As advertised by Amazon 1.6 Watts @ 12VDC good to 512MHz. Believe what you read from purchaser comments! Too bad I read the comment from WA5BDU after it was in my hands! (With a name like Nick Kennedy (WA5BDU) he might be Irish and a well-known ham homebrewer. He has published a very understandable piece on homebrewing Crystal Filters.) I will not denigrate the above amp by calling it a piece of Crap, but I had terrible experience with trying to make it work. More than 6VDC and it oscillates and the most I got out of it was about 500milliwatts on 20M. The $18 price was like a siren's song that resulted in a shipwreck! With no time to scratch build things I have been making small purchases from Amazon of built boards in hopes of fabricating rigs using purchased modules. So, learn from my sad experience -- avoid purchasing this unit. If it seems almost too good to be true, 100% of the time it isn't true. 73's Pete N6QW
St. Patrick, the Patron Saint of Engineers, I was told invented Green Beer. It seems this was his secret weapon to convert the then pagan Irish to Catholicism by getting them drunk on beer. But that may just be Blarney! Were St, Patrick alive today would he be a ham? We do know of one Irish Jesuit Priest who was a well-known ham, 9N1MM , Father Marshall Moran in Nepal, the Voice of the Himalaya's. More tests with the RF Board and indeed the addition of the Band Pass Filter cleaned up the traces. I now get close to 2 VPTP on 40M and less on 20M. I used a BPF (dual 20/40M) built for another rig and noted before that 20M seemed a bit "hinky", so I need to revisit the 20M BPF. 20/40M BPF and SSB Transceiver Board RF Amp Board (Green ~ In Honor of St. Patrick) There are many stories about St. Patrick, and it is interesting to note that four US Presidents have Irish Roots: Biden, Obama, Reagan and Kennedy.
