50 MHz - a Reminder

Post by G8GKQ » Wed Apr 06, 2022 2:01 pm

Don't forget that there will be a 50 MHz section in this year's IARU Contest in June.

The bandplan recommends 51.7 MHz. Probably best to start with 333 kHz DVB-T, QPSK, Guard 1/32, FEC 2/3.

For receive, you can tune there directly with a Knucker tuner and a Portsdown or Ryde. I would suggest an band-pass filter and a preamp (in that order).

For transmit, you can use a Portsdown 4 with LimeSDR, which will give you +1 dBm on 51.7 Mhz with a Lime Gain of 92. Or you can use a Portsdown 4 with a Pluto, which will give you -10 dBm at 0 Pluto Power (the maximum).
