THETIS & HL2 working, RX & TX

[Jean-Michel Cohen]

Hi all,

with a little perseverance I ended up (with Youcef, an OM friend) making the HL2 transmit with THETIS

You need to select APOLLO in the Hardware TAB, then in the APOLLO tab check filters & tuner

You should then be all set

My next problem to solve will be the activation of PURESIGNAL. 

So far, when I try to play with it. I start to get very frequent "check your antenna" error messages. I recommend exporting your working setting into a specific database because THETIS will never stop popping those messages...

Hi Jean-Michel,

I think Thetis protocol 1 support is very new and with limited HL2 support. It is good you have it sort of working. Reid Gi8TME/Mi0BOT is working on improving Thetis protocol 1 support for the HL2. There is another recent thread in this group about that.

I can't remember if you are new to the HL2, but since there are several new people, software proven to work with the HL2 is listed on the wiki:

Hi Jean-Michel

Thetis has been working seamlessly with my HL2 - it’s great to be able to use the same software with both the HL2 and my P2 Anan radio.  If you haven’t seen it already, watch Steve’s setup video for the HL2 in PowerSDR.  It is close enough Thetis.  It mentions turning off SWR protection which I guess is why you are seeing the ‘check Antenna messages’.

https://youtu.be/97UZi8qYAKM

PureSignal also works well in Thetis. For PureSignal I think you will need to change the SetPk value in the Advanced PS setup to around 0.23.  The default values in the main releases of PowerSDR/Thetis don’t work for the HL2.  From memory this is in in Linearity > Advanced View.

Hi Guys,

You succeeded in using Thetis with HL2.

This morning I tried to run Thetis v2.8.11. The Setup >General of Thetis indicated rightly the IP address of HL2.

However, LED of HL2 remained in the idle mode, Thetis doesn't respond.

FYI, this Thetis v2.8.11 works fine with Red Pitaya in protocol1, of course, Puresignal functions very well.

My HL2's gateware has been updated to 71p3, that I confirmed by SparkSDR after programming and power cycle.

It is very much appreciated if you let me know the setup of Thetis as well as HL2 in order to make run Thetis with HL2.

Thank you in advance.

Hi All,

I could connect HL2 to Thetis v2.8.8-x64. The gateware version is always 71p3.

Thetis v2.8.11-x64, as I mentioned in a previous mail, works great with Red Pitaya HPSDR transceiver. However it doesn't with HL2.

As the summary:

With HL2(71p3),

Thetis-x64 v2.8.8 ; OK,

PowerSDRmRX 3.4.9 ; OK,

Red Pitaya HPSDR transceiver ; OK,

Thetis-x64 v2.8.11 ; NG.

Any comments on that?

Does anyone have the steps to compile and install Thetis using a pair of HL2's such that recieve is done on one radio and transmit on the second HL2.

This would allow one HL2 to run with 10 receivers for receive on one IP address and other to transmit with a gateware that allows transmit using a second IP.

That would conceivably make the 2 unit configuration a FT8 mean machine to use for making contacts.

I've been running 2.8.11-x64 with 71p3 since Saturday morning. Worked
fine during CQ WW including using PS.

Upgraded from 2.8.6

Working fine for me with both my HL2's.

Hi Duncan,

Your message encouraged me to reinstall Thetis-x64-2.8.11.

At the rate of 192Kbps, Thetis works with HL2-71p3.

I don’t know why the previous Thetis-x64-2.8.11 didn't work with HL2 until this morning. However the previous Thetis has worked fine with Red Pitaya.

The current result is the reality. Maybe something was wrong.

Thank you again for your message.

Hi group,

I can also confirm that both Thetis 2.8.8 and  2.8.11 are working OK with my HL2. The only thing that has failed is signal averaging in the panadapter view. Neither the AVG button in the GUI nor the setup screen seem to have any effect. It is a little bit too slow for my taste ... No real problem, though.

