You should look closer at my previous posts.??I have used a 12v battery pack, and 12v 1.2A converter. Then I connected a 12.6V 4A converter for radio, and PA. Finally powering the PA with a 20v 4A separately. There was no difference is noise from the battery on up to the 20v 4A supply. But there was a difference when I tuned the bitx from 7.8500 to 7.8350?while receiving on 7.850 on a SSB SW receiver with all settings set to normal, not DX and the antenna retracted. And SSB tuned for most natural tone, and the received audio was weaker than expected. Now it's all over, it was obvious I was transmitting on a different frequency than I was monitoring. Like when I tuned up and down for my friends transmission.?I was only able to hear mine because of the close proximity. Now, how do I get a replacement?
