Recording myself on CW not working

[JJ4SDR]

Hi,

I tried recording myself on CW just now using WAVE. Done that many times when I am on SSB. Did not work.

On SSB, I use VAC and to hear the side-tone on CW I need to plug headphones into the from port on my 7000 DLE MKII which is an "extra" step.

Is there a work-around for this? I am a little disappointed at learning that many of the things I like doing like CW isn't as straightforward on this radio as it is on traditional rigs. That doesn't mean that I am not glad I got this ANAN as it really shines on SSB and packs many features that I didn't have before .

Working fine here with or without VAC enabled. I did nothing except press the record button, then played it back with Thetis' WAVE utility. However, unless you're using the experimental ChannelMaster.dll file, then you'll likely need to ensure that VAC is engaged to record the CW sidetone.

Sample .WAV file attached.

Like what?

Paul,

I have no idea what that "Master....." dll file is all about. Never heard of it.

On which form do you enable the CW side-tone to be recorded?

I am all VAC here and it bugs me to have to don another pair of "cans" just to hear the side-tone (that pair is plugged into the front "Headphones" port on my ANAN 7000 DLE MKII.

First, ignore my reference to the experimental ChannelMaster.dll file. It's not required to record a QSO with your CW sidetone.

Are you attempting to record your QSO with CW sidetone in QSK or Semi-Break-In mode?

To test with a clean slate, I just re-installed Thetis 2.9.0.6. While in CW QSK mode, I pressed the REC button, sent out a test message over the air and stopped REC. I then pressed PLAY and the receiver together with the CW sidetone played back fine.

Semi-Break-In CW was tried next. After setting a reasonable CW delay time, I tried recording the receiver and the CW sidetone. No go. The receiver records fine but not the CW sidetone.

So, try it in full QSK mode. If you don't like to hear the receiver between each keyed element, then delay the receiver recovery time in <Setup><DSP><CW>. Ensure that the QSK box is selected, then increase the Delay setting to a value that works for you.

Hi Paul,

When I am on CW I use semi-break most of the time and from what you are writing recording won't work. I wanted to record myself in a QSO some time ago hoping to be able to email the audio file, but it didn't pan out.

Curious about QSK: why would would the record feature work but not when I am in semi-break mode? Will give QSK a whirl and report back a bit later in the week!

Thanks Paul!

It's a function of how sidetone audio is digitally routed in Thetis. In QSK mode, the sidetone comes from the receiver, not the internally-generated sidetone oscillator.

So, when using QSK mode, you'll be able to record both the other station, and your own CW on the air. The effect will be the same is if someone else is recording your CW transmission and that of the other station. Of course, if you dial in recovery delay to make QSK more like semi-break-in, the receiver recovery delay will also occur in the recording.

Anyway, try experimenting with recordings in the QSK mode, then dial in the amount of receiver delay you like to replicate semi-break-in.

Because the audio stream that goes to the recording function only contains the output of the receivers, not the sidetone.

Paul beat me to the post but here's some additional information:

The sidetone is generated in the FPGA and is not sent back to the PC over Ethernet to Thetis, and Thetis is where the audio recording is done. Thus only RX audio is recorded.

IMHO this is something that needs to be fixed. It is as simple as encoding a single bit into the UDP data stream that brings the IF data from the FPGA to the PC. Or even just stand up a separate UDP data stream for sidetone.

Or, better yet, do away with the key input on the ANAN hardware and make the key/paddle/keyer plug into the PC and generate the sidetone in Thetis.

The reason this all works for full-break-in QSK is because you are not actually hearing sidetone, you are hearing your own actual transmissions with RX1 remaining activated 100% of the time, i.e. not turned off during TX periods.

Thanks very much for the responses!

Best!

Recording works swell in QSK mode

Thanks all !