P.S. Maybe Reid can tackle this item also when adapting the Thetis SW with HL2  in the future !

[tok...@gmail.com]

Hi Heikki,

I also confirmed Thetis 2.8.11 and PowerSDRmRX 3.4.9 with HL2(71p3) as for Pure Signal.

The combination of PowerSDR and HL2 is good. However, that of Thetis 2.8.11 and HL2 has a problem when using PureSignal here.

This problem is a fast relay clicking of HL2 when Thetis is going to stand by. When TUN is used, of course without PureSignal, this clicking doesn't happen.

Do you have this kind of phenomenon there?

They should be the same as PowerSDR for the Ham bands but there are more
options for SWL'ing which I have seen anybody post about.

Hello everyone,

Long time lurker and first time poster....

This is my following observations regarding setting up Thetis with HL2:

On the YouTube video <Hermes Lite 2 0 PowerSDR Setup> it was missing the necessity of selecting the <J16 Transmit Pins> 

If you neglect to select the <J16 Transmit Pins> you will bypass the N2ADR filter board on Tx and will transmit lots of Harmonics.

I did some quick measurements a few days ago.

Please see the attached pictures

The HL2 was transmitting full power (5.2 Watts) at 7.141 MHz (40 meters band)

The spectrum analyzer starts at 1Mhz and ends at 50Mhz - (49 MHz span)

Picture 1 --> screenshot of the YouTube video settings 

Picture 2 --> Harmonics without selecting the <J16 Transmit Pins>

Picture 3 --> My <J16 Transmit Pins> setup

Picture 4 --> Very clean Tx with the <J16 Transmit Pin> setup from picture 3

Congratulations to Steve, James and open source community  for this amazing project. It is a game changer in my station.

Regards,

K1PLL  - Luis !!

I can confirm this.

The J16 Transmit pins need selecting for both PowerSDR and Thetis for
the filter board to be active on Tx.

Just looked at spectrum analyser tonight.

[Duncan Clark]

Jim shows the settings here for J16:

http://james.ahlstrom.name/hl2filter/

Note: Band 7 the HPF is ticked both on Tx and Rx.

If you don't tick 7 on Tx I think you will hear the B7 relay switch upon
going back to RX from Tx i.e. two relay changes (K2 on the HL2 board and
B7 on the N2ADR board) one after the other. Rx to Tx they change at the
same time. At least I assume it is that :-)

Hi All,

In addition to General>Hermes Ctrl, IF you would like to test PureSignal with Thetis v2.8.11, a value SetPK in Linearity>Advanced should be “ 0.230 “.

This SetPK value is a default of piHPSDR for HL2 Pure Signal setup (See below). About this value, Christoph, DL1YCK wrote in his « PURESIGNAL for HermsLITE2 .  

In Thetis, you have to change SetPk to this value each time as Thetis started.

Thought it may not be necessary to mention above. But hope that this would help for those who have just started to use HL2 with Thetis.

Hi Luis,

Congratulations on your HL2 build. Yes, the filters definitely need to be set for TX. I thought there was some setting which said to use the RX settings for TX. For TX, the HPF will be disengaged during TX via hardware to protect the HPF so that setting doesn't matter.

Hi group,

After just following the conversation here, the Thetis AVG button for panadapter started to work with no contribution to the SW/HW from my side. hihi !

FYI: I have not started with PureSignal yet ...

Hi Group,

This is a screenshot of Pure Signal at 100W by Thetis v2.8.11 with HL2(71p3).

HL2 is connected to 100W amplifier through RF1 of HL2.

Thetis is unstable when PTT keyed and released.

In what way?

What happens?

[tok...@gmail.com]

Hi Duncan,

My test environment:

Thetis-x64 v2.8.11 with HL2(71p3). RF1 out of HL2 is used to drive my 100W linear amplifer via some attenuation.

Issue:

The transition from RX/TX causes heavy click noise from RX and heavy chattering of TR relay.

