Hi Paul I have a 7000 with no audio on rx and will not tx. I think its the logic board are these boards available? james

IC551

James, Keep up the good work. Keep us posted. We all appreciate your information. Bob W4JFA [email protected]> wrote:

Checked? CW tx using keyer input and radio not going into TX mode .more work to do ....

Hi Geoff looks like dds 2nd osc is ok at 124.032 and 1st local osc varies with tuning knob so looks like front end might be ok and the dsp board may be the culprit. i need to confirm signal present at

Hi James, If you confirm the audio amp is ok then you need to look further back. At least now you know that if you fix an upstream fault you should hear something. The fact that you acquired this

tried with an earphone in the headset socket top rhs next to band switch ??

Hi Tommy i have been checking the TRX videos -they are good thanks james

Hi J.D yes will try TX tonight james

Thanks Bob good point - will try tonight james

Late to reading this thread, but have you tried a full reset to see if that makes a difference? Other than that it may be time to troubleshoot the radio. Does it transmit on any mode into a dummy

James Checkout this troubleshooting for “no audio” from TRX LABS https://m.youtube.com/watch?v=a3OTomZtnvs Tommy KF4RWG [email protected]> wrote:

You need to check transmit. You said you had no mic so put the radio on CW, turn on break in, insert a plug into the key jack. With dummy load, do u get a carrier? This will narrow it down to TX

Hi Joe Yes checked squelch and rf gain and associated menu settings No joy so currently probing around the circuitry to see if any clues

I got into this thread midstream.? Did you check the setting of the SQ/RF control and the setting of Set Mode 7?? Maybe someone else covered this but it may be something simple. 73, Joe, K1ike

Hi Geoff Yes I will take your approach. I think the audio output is accessable and a good place to start to check for supply voltage. James Vk2vjz

James, I'm not a fan of the shot gun approach to fault finding. Start from a known point of trouble, in this case it's the audio output. Using the circuit schematic it would be my suggestion to start

Hi Rick Yes that's pretty much what I did . It reset everything back to defaults but still no Rx or audio Just dead Looks like I need to open it up and check all the regulators Thanks for your

Hi Neil Tried just about everything as you mentioned. Looks like a hardware issue . The only thing I haven't tried is a full reset
