What group? I only see you.

Welcome to our wacky world!

You can't boost the output of the radio to overcome losses downstream from the radio. The FCC limited the radio's output to 50 watts so you have to eat the losses.

Check Amazon for a Mean Well Supply. These are as good as you can get without the high prices charged for ham radio supplies. Many public safety agencies use Mean Well supplies in their repeater locations - and solid, clean power is often a critical life safety issue.

Go to the FCC site and enter your FRN into ULS (Universal Licensing System) to see and print your license. The FCC doesn't notify you of grants,

A lower-gain antenna works better in areas where the signals can reflect from many surfaces (multipath). Gain works two ways, not only by increasing the radiated output but also by increasing the received signal. In an urban environment lower gain helps reject multipath signals, while in a mountainous area, it reduces the multipath reflected from hard walls. YMMV

While the regulations agree with you, human nature would give more weight to the person being directly targeted. Showing the interference happened every time or most of the time they keyed up would show the interference being targeted rather than generally being the south end of a north bound donkey which carries more impact.

It can be reported to the FCC as an intentional interference but the person being targeted would have a better chance of getting action than another user being blocked from the channel.

What mode did you select for the squelch tone? To set the radio so it transmits tone only you need the mode as TONE with no receive tone. If you set the mode to TSQL the radio automagically assigns the transmit tone to the receive.

The Cotres are not approved for service in any band.

Several in the ham clubs I belong to have the Cotre 001D and the 004D we use on our local DMR net. They aren't the best on the market with a very low power output (around 2W) but they can access the local repeaters most of the time. They don't replace a good DMR radio, but they are fun to play with.

The accepted usage ratio is 80/20 with the radio transmitting only 20% of the time. So for 48 hours of backup, you would expect to draw 15 amps for around 9 1/2 hours, which I feel is high for a GMRS station. I would set the transmit figure to around 8 hours or 4 hours per day for a total of 120 A with 80 A on receive.

Are you trying to use a repeater or contact someone directly? Repeaters must be programmed in designated repeater locations on most GMRS radios. These are usually locations with an R designation on the channel number.

You are correct in that this repeater owner has no right to tell someone they can't access those frequencies. If the users are using the repeater for more than an incidental contact, then the owner does have the right to request they stop, or he can turn the repeater off for a period. The rules are a little murky regarding private repeaters, but the uncommon solution would be for the repeater owner to use some common sense regarding the fact the repeater is on-the-air to begin with.

I sincerely hope you are just spouting off and not serious. Deliberate interference is against the rules.

What radio? It would help everyone if you told us the radio, model, and if you have the programming cable needed.

Your data is recovered from your FRN number. To use a different address, you need to file a change to the FRN database.

Back in the 70's I tackled my power noise on my CB using a pi filter. It's an axial feed capacitor with bleed resistors on the input and output leads of the capacitor. Fixed all the power issues,

And LMR400 has 1dB of loss for the same length.

This method of testing coverage is only as accurate as the receiver used, along with the height of the receiving unit's antenna. Drive tests are often used to test cellular coverage, as their ability to get into the "nooks and crannies" directly translates into revenue for the site. They are also used by public safety agencies to test their coverage areas for the same reasons, using the same equipment from the repeater supplier.

Well, a 6dBm gain antenna won't affect the area you could cover as the radiation pattern wouldn't be that much different from a unity gain omnidirectional. It would flood the area with 4 times the power fed into the antenna, though. You may want to consider the MFJ-1917 Telescopic pole for your antenna mast, it reaches a tad over 40 feet high but collapses down to less than 5 feet.

The coax used for mag mounts is very lossy in lengths over 25 feet. You are better off using a half-wave antenna with LMR 400 or equivalent cable.

A VNA is a better choice as it not only measures SWR, it can also measure cable losses, tell you if the antenna needs lengthening or shortening to tune it to a frequency and display the SWR across the entire band.
