The transmitter requires 24 volts for the varicap tuning and 12 volts for the rest of the circuit, the PA requires 36 or 45 volts (some explanations come in part 2 February Rad Com, Hugh M0WYE has given you some details in his reply), I have provided a 24 volt stabilised supply and from this a second regulator for the 12 volts, the 36 volts supply is unregulated, there are no specific details regarding power supplies in the articles, power supply options are left to the constructor. Let me know if you require any other info, if I can help I will. Regards es 73 Gary G4WGT. -----Original Message----- From: owner-rsgb_lf_group@blacksheep.org [mailto:owner-rsgb_lf_group@blacksheep.org]On Behalf Of jan-martin.noding@telenor.com Sent: 07 February 2003 11:34 To: rsgb_lf_group@blacksheep.org Subject: LF: G0MRF's class D transmitter for 136kHz (Radcom January) Supply voltage seems to be a somewhat obscure.
