Hi Mal, I moved because I was on top of a Loran line at 137.696 and because I was using a pre-programmed keyer chip that wasn't set up properly for QRSS3. I should have the new keyer done soon and th
Hello Gary & the list, I changed some settings on the keyer and also moved frequency at that time. I need to be careful since even small changes made while on the air will be recorded and reported on
Hi Mal, Late today with the post. I have been shopping in YORK (not NEW YORK) Hope you stopped at the railway museum, it's my favorite thing in York. Only visible signal was WD2XKO on 137.7 khz WD2XG

Hartmut, Thanks for the capture. There is a cw i.d. before the QRSS G and also before the J, which makes the QRSS elements elongated. The new keyer should fix this problem. -- 73 Warren K2ORS/WD2XGJ
WD2XGJ is making an attempt at QRSS30 on 137.7798 kHz. Warren (fingers crossed!) -- 73 Warren K2ORS/WD2XGJ FN42hi http://www.w4dex.com/wd2xgj.htm Off until either: 1) I fix the keyer 2) I finish buil

Alberto, Thanks for the reply. Do you think that having I/Q channels available would have any advantage for QRSS or other LF modes? -- 73 Warren K2ORS/WD2XGJ FN42hi http://www.w4dex.com/wd2xgj.htm th

Hi Alan, The Decca Litz I used was from the transmitter tank coils, not the external antenna loading coils. The Decca TX I got from Andre N4ICK (Andre got it from David G0MRF) was originally on 70.23
