4m Brick PA

Post by radiogareth » Thu Jul 10, 2025 1:10 pm

This uses a genuine Mitsubishi RA30H6080M Module rated at 30W FM and suitable for linear operation too. Mounted on a large fan-cooled heatsink and built on a GM3SEK PCB with output filtering. Toggle switch for bias on/off, power LED and BIAS ON LED. SMA input and BNC output.
Enigma Components sell the module for over £80.
Delivers an easy 30W on FM and over 5W of DATV which with my beam was enough for the ERP limit.
SInce I bought a late-model MM up-converting transverter which does similar DATV power and RX too its surplus.
£80 collected at CAT25 or + postage by whatever means you wish.
