We have a problematic Astro Spectra Consolette with tone remotes on a trunked system. Is is possible to replace the ASC with a Quantar station (running it as a subscriber unit, not a repeater)

Slight Hijack: Anyone know what Burndy or T&B die you would use to crimp the 350 Amp SB Series Anderson Powerpole Set? (or if it's even possible)

I don't want to try to interpret it but you might look at NEC 2008 392.7 "Grounding - Metalic Cable Trays" and Article 250 Part IV (250.80-250.86) and 250.96. Key question seems to be is this rack "supporting electrical conductors" per 392.7 and does the NEC apply. Article 250 s...

I'd like to know what is the best way to connect a mike phone to a two-way radio repeater. In between the mike and the repeater will be a controller that will only allow audio to pass when it receives the proper DTMF "link On" code. The controller will be responsible to key up the repeate...

Bump! I just picked up a pretty clean MW520 / F5201C. Any takers on the fuse value?

It also uses a unique version of the programming software. The normal GP300 package will not work.

BNC adaptor HLN9756 is what you want to connect it to the service monitor. Henery Radio also sells a non-oem verison.
