In response to your Gm300s as repeaters, I have been using them for years without any problems, power up full(with fan coming on at transmit) and a 600 KHz spacing. I also have a pair of SM 50s working as a repeater with a much wider spacing. It has been operating for years now, without any problems. I will be happy to share more info.

It is down to the duplexer finding a unit suitable at the right price will be almost impossible, the 5Mhz split is ok as you can get cheap duplexers from Hong Kong 73 Steve ----- Original Message ----- From: "la88y" <llhorl...@gmail.com <mailto:llhorlick%40gmail.com> > To: <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> > Sent: Thursday, February 25, 2010 4:46 PM Subject: [Repeater-Builder] Pair of GM300 as a repeater > > > I'm wondering about the suitability of a pair of VHF GM300s as a repeater. > Is the shielding sufficient to allow 600 kHz between Rx and Tx?
