WRYT685

I've used CB for emergencies, but in light of the recent AT&T shutdown, I'm picking up a couple more GMRS/FRS HHs for my spouse and adult kids to use for emergency comms if something similar happens to our provider/s. We fortunately live close enough we will be able to communicate on the FRS channels between our houses.

Any clue what would cause one channel (15 here) to sound like an old Peterbilt at high idle? Its pretty regular, and screws with my scan mojo...

Going to my first Anime/Scifi/fanfest this weekend with my adult daughter. She's big into them, makes costumes and everything. What should I expect?

It's already round filed.

UPDATE: One new coax later, with the excess coiled by the air cleaner, I'm getting 1:1.02, mounted on the roof rack.

Not planning on doing any super tight winds; I just spent two hours writing up a Quality Assurance report to Engineering on a landing gear harness with excessive bend radius. As anal as we have to get with the fiddly bits on jets, I see no reason to not take the same precautions on my rig...and we run loads of coax in stacked runs.

You're probably right. Just for the Halibut, I clipped off the crimp connector and used a solder connector...SWR got better by half, but were still 5+, so that coax is getting round filed this weekend. I have a new Midland NMO mount and coax that I'll be putting on, along with a new antenna. Now, for the eternal debate...should I or shouldn't I shorten the coax vs. looping the excess in the engine bay? (not enough room behind the dash/console for a 12" loop) *fight's on*

If you google "MXT275 Owner's Manual" you'll pull up links to the .pdf document Midland puts out. The last few pages are charts that show Channel freq, and tone codes for Ct and DC modes. I had to download it, too, the manual that came with the radio didn't have those pages. Or, you can grab it here, since I just saw the upload tab... MXT275-Owners-Manual-11-16-20 (1).pdf

I think your forgetting one important factor: they were all BELOW GROUND. The EM burst was strongly attenuated and dissipated by, well, the ground. That was by design...the NORK government doesn't go out of it's way to piss off it's sole sponsor, the PRC. Our government learned from Starfish, and applied those lessons to future testing. Exoatmospheric detonations won't be so attenuated, at least for some distance.

That's what Amateur Radio bands are for.

Checking for shorts is the first thing I did. Yes, I shortened the cable and crimped on a new one.

I was loop testing to make sure both the center conductor and the braided shielding weren't broken. It's a common technique in Aviation to jumper a pair of wires/conductors to verify continuity.

More data: pulled antenna and checked for shorts at both ends, because OCD. No shorts. Installed a jumper between center pin and outer connector, got good continuity at the NMO pad end, switched ends, same-same. Resistance measured out 0.9 on 200 Ohm setting. For giggles, I broke out the teeny mag mount antenna and put it on the meter: 1.0 sitting next to the old mount on my hood. *throws papers in the air*

So, I'm setting up my in cab rig for my offroader, MXT275, MXTA26, hood mount for the whip. It SWRs out to 2.96. Pulled the whip up as far as I can, 2.46. Okay, can't add more metal, so did some digging, seems a lot of folks trim it down quite a bit to bring it in...trimmed off a smidgen, 2.35, okay, right direction. A little bit more...WHOA NELLY! 10.7!!!! Put my stubby on, which had measured at 1.0 earlier, and it was 10.6...did I cook my coax with a measly 15 watts?
