And, of course, depending on the license(s) that you hold.

I have SureCom SW-33 and I have Diamond SX600. While they mostly in agreement when measuring power and SWR on 2m, they wildly disagree on 70cm and GMRS. I decided to trust Diamond. Surecom measurements are inconsistent even with dummy load. Another thing to consider is that measuring SWR with HT and HT antenna is a tough proposition. HT antennas are designed to work when you hold HT in hand and your body is capacitively coupled with it. Surecom "stick" is comparable to 1/8 wavelength on GMRS and it will change antenna characteristics when inserted between HT and antenna. Same with using pigtails. I do not bother measuring SWR on HT antennas because of that. Measurement equipment introduces a systematic error that is big enough that you can't trust the measurement, Surecom or not. Measuring SWR of Fong antenna or mag mount antenna is a different exercise. In case you're measuring at antenna base, you will get correct SWR of the antenna. In case you're measuring at transmitter, the loss in the cable will lower SWR, the bigger the loss the closer your SWR to 1:1. Do not obsess with SWR, better measure the power at antenna base. SWR does not directly affect efficiency of the antenna, it is indirect metric of the loss in your transmission line and (very) indirect hint at if transmitter will reduce power or burn out.

Good Morning Ken, The following is a listing on very good qualty equipment listed on ebay new and great price and he or she is still selling them. I listed this some time ago. This is the link to the post I made. https://forums.mygmrs.com/topic/1685-this-is-a-deal-on-vx-2200-uhf-45-watt-89-ea/

Agree fully... but I grew up in a time when it was common sense not to video record yourself doing something stupid or illegal. LoL It seems as though people today have lost sight of that. Instead, people seem to think it's a good idea to record it and post it online for the world to see.

Answers... 1) No. Your guess is right. A repeater repeats only one frequency at a time. (Well, there are exceptions, but not that would apply to GMRS.) Ham and GMRS are different radio services and cannot interoperate. However, it is quite possible any given piece of equipment could operate on either the ham 440 band or GMRS, but never simultaneously. 2) It all depends. Fixed location, mobile, (car/truck, etc.), handheld? Terrain: line-of-sight, obstructed, vegetation, etc. Post back with more details. 3) You can listen to whatever you can receive. It is only transmissions that the FCC regulates. Well, ok, there are exceptions like for mobile phones etc. and I believe there are, in some cases, rules about repeating what you hear to others. Welcome to GMRS.

#1. Congratulations on getting your ham license! #2. I am not specifically familiar with the GMRS-50X1. But, knowing the GMRS-V1, and the FCC regulations, I would be quite certain that you will not be able to get that radio to transmit on anything except the GMRS frequencies. You could probably program in other frequencies to receive, but not transmit. #3. There is absolutely no way to determine over-the-air if a radio is GMRS certified. I cannot tell you to use a non-GMRS certified radio on the GMRS channels. However, I can tell you that I would not personally be the least bit concerned. I can also tell you that any Part90 radio you find is (very) likely to be a much better radio than most of the currently marketed GMRS certified radios.
