Which InReach device do you have. I've been meaning to get a handheld GPS for various trips, and was looking GPSMAP 67 with the InReach included.

Yea, plenty of traffic today on a set of ham repeaters that are not normally linked.

Look at hamfests or ebay. I paid $400 for my TKR-850, and I've seen a pile of them at the past 2 hamfests for only $600 (I bet they would haggle). https://www.ebay.com/itm/226048057405?itmmeta=01HSHB2F643BSH9B3Y7YX7EVA1&hash=item34a183a03d:g:UtcAAOSwJCVl9OK5&itmprp=enc%3AAQAJAAAAwEF%2FByVwUUmCl%2FrSSYnqjIKsJDuuv%2BUF61HYqlhp%2Bl0UQInVAy1%2FCs0ZUmjcqVxV85Jr0xLhK%2FY92GLCMomKzm1FEXDp%2BQpqtdPw3xYprvgtU9643vKqX3HjuqAuWVvSSuFzMnpJNrHZGdVJCrBL1QPYPi%2FqiSuokF66kwG%2F2wwBC9bPWlHY9j6quv8J5soB1N1VzJJC40eIFSrhbzIyDisTk3RfFrG8UaHKSOGsoMrGjCDhJxRaGm8ph0GHewvT9A%3D%3D|tkp%3ABk9SR6zziavMYw https://www.ebay.com/itm/386631482370?itmmeta=01HSHB3RKHS3ZKZJ4SYYPMY15T&hash=item5a05083c02:g:mi4AAOSwOg5lozE6&itmprp=enc%3AAQAJAAAAwD6YdARKhicet%2FJCqsdaQ%2FNO1DooBikEygrcPjnosm5ovx92qKiNDmmQJ6dQVo23GdFlYV7tlSLK6%2B2L0grP84qtgJ3tIDWYGFPEiG2KT6%2F6l3EJNOVdf%2FuRC6v9VeQD808EGQnNlwmzv8eRP8RSKUeqxoxrykFr4Y63N%2BYt0ABrk%2B04%2BbKU0VFkhN3rGpmHs17xTQC0z96ui0QIF3r%2Bb7Zo98aglrB3A8HiF0kvYnuqaNavZeOZKCsOiXZHWBZ8mQ%3D%3D|tkp%3ABk9SR_6Jj6vMYw https://www.ebay.com/itm/186330130294?itmmeta=01HSHB5FGYB0DNN6TCJPT9G53M&hash=item2b62242776:g:lkcAAOSwmjFl55rG&itmprp=enc%3AAQAJAAAA0GhDq3Q60ViK0xGgPO0ErM%2B5CQjGV2gizzQB%2BTDIOQIOrHPspeu9XSyISNUpb%2FJV9FAQZfX27azoe1KS2YxF8l8M7vFjBQl3oIx%2FANIs9oHlN8tDtucAgFnXy5wwfWYRNrYIb%2BTQpAFAi846ftGP72nDAV491up63tmCBwGDxRENOLY15J7tCoCnHH53Atz5zfAKwfZDD3JImmOS3r6mtVsFlcj70oIGyBBYNBoKZlc9OA9nUkZbYAU6uKH31zWTjc1rjrH1y4soVKvw93H2elM%3D|tkp%3ABk9SR8j4lavMYw Three examples................

I would consider his comments constructive. Iirc, he himself tried at one point, and there are about a dozen other people here that tried. It's not worth the effort as it never works out. Besides, as he pointed out, you could have just bought an actual repeater for the costs of the 2 radios you just bought.

Could be input tone changed, could be leaves are growing and your line of site is gone now. You could be hearing simplex users on the same frequency as the output.

If everyone gets their tech license, you can use it anywhere, and may be able to use nearby equipment (repeaters). There are tons of BSA troops that have commercial licenses on business itinerant frequencies. Troop owns a fleet of 20 radios, and they go to any group stepping away from the camp. That is also an option. No matter what, it boils do to your troop needs to have a communication policy in place, make it well known and USE it.

Often called a double. Usually ends up with a mess that is incomprehensible. Sometimes it's unknown and unavoidable, but it's one reason you should pay attention to other traffic around.

I've gotten labels put on the front of my GMRS radios with the call sign, so its visible when they are speaking into the radio. That might be an option. I used this guy: https://sites.google.com/view/kc8gl/anytone-call-sign-sticker He can make custom labels. If you place your radio on a scanner, and send it to him, he can measure and make one for whatever you wanted.

