Re: QCX20M #585 Transmitter Inoperative
It might be interesting if someone would write a set of test programs that supported individual function testing. In this case the code would activate only CLK-2 on the Si5351a and thus allow signal

Re: QCX 80 Transceiver - Connection for a Straight Key
Hi Robin. I have experienced this with other setups as well. A mono plug in a stereo socket will cause the ring and ground of the socket to short, thus keying a "dah". Its simple to a stereo

Re: U3S drift/chirp - again!
Ian, I did some measurements on my U3S with OCXO tonight. Calibrated a warm TS590S (TCXO) on air 5MHz and to my rubidium 10MHz to within 1Hz in WSJT-X. Condx bad for 30/20m beacons tonight. Listened

Re: FT8 for U3?
Come to think of it...this is QRP Labs and about the U3S kit.Lets remember what QRP is ... QRP operation is not 20,30.40.50+ watts like QSO modes are usually abused.When I say abused I mean 30+ watts

Re: QCX 20m - Almost done... can't wait
Hi Keith, There are about 30 SMD devices including two 8-lead ICs (not as close a lead pitch as the FST3253 as used in QRP Rx ).? R's and C's are 0805 , with four SMD can-type electrolytics.? The

Re: QCX Manual
Most of the toroids are easy. The only challenging one is T1; it takes a bit of work to get all the wires in the right holes.

Re: Winding Tip for 80 Mtr QCX transformer (T1)
Good idea John, I have a few trimmers in the junk box that will do the job and it might give an idea how much extra inductance is required so I can calculate the number of turns required Thanks Robin
