Re: Using Line-1 out of SDR-Console to WSJTx Audio In

Tools->Options->Audio has some discussion of latency and how audio buffering can be tuned, in a limited manner, within SDRC.

So Bob. Two things:

(1) I think Simon is suggesting this sort of issue is best posted in the main SDRC Support forum, as this group is really intended for informal chat:

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

(2) Just one last question from me before you transfer this topic to the main Forum. Where is the RTL Dongle in the chain? Is it in "SDR" mode i.e with an antenna input, of is it in the path from the FT450 to use SDRC as a panadapter for the FT450? Sorry if I missed it but cannot see this specifically mentioned earlier?

Also apologies if this is a stupid question. I've only used pure SDRs with SDRC so I'm not very familiar with what is required to use as a panadapter. If it's the latter, could it possibly be a delay being introduced somewhere in the IF chain from the rig via the RTL dongle?

Hi Bob
Sorry, not a constructive comment
Max, ALL comments potentially can help me resolve this.


but just by way of comparison I
run WSTJ-X fed by VAC (this one https://vac.muzychenko.net/en/ )

Yes, I run the same paid version that you do.

So, check out the latest screenshot.
Side by side WSJTX
One, on the left, runs from SDRC
The one on the right runs from the Rig's USB-Audio-Codec.

Problem doesn't appear to be the WSJTx version as the Right-Side WSJTx is
near perfect dT.

I can't see how it is VAC unless there is some sort of timing setting I
overlooked.

I am not able to synchro tune the remote TS480 (freq remains fixed).

Smells like yet another firewall issue. You're on Win-10?


Diversity synchro remote setup

IK2CAW Rik
 
Edited

Hi all, I trying to setup this diversity synchro system but apparently I am missing something:

  • remote: SDRplay RSP2pro at IF of TS480 as external radio to V3. It works very fine locally. Server is correctly setup
  • local: IC7400 as external radio, synchronized with local V3 client. I have configured IC7400 as external radio with IF Out=IF out of TS480. It sort of woks as I see signal on the V3 client waterfall but I am not able to synchro tune the remote TS480 (freq remains fixed).
In other words I want to tune signals with local IC7400 and have the remote TS480 tuned to the same frequency so that I can listen to same signal both on the local IC7400 and on the remote RSP2pro via local V3 client.

Remote CAT port is managed with VSPE, local CAT by Microham Router.

If I connect to other ham's remote servers (SDRradio) everything works fine (in this case I deselect IFOut on V3 client). So the problem is clearly on my remote setup (maybe Omnirig ...).

Can you kindly provide me with instructions for this setup to work i.e. to have the remote TS480 following the local IC7400 VFO ?

Many thanks in advance for your help.

Hi Bob

Sorry, not a constructive comment but just by way of comparison I run WSTJ-X fed by VAC (this one https://vac.muzychenko.net/en/ ) and my PC is second gen i7 so nothing very impressive on the hardware but (just for info) I do run a dedicated GPU (GTX1650 Super).

My radio is HL2 (Hermes Lite). However, as a test I also ran it with my RTL-SDR.com V3 dongle. Note fed direct from antenna, not from another receiver IF output. 

With HL2 my DTs are mostly around +0.3 to max around +0.6. Yes, a few more than 1.0 sec and up to 2.0 secs, but individual stations so those will be their end.

With the RTL the DTs go out a little further to mostly 0.5 to 0.8, but nothing terrible.

Certainly not seeing what you describe (mostly +1 to +2 secs). I therefore don't think it is anything specific to SDRC. 

Which VAC are you running? Have you tried a different one to see if it makes any difference?

I also looked at the SDRC screenshot and I don't see anything much different in terms of CPU use or audio latency (mine is about 118ms) but your GPU use is 20% whereas mine about 4% but again, can't see this being a deal breaker. So again, it possibly comes back to the VAC as being a likely culprit?

Hope it helps.

Best

Max

Re: #rsp1a remotely on SDR Console and Raspberry #rsp1a

Kriss ,

 

That’s correct. There’s a new-ish Pi-based server for the RSP1A, maybe other SDRplays but I don’t support it yet. I don’t know how stable the whole concept is, also I don’t own a Pi!

OOPS!
Looking back on my post, I see you are using a Raspberry Pi. SDRC doesn't play with Rasbian as far as I know. So find an old W7 or higher laptop/netbook and use it for a remote server, such as mine are all older netbooks.
Doesn't require much computing power for server use, and a laptop has a battery that will let the server continue to operate during brief power outages.

Not sure what happened to my reply from last night, but will attempt to repeat it.
SDRC, when installed, also installs a server application. So no need of Teamviewer, Anydesk, etc!
One needs a fixed IP on the host computer (one attached to the SDR(s)) and if you plan on accessing it from outside your LAN, a free DNS service to resolve your IP if it changes like mine does once a month.
You can set it up for private use only, or have it available for anyone via the web.

Here's my thread on setting up SDRC to be a server:
https://sdr-radio.groups.io/g/main/message/51472


How to operate SDRC using remote servers:
https://sdr-radio.groups.io/g/main/message/51635

I operate five servers with 13 SDR's all open to the public. Servers on decent antennas in a QRM free environment are difficult to find, and I strive to keep them operational 24/7. Look for KA1GJU Super Stations on the remote server list.

There probably is nothing that can be done about it within SDRC if you already have it set to minimum latency. You also need to set your audio device to minimum latency if it allows this. If all this is already done, measure it and make it part of your time calculations.

Let's get really crazy here. Try LSB rather than USB? It probably won't help. But if it does that will be instructive and we'll have to sort this out.

Gentlemen,

I'm trying to run RSP1A as a remote receiver that I want to operate using SDR Console, I used this tutorial (https://www.youtube.com/watch?v=KDbOFftyEww&t=949s) but unfortunately my RSP1A is not detected by Virtual Here Client ... do you have any idea what the problem could be? I'm doing everything as described step by step but I don't want to work ... or maybe someone knows some other way how to connect RSP1A with SDR Console as a remote receiver ..... ??? thank you for all the suggestions ...
