Jim, The SMD parts are assembled on a Panasonic pick and place. No chance of a reversed diode. What is, however, possible is that the DC connector, which is hand soldered, hasnt been soldered

From my post 71040: There's an updated schematic in this July 26 2019 post from Farhan along with a list of changes: /g/BITX20/message/70551 As he states in that post, it all got

That would be nice. Mine works fine on the external power input but 6 brand new AA cells in the battery box (9.56V) wont even light it up. I did check and have the 9+ volts on the PCB terminals but

Check hfsignals website, and the files section of this group.

This may not be going to the right group. Is there a manual available for the Antuino? My unit arrived today. I thought I joined the Antuino group but I see the last posting I received was on 8/17.

Thank you so much for your help Woody! I'll try to get my hand on a small ceramic cap and let you know if this resolved the problem. I'll also try to salvage the ferrite sleeve from an old cable. I'll

Used sticky back copper foil to line the plastic case on my SDRPlay. Worked well. Cleaned up some noise issues. Jim WA3APC

I bought a roll on Amazon some time back. The copper tape is handy. One thing to note is: The tape claimed to have conductive adhesive. There was absolutely nothing conductive at all about the

So textbooks cost $1K/year, tuition is $20K, and it's the TEXTBOOKS that are the problem? Bullshit. If textbooks were free, a year at university would decrease by 5%, or about the amount the average

No, the vast majority (aka a "great part") of student debt is not due to the high cost of student textbooks.. A $20-40,000/year university is not suddenly rendered 'unaffordable' by $500-800 in text
