Ok, the power supply and controller is probably doable, but no exciter currently. Oh well, I was hoping there was SOMETHING that could be done to repair this obviously poor excuse for a repeater.

Thats great. Also, does anyone know what mods are >needed to run this unit with an outboard controller, as the Spectrum >one sucks. Any and all help is GREATLY appreciated! > >Kevin >K2KMB > Here is what I'd do: (in the short term) 1.) Take the Spectrum exciter out and throw it away. 2.) This next step is optional: Smash it with a hammer so you never have any thoughts of reinstalling it. 3.) Install a used Hamtronics exciter in its place. 4.) Gut out the old control and power supply circuitry from the Spectrum. 5.) Install a NHRC-4 controller. 6.) Hook it to a Astron RS-35A/M power supply. (in the long term) 1.) Save some money. 2.) Throw everything except #5 and 6 away above. 3.) Build or buy a real repeater. No I'm not joking. Kevin Custer Yahoo!
