From time to time I check out YouTube videos that cover the use of GMRS, and services licensed by rule (CB, MURS, FRS) and also ham radio which often comes up as a comparison. I notice that it is common to have errors in the presentation, sometimes fairly serious errors. And the comments by others, which may even be rude and arrogant, can actually have even more errors in what they present. So I will make comments, hopefully in a respectful manner and point out some of the pros and cons of Part 95 and Part 97 services.
Of course I want to be accurate and there are a few things that I would like to clarify:
1. Mobile, hand-held portable, repeater, base and fixed station can transmit on the main 462 MHz channels up to 50 watts output. And mobile, hand-held portable and base stations can transmit at a maximum of 5 watts ERP on the 462 interstitials.
But, if you have a station running 5 watts with a gain antenna, (mobile or base) and not enough loss in the coax, then do you avoid using the 462 interstitials?
2.Only mobile, hand-held portables, control, and fixed stations can transmit on the 467 main channels.
Does this really mean that I can not access a repeater from my home base station? There are times that we can access a repeater at some distance out and make it possible to communicate from mobile to base via the repeater.
3. When I contacted B-Tech prior to buying a couple of their GMRS-V1 HT's, I questioned why the power output levels were reduced to only 2 watts instead of an earlier version that I had read were 5 watts. They indicated that they had to drop the power to 2 watts to be legal. The only reason that I could think of was that they only had two power levels in these modified Baofeng radios, and one had to be 0.5 watts for the 467 MHz interstitials, so perhaps the earlier models had too high an output for those frequencies?
