Re: No TX #ubitx

​no, he means the 2nd  connection for power to the power amplifier.

On the bitx40 it is a separate 2-conductor plug/pins

on the ubitx it is an additional wire on the 3-wire power connector....

if you don't have power going to the pwer amplifier....won't have any output

IN TX, the heatsink should go to +12 V DC.  you can check the tab of the irf510 with  voltmeter

By PA supply wire, do you mean the wire to the speaker/headphone jack? If so, yes that's hooked up. It's working as a receiver (i.e. I'm copying activity on the bands) playing through a pair of headphones.
