I think I need to re do the station control. I built that 35 years ago, it has a big open ceramic base relay for T/R switching, a bunch of small relays for muting, switches for antenna selection, transmitter selection, receiver selection, what AC from which transmitter keys things. While the switches are good for the power, some have poor isolation and RF is floating around in all the AC and muting stuff. Its also designed wrong as the PTT is by each transmitter, not one switch on the microphone. I want one 12 vdc PTT and relay that will key all the transmitters (not at once) separate from the RF, LOTS of keying and muting outputs in a labeled rational way . T?R relay in a seperate box, with another relay that shorts the RX output to ground, and all switches with better isolation and less SWR impact at higher frequencies. The current setup is very handy to pick one of 4 antenna's, one of 4 high power transmitters, one of 7 receivers, and the ability to have a tuna in only the TX side if I want, along with a watt meter/mod monitor output, all in one handy box at the operating position. The new setup will not be as slick I think, but might work better. It means tearing everything apart and re doing it.... I have 3 big transmitters, a 32V3, a flex 5000, an Icom 756 pro2 that will be the exciter for two big transmitters and the K7dyy rig coming, along with various small sdr rigs, the Heathkit MT-1, the Neuvo 75 and other stuff.... I bought a couple of Alpha Delta 4 position coax switches and an old B+W 6 position switch which is just a regular switch in a box with coax connections on it, not good for a lot of power and no isolation.
