Re: How do I power the 49er ?

Hi Dave. Just disconnected the antenna and there's a lot of hiss on the output. Of course, the band is flooded with signals tonight due to the SKCC Weekend Sprint going on so it's much busier than it was last night. But regardless, with just a pair of earbuds on, it's very hissy. On very weak signals, the hiss makes it very hard to copy any weak signals.

Aaron,
What does the audio sound like with the antenna disconnected?? Are you hearing 40 meter band noise, or are you hearing audio hiss from within the 49er circuitry. I have one working and it does not have hiss when the antenna is disconnected.? Also, what are using for the 12 volt power supply?

Hello Norbert. I'm glad you found the solution. Was just about to respond when I read your latest post. Glad you got it resolved.?
I was wondering if you could do me a small favor. Once you power up the 49-er and get a chance to test it out, would you please report your findings on the quality of the signals coming from the audio output of the 49-er? I'm chasing down an issue with what seems to be excessive hiss - not band noise - coming from mine and since I've never assembled a 49-er before, I'm not sure how it's supposed to sound. Having another example to compare mine to would be a great help in determining if anything isn't right here.
Many thanks... and best 73s.

Got it, in finding some minor differences between the instructions in the QST and Farruk's link. I re-read the whole thing and page 22 on the QST instructions clearly states;
"12V power for the Forty-9er is taken from pins 1 and 3 of the J1 header on the Nano/VFO board."
