John Coleman/WA5BXO had this idea a while back... How about a single 4CX250B modulated by a pair? The tubes are small and plentiful. An RF choke to the plate, a coil tapped for 40/75 (wherever else) switched from the front panel, final sub-assembly on top of, or in front of the modulator sub-assembly seperated by aluminum plate, or put the final in the right-rear corner of the chassis, the modulator in the right-front corner of the chassis, aluminum "T" near the center of the chassis, to seperate the rx/exciter, and seperate the final from the modulator, build some small VFO that controls both tx/rx, a varactor diode for RIT control, a single IC w/PLL for the VFO... lots of neat things can be done. 73 = Best Regards, -Geoff/W5OMR