Also, on an HT, you never really get an accurate measurement. Sure, it comes with the ground plane plate to attach, and it helps with the measurement, but you end up using adapters, etc. and it never shows accurately. Rotate or tilt the radio 10 degrees and the readings change. BTW, on an HT, you shouldn't worry about SWR, if the antenna is the correct band split for your frequencies, just go with it.

Also keep in mind, a JPole antenna is not omnidirectional, it has a lopsided pattern. You may be able to rotate the antenna in place to get the pattern to point towards the repeater and reach it better. A mobile radio will be a better option overall though.

The propagation of the radio waves. UHF can bounce off the atmosphere giving you a longer "line of site" distance. This happens more often where there is a large temperature inversion (commonly noticed as heavy fog).

Not really, its extremely controlled, but typically anywhere between 500W and 2000W, even some go up to 8000W, but very controlled. You have to remember, the shielding in an MRI room is to keep RF out to get a clean picture, not to keep RF in. The typical 100db isolation is enough to keep wifi, bluetooth, cell phones and other RF out of the imaging, but the RF does leave the room.

I would hope that a decent 1/2 wave antenna in your attic to a 45-50W radio on both sides would get you there.

So you are saying, in your house you can reach your dad and brother in their house with HTs? If so, a simple attic antenna and decent mobile radio permantently installed in both houses will be plenty.

I wonder if it could be radar, though that should stop at 450, but you know, the feds do whatever they want. Also could be a 2nd image of 925.225MHz, but neither would exactly explain the issue around both locations. Edit: 925 is part of the LTE band. ATT did just have that huge problem last week. It is possible that their outage included firmware updates for the cell tower equipment and now something is out of band/creating an image.

It is the one CHP uses (or was going to). They are available, but not necessarily a stocked item. Kenwood will make them in batches though. I know some guys were working on a few things with those lowband decks.

I believe the NX-5600HB now can do P25. Looking at the XG-100LPA, it was only certified for 16K0F3E per the FCC grant. I did find the manual for it though, and it was an RF sensing. I see one option is use a MiniCircuits broad band amp that will take the 9mw up to maybe 2 watts then use a Tricom RAMP-25 to put out 25W, but I don't know if anyone has said anything about how to key it, or if it will work with with receive audio. I've looked a low band (I am interested in at least listening to see what is out there), but in actual application the mobile antenna is going to be huge and narrow banded to be effective.

This is one of the reasons that GMRS and Business/Public Safety radios are required to meet technical specifications for spurious emissions (Part 90 & 95). GMRS is pretty far away from the 70cm ham band. In fact, 70cm ham is co-located with plenty of other users (US military, radar, unlicensed transmitters like weather stations), that ham just has to deal with. There are plenty of public safety/business users between the top of the ham band (450) and GMRS, that GMRS is one the least likely to cause issues.

My TK-8150 radios were the 450-500 split. It did work down to 440.00 while complaining. I never checked power output that far out.

I use a pipe flow slide rule that I use quite often, its a handy tool. Anyways, the more I re-read Part 95, the more I find missing definitions, and what seems to be the intention to prevent phone patches (which don't really exist anymore). The intent of the ruling is to keep Part 95 completely within Part 95, avoiding telecom rules, microwave linking rules, etc., which now the moving target is ISP/IP based connections for linking. The problem is the rules (which seem even outdated for 2017) don't actually convey the intent as a rule. I still maintain that short distance linking via purely RF staying within GMRS frequencies is likely permitted.

Putting it in conduit also helps protect it from weed eaters, rodents, neighbors, etc.

Yes, I tuned my duplexer with the PC app, and turned the resolution up as high as it goes (refresh rate takes a hit, but its not an issue). I then took it to a friend that had the shop equipment, and it left his bench untouched. You are likely looking at very small changes to be made. You can move the screw less than half a turn until it pops out one side, then move it till it pops out the other, and end up in the middle of those two locations. It may be as little as 1/8 turn or less. You do, however, get the concept and did a decent job for a first go around. Will it work as tuned? Yep.

The level of isolation is pretty good. It looks on the top side that you could align the the cavities a bit better, they should show only 1 combined dip. Similarly for the bottom, it appears only 1 of the cavities needs aligned with the other.

Correct, meaning the addition of "other networks" was to include VOIP phones, and not limit the definition to copper pairs.

Funny, right in the definitions: § 95.303 Definitions. The following terms and definitions apply only to the rules in this part. Network connection. Connection of a Personal Radio Services station to the public switched network, so that operators of other stations in that service are able to make (and optionally to receive) telephone calls through the connected station.
