Reading comprehension must be on holiday here. In the original post, the licensing "thing" was brightly illuminated.
As to the mechanics of the situation: you probably don't need anyones' external controller to accomplish this task. As I posted, you simply mate the appropriate I/O's & program accordingly. What you do want is a service monitor to help in adjusting the final values of resistors & caps that you will need to match the audio paths. To control using dtmf will likely require a little head scratching on your part but I'm betting a latching relay tied to the signaling alert I/O pin will afford you the on-off you want. The hardest part to it all will probably be getting the audio levels set & the tonal quality right. I wouldn't be overly concerned about overdeviation unless someone has screwed with the factory alignment in any of the radios. Again, to make life much easier, you want a service monitor on hand while setting the I/O levels & tone quality. As to the duty cycle of the gear: You know this is not a very busy system & even a (2)mobile repeater will work, especially if it's got a fan. Those lil F221 mobiles are good units & failures are very few unless stressed from outside sources. An outside source would include lightning, power main surges/noise, building collapse, bad antenna/coax...etc. --- In Repeater-Builder@yahoogroups.com, "bkcarter33" <[EMAIL PROTECTED]> wrote: > > My local Community Emergency Response Team (CERT) has recently > obtained a UHF repeater (ICOM CY-F221S). > > It has two ICOM F221S radios linked together in a nice rack mount box. > > It has also been set up with a remote mic and speaker off of the > outputs on the chassis back panel. > The CERT group is licensed for the UHF repeater frequencies and they are in the public service band.
