i was wondering if anyone would know the frequency offset on 440 ham radio the offset is 5000
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.
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.
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.
