Nice!

Here’s a video that describes programming the rt22:

I googled the manual. They’re called QT and DQT on page 05 of the manual. QT will be the tones. DQT will be the codes. I would provide more information if I had one in my hand to try the different buttons and see what does what, but I guess you will have to do that.

You most likely have a CTCSS tone or DTCSS code set on receive on the Midland that differs from the RT22 transmit.

Do a report to export them to CSV and then use Chirp to import them to your radio.

You’re wrong, Leo. Air, and what’s in it, is the conductor for lightning, not an insulator. There are better conductors and better insulators but ionized air is actually a pretty good conductor. But who’s arguing about a couple feet?

Yes, but you asked how to stop those notices that appear at the upper level and the only way to do that is to change your password at the MyGMRS level.

Yes, change your password.

The rule of thumb is that the distance between ground rods should be twice the length of the ground rod. Anything less results in minimal additional protection. The wire is used for bonding, equalizing the potentials of the different ground rods, not carrying the full current of a surge. The nearby ground system takes the brunt of the current surge. A water jet might be able to do it, but maybe cutting the asphalt is easiest.

Exactly. Best is to disconnect it before it enters the house.

If you use 8’ ground rods they should be driven every 16’. There’s no benefit from placing them every 8 feet. Code doesn’t require 4 gauge. It requires 8 awg. I wouldn’t cut the asphalt, but I would go under it. Burying the ground wire is fine, even preferable.

Less risk, but not no risk. The coax might still be at risk. What’s the breakdown voltage for the insulation of the coax? A long piece of coax exposed to a high voltage pulse at one end but disconnected at the other end can still be damaged. And what about the center conductor? It isn’t grounded unless you have done something to ground it. Depending on the design the antenna radiator elements are not usually connected to ground.

Welcome! Feel free to ask whatever questions you might have. That’s how everyone starts. We don’t do much one on one consulting because whatever questions you have, someone else is likely to have, or perhaps has been asked before and we can point you towards the answer.

That won’t protect the radio at all. Electrons don’t stop instantly and between the antenna connector and the power input there’s a lot of components that are at a different potential than the coax shield and center conductor. Yes, it’s not cheap. Tying all of the legs to a single ground rod requires changing the path of the discharge. Having a ground for each provides a straight path to ground, plus having more rods reduces the impedance going to the ground. In an engineered ground system such as a substation you might even see a ground mat, chemicals, and other things done to minimize the resistance and create a large bed of equal potential.

I’ve reported this to Rich.
