisk remote solution is a true server/client solution that manages all of the transcoding and compression/buffering, which is why it works so well remotely... If only I could get used to the old school Quisk Python interface and graphics / UI... I just can't unfortunately! I became spoilt with the Thetis and SDR Console slick UI ;) 

In the case of Thetis Beta 5 (and other software such as the SDR console latest beta, Spark SDR, etc) that also support this "direct UDP" connection option, they are connecting "natively and directly" across the network without any client/server smarts like buffering or compression, so the results are not as stable as you see in Quisk (especially at higher sample rates!). 

But despite the caveats on direct UDP across the WAN or VPN, Thetis Beta 5 is proving to be very workable for me at 48kHz, and it is a lot of fun. It is fantastic that we now have these options available in Thetis. My hope is that it opens the door a little further to more development and clever new solutions for remoting. 

My remote RX performance has been perfect. I have seen the occasional TX stutter, but nothing QSO ending so far. 

73

[G4ZAL]

Hi Pez,

Agree on Quisk remote and it is definitely working great over a poor connection.  I don't mind it's 'old skool' look.

If Thetis HL2 could work in a similar server/client relationship, it'd be a winner for sure.

As it stands, Thetis etc are 'bandwidth hungry' and don't work as well over a poor link.

Reid is making great stides with Thetis HL2 and hopefully will make it better still - my grateful thanks to Reid.

BTW Pez, what is the rinky dinky little 'Pocket PC' you used when remote in your pic above ?

I have the same wireless keyboard/touchpad and similar headset (mine is Jabra Evolve).

Nigel

G4ZAL

[Pez]

Hi Nigel - I couldn't agree more! :)

The little PC is a HiGole1 Pro (or a Gole1 Pro). It is fully self contained Win11 Pro box (built-in battery, touchscreen, ethernet, WiFi, BT, etc) and has really good I/O. It runs warm to hot if you get the processor really working, but for Thetis and SDRC I have found it good. It's surprisingly fast too. It comes with licenced Windows 11 Pro - BUT it also comes with a virus pre-installed (crazy, but true.) If you get one (Amazon or Ali Express) I would highly recommend doing a backup up of the drivers as they are not easy to find online, then wiping the OS and installing a fresh and clean copy of Windows - I am using "Tiny11" (Google that) and it has been perfect for the job! The Win11 digital licence is valid so it's fully operational for Windows updates if you need it. 

The headset is an Avantree Alto Solo - it's great value for the money (the USB Dongle version is best, as it also includes BT if you want it. But the USB Dongle connection is WAY better than BT for radio work, because in Windows it simply appears as a plug-and-play USB Soundcard, and not as a fussy or laggy BT audio device!). I also have a Jabra Evolve 2 65 at work which I love, and while the Jabra is best, the Avantree is perfect for this job and was 1/5 the price!. 

73

[Toonces Cat]

Reid,

 I have The remote going with the suggested settings and I am getting received audio fine at the client side however, TX is very "chattery". My download speed at the HL2 side is 200+ down and only 10-12 up and on the client side (fios)  50 up and 50 down. Both sides are hard wired to the routers (not wifi) and the HL2 is running about a watt to rule out RF. 

 I am wondering if maybe my internet speed isn't fast enough?

Thank you.

[Pez]

Hi Mike,

Keep in mind this is an experimental feature and is not always going to work perfectly for everyone. I would say your issue is a lot less about the speed/bandwidth of your connection (mine is similar to yours), but is more to do with network jitter, latency and/or UDP packet loss across the networks. The HL2 is fussy with this, and it is the nature of UDP to cause these types of issues when something is not perfect. The router hardware at both ends can play a big part in achieving a good connection too (things like cheaper domestic ISP supplied routers can contribute to poor UDP performance). Also, Ethernet cable is always better than WiFi, but I see you have ruled that out. 

I assume you are running at 48kHz with PS OFF? Also, have you set both your hardware TX Latency to 70 msec, and hardware PTT to 30 msec? Both settings are in the F/W Set form under Hermes Lite Options. This was the most important step for my setup. 

73

[Toonces Cat]

Pez,

  Thank you . All the setting where correct except PS OFF . When I turned that off the next morning the TX audio is smooth and working.

 Sorry for that oversite. I had loaded in a profile that used PS.

[Pez]

Hi Mike, that's fantastic. Have fun! FYI, There is some investigation happening to see if the bandwidth required by Thetis can be reduced further for remoting, so it's exciting times. :)

Hello , as you said Pez , this release is providing some significant features for remote purpose. I am planning to test the Network and IP features during the Week-end. 

So far i am using the Thetis v2.9.0.8-HL2 Beta 5 releases for 3 days now (SSB and CW) . All working good therefore i just notice for SSB mode , the AF level is moving a lot on the VOX level field , making a bit tedious to adjust . I just scratching my head to figure out where i maybe failed to adjust correctly some levels . Otherwise this release is really great and cannot wait to test the new network and IP features.

