You just said what the offset was, only you're missing a decimal point...i was wondering if anyone would know the frequency offset on 440 ham radio the offset is 5000
Or .005 GHz.I am not quite sure I understand the question you are asking...
On 440 (or 70cm), the offset is + or - 5 MHz... which would be 5,000 KHz or 5,000,000 Hz.
Running duplex, as in a repeater is a tradeoff. It's a tradeoff between transmitter power output, receive sensitivity, receiver bandwidth, available spectrum for separation, and cost.I took the question to mean why is it a 5 MHz offset when VHF is only 0.6 MHz offset. I was thinking the same thing last night while programming 65 repeaters into my new HT.
In terms of amateur radio I'm not sure what you mean by "VHF high" but if you're referring to 2 Meters, how would you do a 3 MHz offset? There's not enough bandwidth to do so.I'm surprised there isn't an official allocation in the band plan for field expedient VHF high band repeaters with a 3 MHz offset.
Reminds me of Texas 6m repeaters. Band plan calls for 500 kHz offset but nearly all of Texas' are at a 1 MHz offset.
