Hi Jay,
Sorry you're having so much trouble with this...
-- Exception: -- Traceback (most recent call last): File "chirpui\clone.pyo", line 134, in run File "chirp\ic2820.pyo", line 110, in sync_out File "chirp\icf.pyo", line 303, in clone_to_radio RadioError: Did not get clone result from radio
Clone failed: Did not get clone result from radio Clone thread ended
This could just mean that it never hears from the radio at all. Have you tested your clone circuit with the ICOM software to be sure that it works? I assume you never see any progress bar movement prior to getting this message, right? Does the radio go into clone mode before this fails? If so, it could be that the TX side of the circuit is working, but not the RX side.
I have built the circuit you posted and had it work, but I usually use one of these:

$15 shipped is pretty decent, I think.
I have GPS TX MODE and GPS AUTO TX disabled. Is there some other setting in the 2820’s menu that might cause this?
Nope, cloning through the speaker jack should be pretty bulletproof (provided the clone cable hardware works). The GPS settings have no effect on speaker jack cloning, nor does anything else in the menu.
Also, can anyone suggest some troubleshooting commands I can send to the radio using Hyperterminal, etc. to verify that it is receiving commands? I have found lots of CI-V commands but nothing showing the IC-2820’s CI-V address; I suspect that radios with clone-only capabilities (no rig control) do not have an address, but there must be some command to trigger the clone-in sequence.
Nope. As you suspect, there's nothing easy you can do in a terminal to see if the radio is responding.
You said you can download your 2820, right? Can you send me your image file and let me try to push it into my radio? Maybe it's not the clone cable that is the problem, but rather something in the radio image. The radios will kick out of clone mode midway if they encounter something they don't like.