73s  Didier

[Phil]

A question on the IP addressing , if the HL2 has a static IP address set, how does it know the gateway or doesn't it need that information?

[Jonathan Jesse]

Thank you, Reid for this update.  The networking was easy and it is slick!  No Fuss-No Muss.  I've only tested the receive because I'm still playing with it.  I see no reason that transmit will disappoint.
Thanks again and 73,

Hi Reid,

Please forgive me, I'm not sure about installing your zip of thetis. I recently got my HL2 and have used it with powersdr, hardware seems to be serviceable.

I downloaded and installed the latest version of mw0lge thetis v 2.9.0.8 and it went to the default location in my C drive, then without running it I installed your zip of thetis to the suggested C drive location. I'm not sure what to do next, I have unzipped the folder to the same place. Do I create a shortcut of the exe file of your thetis to the desktop?

As you can tell, this stuff doesn't come naturally to me.

[V85NPV]

Hello guys ,

Did some WAN remote tests last night and was pretty pretty much very straight forward. i applied Reid recommendations regarding TX and PTT Latency to apply. My Hermes lite is connected not directly to my internet access but throught a WIFI bridge . For testing purpose i open all Internet router ports and did not apply any NAT setup. 

i open THETIS in admin mode, 48000 for sample rate , setup in the static IP address field with the public internet address, enable Static IP and un-tick limit to subnet.  The remote computer was able to connect the Hermes Lite without any issue. i just perform some basic TX test and did not notice any IP drops. No particular drops also during RX

Many Thanks Reid for this release , this is really a step forward regarding the HERMES LITE features.

That's about it. You only have to install the official v.2.9.0.8 to get the skins. Just create your short cut and run Thetis from it. Best to make the "Start in" directory in the short cut point to the directory you uniped the release into.

You should find basic setup information at https://github.com/softerhardware/Hermes-Lite2/wiki/Thetis-Setup but that is from a few releases ago. Maybe you could detail what's different and I can update the Wiki.

I just usually find the unzipped thetis.exe in the expanded folder, bring up the properties and select "add to taskbar" When a new version comes out, just remove the taskbar thetis and add the new one the same way.

[Pez]

Hi Phil, 
 
You need to have a read up on NAT and Port Forwarding. This is what enables your LAN router/gateway to direct the required UDP packets to and from your HL2 - in and out of your LAN to the WAN, on the UDP ports you require.

The first step is giving the HL2 a static IP (or a static DHCP entry in your router/gateway). Then you should be able to setup the NAT and Port Forwarding rules in the router/gateway that are needed. 

NOTE: As long as your WAN IP address is public (not behind a "CGNAT"), and your ISP hasn't blocked any ports (some do), and you can access your router/gateway NAT and Port Forwarding settings, then remoting the HL2 should be possible. 

73

[Phil]

Perrin, I’m OK with Nat and port forwarding, working with PABX’s and VOIP telephony, Lan gateway addresses were always necessary.  I regularly use remote with my 590SG.  I don’t have a static public IP but I have a dynamic DNS setup so I can easily lookup my public IP.  Looking forward to testing the remote operation.

[Pez]

Sorry Phil, I misread your post as though you needed some assistance with that. OK, very good! The HL2 doesn't need to be told about the gateway IP. Just using a static DHCP or setting a static IP in the HL2 gateware should have you on your way with normal NAT and port forwarding. (FYI, you can use Spark SDR or Quisk to set the static IP and custom MAC if needed). Good luck and have fun!

73

[Ian Watson]

Thanks Reid, I have given that a go, the only thing I'm not quite matching up is the Setup | PA settings. When I click 'reset to defaults' I expect to see 38.8 dB on all bands, but I am seeing 100 dB from top band to 10m, 6m (not applicable I know) is at 38.8 dB. I can manually set 39 dB, is that correct?

Some of the settings not mentioned are different to those on the link you sent, but they aren't mentioned in the wiki.

73,

Ian MM0GYX

[Pez]

Hi Ian,

The PA Settings in Reid's latest HL2 Beta versions (since Beta 4) have been changed to read as a %. So "100" is now 100%. 

At around 39% (which it will be the default after updating from a previous version), you will only see around 2 watts output. Change these values to 100% and everything will be back to full power. I hope that helps.

73

[Ian Watson]

Hi Pez,

Nice to hear from you; that helps, thanks. I set to defaults and tested into a little dummy load. The software power meter says 6.8 watts, my dummy load rectifier says 6.9 watts, so they agree very nicely. Presumably I need to wind back that 100% default on a band by band basis to achieve 5 watts, right?

One other thing, when in 'tune' there's a relay click at the start and end, as expected, but during the period of tune there is an occasional click, seems like a glitch, any thoughts?

73,

Ian MM0GYX

[DL1YCF]

This is dangerous, since if 100 percent translates to 39 dB, it will overdrive the PA.

In my HL2, I must adjust to about 40.5 dB for full power output, which is 6 watts
without N2ADR board, and 5 watts if the TX filters are engaged.

