Re: [Repeater-Builder] Re: OT: Radios and Coms in TV and Movies

In the early 1990's I was at the Foothill College Swap meet in the San Jose area and there were several guys running around with the radio shack 49 MHz walkie-talkies that were modified to 52.525 Mhz. At that time, it was kinda cool, but my HT-200 was operating just fine on 52.525 Mhz (and still i

I would think it would be treated the same as the change to NBFM in the 70s (60s?) - the radios are lowered in deviation to meet the new specs and everyone is happy. (until you get a close adjacent neighbor) I think there are still TODAY radios in use that say "Adjusted to NBFM +/- 5 kHz deviat

As long as you turn the modulation down to 2.5kc dev max, that meets the "narrowband" requirements. The only reason for changing the I.F. filters is to re-gain the amount of "recovered" audio out the speaker that you had before. Or you can just turn up the volume on the receiver. If you cahnge t
