Does it do this when using headphones connected directly to the radio? You haven't described your audio chain, so that is where I would start. Ensure it is a problem inside the radio and not elsewhere.

Is your VOX turned off? VOX delay could be getting you if it's on.

Can you describe how your computer is wired to the radio?  Is it wired or wireless.  If wireless is it 2.4G or 5G?  

If wired, is there a switch you are wired through (normal operation) or do you have the computer directly LAN connected to the radio.

(But, it sounds like a VOX issue based on what you said--I'm just offering other ideas)

Hi Tony

Sorry, your sentence sounds confusing.  Is the computer directly connected to the radio or are you using 5G Wifi?  Or, is it that you are LAN connected to the radio and the 5G is for your internet connections.

If you are using the squelch feature found in FRStack, you could possibly experience this.

Check your Radio Setup TX menu.  Do you have any delays programed into the "ENABLED" RCA TX1/2/3 spots or the TX Delay spot.  On my 6500, these delays appear to be on both TX key and TX unkey states .  If you change the numbers you have to leave the page for them to take affect.

You need to determine the nature of your issue. 

Is the radio transitioning from TX to RX instantly when releasing PTT?  You can tell by the TX indicator in the bottom right-hand corner of the screen.

 If not, then you have a PTT issue to resolve.  If so, then you have an audio recovery issue to resolve.

Hi Tony

A quick question - if you key the transmitter but have set the TX output power down to nearly zero, do you get the same 2 second delay reverting to RX as you do in a QSO at full power?

Would be a useful way to eliminate RF-in-the-Shack from possible causes of your delay.

Please advise and 73

That is a different setting Tony (see now your are working with Tim in the same thread)  -  I was wondering if it was worth it to try setting the RF power out to zero.

You will not get any RF output when you key the radio with your microphone, but all the other transition between RX to TX and back to RX should take place.

My thought was to eliminate the RF signal getting into something like your router or computer from the equation, but still make the radio go through the paces.

Tony - An AGC-T of 0 is probably your problem.  You need to set the AGC-T so the gain is at at the "knee" of the AGC curve.  Zero is WAY too low for any band condition.  Review Section 11.1 in the SmartSDR Software User's Guide on how to set it.

You might consider rebooting the radio to be sure the radio is set to factory settings.

That really should be a last resort action.

Also check the Noise Blanker -- at high settings, it has a fairly long recovery time after TX. With slow AGC and high NB, I think this could act like your problem.

@ Tony - Isn't default NB off and the slider default Zero?  It has to have a wide range of settings to accommodate all users. 

If you don't hear things the way you expect your always doing good sleuthing to undo the recent settings changes.

https://k9zw.wordpress.com/2008/12/16/repost-snap-snap-photographing-your-shack-setup/ (which should be updated to include the use of cell phone cameras and screen snips) reflects the idea that when things work, mark-down/record/photograph ALL the settings that got you there. 

That becomes a sort of "home spot" you can then get back to.

Profiles help, but I still do screen shots myself.  YMMV, but it sure does save from the embarrassment of asking for help over a self-inflicted settings change.

Glad you are back in a good place,
