Re: troubleshooting the bitx40 receiver - transmitter information

 

¿ªÔÆÌåÓý

Dear Ashhar:

Any idea when the troubleshooting the BITX40 transmitter video will be out? When I switch to transmit the transmitter stays in receive mode with a tiny shift in frequency. It was working but I suspect I may have left the transmitter switch on (just a guess) and now switching to transmit does not engage the transmit side. Not sure if I killed the IFR510, 2n2219a, switching relay or something else. I believe your step by step diagnosis, similar to your excellent receiver troubleshooting video, may help me isolate and fix the problem. Thanks an update on the transmitter video release update.

I second KF7RSF's comment. ? Can you please tell us what the red wire /speaker connection is you are using? It's not clear on the video.

Ashhar,


In the receive troubleshooting video, what is the unseen end of the red insulated wire connected to? Or nothing?