[Pez]

Hi Ian,

Yes, I would set for 5 watts, or lower if that's what you need. Regarding your occasional relay click 'glitch', that sounds like it could be a network jitter/latency issue. A couple of things:
- WiFi is less reliable than Ethernet cable. 

- Is your PC/CPU or network doing something else at the time? 

- Have you set the the TX Latency and PTT Hang times in Thetis (Setup / General / F/W Set)? Increasing these values might help. TX Latency = 40ms and  and PTT Hang = 20ms is often recommended, but I have some installations set at the maximum values of TX Latency = 70ms and PTT Hang = 30ms for the best results. 

@DL1YCF this is a good point - Have we seen any hardware failures as a result of overdriving? Or is it more a case of the IMD and spectral purity suffering? If there is a risk of damage then we should definitely communicate this. Initially it was mentioned somewhere in the group to set them to 100%. Hopefully Reid can comment on his implementation of this setting?

I assume the new 100% = the old 38.8. But Ried can hopefully confirm this.

[Reid Campbell]

The 100% relates to the maximum power of the HL2 which is nominally 5W
but the new versions might be up to 7W with the new transistor type.
This control is a hark back to the Hermes or the other single boards
that didn't have their own PA. The 38.8 was the dB gain of the external
PA. If your PA had 40 dB of gain, then the driver board needed to lower
it's power, so a higher number meant less power from the HL2.

I changed this to be 0 - 100 as it made more sense, especially as new
HL2 owners come on board.

Hello Reid,

  I am impressed with the remote TX/RX audio. I am using This remote about 50 miles away from my home. The internet at the one HL2 side is cable and the client side is Fios.

I have also tried "MultiRX" within the 40 meter band... and that worked well.

 Tx audio is exceptional and the other station said "he would have no indication I was remote". 

 I do understand that the bandwidth on the water fall is small and slow. Is there any settings to speed up the waterfall/spectrum visually? I can deal with the small bandwidth

Thank you!

Hi Mike,

You can indeed! This slider should do what you need. :)

Pez,

Thank you. Yes much better than watching the "lava lamp" or "paint drying" LOL!

Reid,

  I really like how this is working and sounding. Great work!!

One question that I am wondering is... will this work with a Anan 200D or a 10E running protocol 1? I think your software can be setup to run those radios too?

I can not see any reason this will not work unless it is some kind of firmware tweak?

Thank you again!

Hi Mike,

You can try it, especially with the 10E, as it only starts 2 receivers. A lot to the time I put guards around my changes, so that they only apply the HL2 but I think these were let go as general changes. YMMV

Does the latest version of Thetis with built-in HL2 support build and run on a Raspberry Pi 4?

Thanks and 73, Ron, n6ywu

Ron,

I seriously doubt it. There are a few lucky people have Thetis working with Wine but thats is a struggle.

I was trying in Linux on a i7 with VirtualBox and it was just pain after pain , I was spending more time trying to get it to work than actually using the radio. I gave up, bought a Windows only i5 on FB for $40 and moved on. If I was having problems on a i7, you would be just wasting time on a Pi.

Hello Group,

 I have been using the HL2 remotely now with the "beta 5" and it has worked well. Does anyone know of a Android program that might work with the HL2 like the "beta 5"?

I also wish for more Android HL2 support! As far as I know, so far there is only:

• SDRpp BROWN: https://sdrpp-brown.san.systems/     - This is awesome for remote HL2 RX. I am using the SDRpp SERVER but you can go native IP direct connection to the HL2 as well. It's a really good program IMO. There is also basic (experimental) TX support for HL2 direct IP connections. 
  
  
• MagicSDR: (from the Play Store) has experimental HL2 RX support - but it appears to work with local UDP broadcast discovery only. And is limited in functionality. 

And I will mention SparkSDR: The developer has an un-released Android version he was testing. He said that the codebase was recently updated to support being compiled on Android. He has said that he "might" release a full Android version of SparkSDR "soon". That would be awesome!

That is all I know of at this point. If anyone can add more to this list, please let us all know.

Pez,

I just tried MagicSDR and it found my HL2 on my networked and receives fine. I will try SDR++Brown as I have it loaded as well... I think you can transmit with it as well.

Thanks!

No problems Mike.

Yes, regarding SDR++Brown, There is also basic (experimental) TX support for HL2 direct IP connections. I had trouble with TX relay clicks when I tried it. I have emailed the developer to ask about PTT Buffer and PTT Hang settings that might help with that.

SDR++Brown can take some setting up, but when its done it is very slick. Be sure to look at the plugins - there are built-in FT8/FT4 decoders (if that's your thing) and lots of other clever things.

Pez,

  I can not seem to find how to get it to TX screen. I seen a video of how to get to the TX screen however, I can not find it.

Thank you!

Hi Mike.

Make sure you are running the SDR++BROWN version, as the standard SDR++ does not support this feature. 

[Toonces Cat]

Yes. I have the "Brown" edition.

Thank you!

I just received information that SDR console now has the remote feature.

 see the new Beta just released. Build 3077:
