Bill, we're using 927mhz to link our 2 440 machines together.. The one site is very populated and did suffer from some intermod from 900mhz paging on the hill.. A pass cavity fixed that.. The other site is close to a city, actually looks down on it, and does get brought if not in tone squelch mode. Although the one repeater does come up, I've never heard any actual cordless phone coversations so that could be paging also.. This site also has an omni ant. for future plans in linking in a 3rd site..
The radio's are 30w Johnson 8655's turned down to about 10-15w and are running simplex.. With that in mind, we can usually hold our freq. with any of the cordless folks.. There are a few Kenwood radios I would consider using for linking as well, but got a bunch of EFJ's in Dayton a few years ago.. I'm sure there are some Motorola radios as well, it just that I'm not familar with there line.. -73, Pete N2MCI --- In [email protected], "Bill Powell" <[EMAIL PROTECTED]> wrote: > > > Looking to replace a short (~1600') wire link between control site and > transmitter with an RF link.
