Much cheaper JUMA 136kc TX as Tx-2200A http://www.nikkemedia.fi/juma/ I built this tx already - it works fine, but dont have antenna so far ... 73 Uwe, dk1kq
Uwe, Yes the Juma TX136 and TX500 are very FB transmitters, and they have a receive bandpass filter, rx converter and keyer built in ! I have both - I've only tested them on a dummy load so far. -- 7
