Thanks for the response and forward thinking Marc. I have read your other post. Looking forward to additional replies in that thread.

Good Day Marc.
This weekend was a weekend of more tests. I even made my first 1/4 wave ground plane antenna. I mounted it on top an 11’ pole and walked around the neighbor hood. I looked like Moses, but I digress.
I took delivery of an entry level SWR/power meter (SureCom 102) and dummy load so I had at least something of my own to use. I have also started to make friends with a local ham who owns some additional test equipment. He was the one that inspired me to go for my tech license.
Using two different power meters (with dummy loads) I now know that my radios are outputting 4-5+ watts on all but the 7 mandatory low power FRS frequencies.
I confirmed the SWR of my Comet 712EFC and Midland MXTA26. Both antennas measure less than 1.10:1 across the whole GMRS spectrum. This was done with two different meters with consistent results.
My local ham friend also supplied a small digital antenna analyzer that scans the antenna system. Pretty cool! (Similar to an audio band impedance and acoustics analyzer I own). The output graph was nice and smooth and the resulting SWR measurements were substantially consistent with what was obtained with the SureCom. At least no gross anomalies observed.
I am starting to gain confidence that equipment is working.
I have also purchase some 1/2 wave Nagoya 771G and 1/4 wave 701G antennas for HT use as well as some Ed-Fong antennas to use. The arsenal is growing fast.

BTW, I have ordered a pair of the new Nagoya 771G 1/2 wave and 701G 1/4 wave antennas to try with my KG-805G radios.
I have also ordered the Ed-Fong GMRS roll up.
Going to be doing some more range testing around me when they arrive.
I am also look forward to winter around here, not because I like cold, but because the leaves will be off the trees and I am really curious to see how range improves in the absence of the leaves.

Here is another website I stumbled upon that allows you to enter two points on a map, graph the terrain between them and then add antenna elevation to both to see what amount of elevation is needed to eliminate terrain blockages.

Rodro123, I believe 95.51 was removed as part of the 2017 FCC update. My current understanding is that 95.1741 took its place.
