Guten Tag Stefan

Main amp is a single Decca 5501 module and has a smit trigeer so can take sine or square wave. I use square wave input for Opera and QRSS because of the divide down from 5 Mhz main VFO. The input to main amp needs around 7 – 10 volts. At present I use VFO 472 – 479 Khz /4001(SQUARER)/4017 DIVIDE BY 10/tc4426 driver to main 5501 amp input

When I get time I will QRO but need to build an intermediate RF amp between TCVR and main MF amp

Which input signal does your main MF amp need? Rectangular? Sine? Which input-Z? Which amplitude?
