R.I.C.K. for GTX?
Moderator: Queue Moderator
Can the R.I.C.K. boxes for the Maxtrac, GM300, GM350, etc. be used for the GTX mobile? I wonder because of the RSS cable, mikes and other accessories being compatabile between the radios. If not, is there a way to switch around the pinouts on the cables or radios? If there is not a way to go that way... is there anyway to use 2 GTX mobiles to make a repeater?? Thanks!
Not without modifications, as the GTX mobile does not provide any type of carrier detect at the accessory connector. They also do not provide a squelched flat receive output, and do not provide switched B+ unless you relocate an inductor inside the radio. All in all, a real pain to work with! I've spoken with the product group in Plantation about it's shortcomings. They basically said it's designed to be a MOBILE ONLY. It's not meant to be interfaced with anything other than a speaker & microphone, thus the limited, non-programmable accessory pins.
All that being said, it's not THAT hard to make work, but it's sooo much easier with Maxtracs.

Then the question becomes: What is the easiest, cheapest way to get a 900 Mhz repeater online? I know the conversion of the 900 Mhz Maxtrac involves some retuning of the RF section of the radio. Seems to me there should be some solution to the project that doesn't involve sinking $3000 plus into a 100 pound rack mount repeater. Hmm, such a deal!
I build custom RICK repeater interfaces for most M100, Maxtrac, Radius, GM series radios.
No reason the GTX and Spectra could not be used for the transmitter as far as my RICK interface is concerened.
I would think that you would need a talk-arround capable radio for the transmitter, and that leaves the receiver that needs to have the RF retuned to the 896-907 range.
I know of a ham 900 repeater made from Spectra radios, so it may be possible to make one on the comercial freqs. I could have used one years ago for temporary intenerate use.
