WSAM454

Just a comment: The mag mount you mentioned comes with 13' of RG58 cable, which will have an approximate 1dB loss. That means that you will be loosing about 20% of your power from the radio, so if you are really putting out the full 5 watts, only 4 will reach the antenna. The antenna you mentioned does have more gain that the one mounted on the radio, so overall, it might bring the output up to about 6 Watts, which might be enough to make it into the repeater, but just be aware that if you were that noisy it may not be. Find the best place for the cookie sheet and antenna and keep it there. The base station radio (more power) you have planned will be most useful !

You may be able to "key up" the repeater, which means you will hear its squelch tail, but your signal may be too weak to actually "hold" the repeater and allow for meaningful communication. Are there any other repeaters you can try? If not, at least try using the radios on a simplex frequency and see if you can communicate with each other. That will at least confirm that the radios are working.

This site lists all the GMRS frequencies and their channel numbers. Don't worry about the other columns for now, just the channel and freq. Just look up the frequency and see which channel it is. If your radio does not use the "-R" naming, then just imagine that channel 15-Rpt is channel 23 and continue numbering from there. That is how you will dial it in on your radio. https://www.rightchannelradios.com/blogs/newsletters/gmrs-radio-frequencies-and-channels Most radios use CTCSS ("PL") tones. This site lists them: https://www.buytwowayradios.com/blog/2022/10/chart-of-standard-ctcss-tones.html Good luck!

If you cancel with them, then following the rules, you would be obligated to notify the FCC of a change of address, since the license is good and still in effect for the full 10 years. I do not think that there is a way to cancel you license . Another consideration: will HamRegistry be around for the next 10 years to protect you?