This problem is observed not only for Puresignal but also for TUN/CW.

Some time the panadapter shows a "broken" spectrum(see attached picture).

Observation:

I've done an intensive test Thetis-x64 v2.8.11 with Red Pitaya's HPSDR transceiver of Pavel Demin as to Puresignal, TUN, and CW.

Nothing happened such phenomena. Of course not with Orion MKII of Apatche Labs nor Hermes of TAPR.

As I reported to the group, PowerSDRmRX PS v3.4.9 has no problem with HL2(71p3).

If you do not have the above problem for the combination of Thetis and HL2, I'm very much interested in hearing what the firmware(gateware) of HL2 as well as Thetis version are.

I see the noise but I don't get heavy chattering. I do hear two relays
changing. The quietest relay, presumably the HPF, switches with variable
time delay and that I cannot explain. It can seem like a long delay but
is probably only a few hundred msecs

I also see a large burst of noise going from Tx to Rx with a . I see
similar on PSDR but a smaller burst of noise

>This problem is observed not only for Puresignal but also for TUN/CW.

Not tried CW but definitely occurs with TUN and DUPLEX, with or without
PureSignal active.

>Some time the panadapter shows a "broken" spectrum(see attached
>picture).

Agreed but I only see the broken spectrum every so often, not every Tx.
It's very random

I do not see this with PSDR.

It occurs whether I use gateware 70p4 or 71p3, on both my HL2's.

[tok...@gmail.com]

Hi Duncan,

Thank you very much for your testing.

Although there is some difference of observation between your test and mine, the problem is shared.

But this is bad news. To be honest with you, I expected a possible solution to use Thetis and HL2, since this post started as a hope of this usage.

I  started to use the latest version of SDR Console of Simon with HL2. This SDR application is AMAZING for RX. But I have some problem for TX. For example. TX gain setting linearity is not the one I expected. This is the same for PowerSDRmRX v3.4.9.

I hope the builders concerned would help the users even though this is a voluntary basis. Anyway, as a whole this is a hobby.

Hi Tokio-san,

Thetis was only just released with support for Protocol 1 a few months
ago. Also the team developing it are not on this list and have very
little knowledge of the workings of the HL2, they are more concerned
with the Anan range of transceivers. I have been making updates to
PowerSDR for HL2 and have turned my attention to Thetis as well.

At this stage, I would advise you to try the Beta 7 of PowerSDR which I
think you have access to. It has extra controls to control the latency
buffer and other features, so should help with network issues.

If there are specific requirements that people work like to see, bring
them up and we can see how much demand there is for a particular
feature. The more popular, the higher up the list.

Cheers

Hi Reid-san,

Thank you for the clarification about the issue concerning a catch up for Thetis update.

Yes, I use your PowerSDR v3.5.0 beta 7 with HL2, and I also noticed PA Enbale/Disable menu. I appreciate very much your effort to adapt PowerSDR into HL2.

Here in Japan, now there is a growing number of  HL2 users, and on the air, amateur radio operators are asking to me how HL2 is working. As to SDR, they are accustomed to use PowerSDR(and they are going to use Thetis due to its protocol 1 capability), because of the popularity of Red Pitaya SDR software. So they are expecting to use PowerSDR/Thetis on HL2 too.

I’ll use further your SDR software, and let you know the eventual request of the functionality.

In Thetis v2.8.11, there is a setup panel as attached.

Please look at Setup menu:General > Alex.

Isn't the function you want?

However, I didn't confirm this with HL2.

Hi all,

I just tried Thetis on an old prototype HL1 (not the HL2), and when pushing on TUN or Mox, I get a "High SWR condition detected" message & "please check your antenna connection" and TX stops. Probably because this release waits for SWR data from a HL2.

I have found the same option, located in the "alex" page (the reason why I deleted my posts), so the issue is solved, and Thetys works also with the HL1 .
