WSJTX > Hermes Lite 2

[George Pap]

Hello all. Waiting for the HL2 to arrive, doing some reading but i cant clearly understand the following.

1. Digital modes. WSJTX / MMTTY (RTTY) 

Is there any tutorial , guide on how to setup HL2 for RTTY and FT8/4 ?

2. CW operation

Can i plug my Bencher Paddle to the front right KEY/PTT port and operate CW? Or do i need some other config?

Thank you in advance, 73 de SY9DOK

As far as I know, there is no tutorial, and the actual process depends on the software you use and the operating system you are running. I can provide a description of what I am doing with SparkSDR on macOS. 

The key connector is only for a straight key, so to use a paddle, you would need a keyer. Because the side tone from the software is delayed, you would need a keyer with its own tone generator. There is a keyer project based on a Teensy microcontroller. I’ve been waiting for an update on the state of the PCB, but have not seen anything lately.

Thanks Karl! 

Both PC and Mac are available but from reading i see Thetis being the most efficient app. (still researching) 

As for the keyer i get it. I already have a keyer handy (MX-K2)to use my paddle on my old trusty Kenwood 940s that also lucks keyer. I guess it will do the job.

Hi George,

Steve made some nice youtube videos on how to setup quisk and wsjtx on linux for use with Hermes Lire 2.  I used them and they worked well for me.

Steve’s youtube channel -https://youtube.com/channel/UCFSpFFTQ5ifCZ_hXDOxkVsg

You can build and maybe buy an arduino based K3NG keyer for use with it.

Some groups keyer discussions -

Quisk on Linux was an easy way to get started.

Regards,

Well, most has been said.

WSJTX and digimodes: this has nothing to do with the HL2, this
depends on the SDR program you are using (and does not depend on
the radio).

CW: The easieast setup is an external keyer with some small
sidetone buzzer. If you want to get the sidetone on the headphone,
you can use a simple circuit and get the sidetone from the keyer
(e.g. via an AF transformer) or you use a fancy setup (Teensy4
based).

But my advice is to start with a simple keyer with integrated
buzzer.

George, 

as I said, I am using SparkSDR on the Mac. At the end, it should not matter which application you use, you do need a way to connect the audio output of your SDR application with the audio input of e.g. WSJT-X and vice versa. I am using commercial software to do that: https://rogueamoeba.com/loopback/ There is a free solution out there, but I have no idea how it works with modern version of macOS: https://github.com/mattingalls/Soundflower

Loopback installs a kernel extension that is responsible for actually routing the audio, and a user interface in which you create and manage your connections. Once created, they should show up in your applications, and you can then use the Loopback user interface to set the audio levels to appropriate values. 

The same is true for the PC, and you use "Virtual Audio Cables", but because this is not what I am using, I'll leave this to somebody else to explain. I do know that there are (at least) two different solutions out there.

(This post is about MacOS and digi modes)

I support this view. While I am using piHPSDR on the Mac, my preferred audio routing
is also "Loopback" from RogueAmoeba (abt. 100 bucks). I also have a virtual audio cable
as a system extension, I have no problems with making the source code public so that
one can compile it using XCode, the problem is that recent version of MacOS do not load
these "kernel extensions" if they are not properly code-signed which I cannot do.
If you compile yourself, the resulting kernel extension is accepted by MacOS, but I
cannot distribute working precompiled virtual audio cables.

But "loopback" is preferred, e.g. you can route the audio output of the SDR program
to WSJTX and at the same time route this to other output devices such as your head-phone
(if you want).

TU Dan!

[George Pap]

TU all gentlemen for the feedback!

George

I can vouch very strongly for SDR Console being perfectly matched for use with HL2. Has a very nice looking and polished GUI. It has CW sidetone, fully adjustable for tone and level, all built in. No latency issues unless you routinely work above 30 wpm then I don't know because I can't go any faster!

Also works very well with WSJT-X and therefore I imagine also all other data programs. I highly recommend it if you are a Windows person.

Also SparkSDR has a good built in low latency sidetone.

TU Max, yesterday i have received it and started setting the whole thing up. Managed to get great TX audio from SDR Console V3 and i managed to setup Thetis for FT8 with com0com for cat control and VAC for audio. Does the same setup apply for SDR Console too?

TU, Geo

[radi...@mail.com]

Yes George, exactly same setup applies and works very well. Also did not answer one of your earlier questions. Key/keyer straight in to HL2 front panel jack works very well with SDRC. Also a PTT footswitch to the ring of the Key/PTT jack works well apart from one minor bug which has now been corrected in the SDRC latest test version and will be rolled out into the main download very soon. Once that is done I don't think there is anything I can fault now on SDRC/HL2 combination with the exception that SDRC does not yet run multiple parallel receiver "slices" on HL2. It's not a feature I personally use but maybe some will want it, for FT8 skimming for example?

You may wish to join the SDR Console support forum(s) for further questions about SDRC or in fact many other questions you might have may already be searchable and answered on there. Somehow we've ended up with two official support forums but most of us with SDRC keep across both!

https://forum.sdr-radio.com:4499/

https://sdr-radio.groups.io/g/main/topics

The first one was supposed to replace the last one but the migration was not popular so they both exist in parallel!
