Re: D4D receive light only activates during transmit

Steve,

A local ham also encountered a similar problem. It does light on when the radio is powered on, although the LED is reversed. The explanation could be something like RF signal coupling.

Thanks,
Adam

Well that doesn’t explain the green light coming on during transmit.

Steve,

Apparently your green LED is polarity reversed.

Steve,?

I saw your good soldering at a? glance.?
But usually this view deceived us. Check everything again.

>but once transmit is complete both lights go out.

Strange. I recommend check out voltages during this status. Then you will find out reason.
Relay or something around ?

Finding reason is part of hobby and fun !
Generally kit need effort to complete is worth more than soon completed.
You paid same price and you can play longer than the others.
Otherwise there are many completed product is the world.

Anyone have any ideas? Thinking I need to start by testing the transistors and work out from there.
