You already have a janky cable connecting the lights and likely brakes to the trailer. I don't see how one more cable would make a difference.

My thought was it removes a great big blind spot.

It also has a Special Feature, so you've got that going for you!

Do you have the older GM 30 or the newer GM-30Plus?

I am thinking to go lugit and get the GM-30 plus. Some of the recent reviews dog it because it is not supported by CHIRP. I opened your link and can not figure it out. Is there a CHIRP update that supports the the GM-30 or did someone just figure out a different profile that works?

You didn't quote the whole text of (a), which does make a difference. (a) Exceptions. Under certain exceptions, non-certified Personal Radio Service transmitters, or transmitters certified for use in the land mobile radio services may be operated. Any such exceptions applicable to stations in a Personal Radio Service are set forth in the subpart governing that specific service. See e.g., §§ 95.735 and 95.1735. 735 is for Remote Control Radio Service. 1735 is GMRS but it's blank (reserved). I'd say that means no exceptions, unless it's hiding somewhere else.

There's enough stuff that can go wrong with towing as it is. I don't know if I'd want to add a janky cable between the tow rig and an antenna on the trailer for the fractional theoretical gain you might get over just having it on the truck which, I'd assume, is where the radio also already is.

Assuming you have enough slack in the coax to allow turning, I can't think of any reason it wouldn't work.

Interesting, QRZ did a review on a Siglent last year but the model they reviewed was $600 bucks.. The review was pretty decent.. I'll got thrugh these and figure this out.

BlueMax 49ers has most of the Kenwood programming softwares. Also, check with Ohio Solo Tech for Kenwood CPS.

No, but I like the idea. I'll report back later.

Pursuant to Part 95.335(a) - "non-certified Personal Radio Service transmitters, or transmitters certified for use in the land mobile radio services may be operated". This means a Part 90 certified radio programmed with Part 90 and Part 95 freqs may be operated/used as long as the radio operates within the power, bandwidth, freq accuracy, and emissions specs of the Part 95 rules for the freq being transmitted by the Part 90 radio. Just in case you do not know, Land Mobile Radio Service (LMR) is Part 90.

Here's a question for the RV set. Does anyone mount an antenna on your trailer and have it connected to your tow vehicle while traveling?

Additionally the GM-30 is now supported by Chirp https://chirpmyradio.com/issues/9237

See attached file for the KPG-91D. So far I don't have a copy of KPG-66D yet in my archive. The install serial is in the archive file. Normally the "E" versions are for European radios and the "K" is for US. Sometimes the "E" unlocks all market versions. The later "K" version may lock you into using narrow band FM. Just have to try it. KPG91D-V2.13.zip Serial Number.txt

You can get a decent dual or quad channel scope from Rigol or Siglnet. https://www.rigolna.com/products/digital-oscilloscopes/1000z/?srsltid=AfmBOoq2bRx15El9ycZvSSCi6OgpdDeIvbIipWFNl2DJeCLXNXmRZwKT https://siglentna.com/digital-oscilloscopes/sds1000dl-series-digital-storage-oscilloscopes/ Myself I have my eye on a spectrum analyzer. Either the SSA3032X or the SSA3032X Plus. https://siglentna.com/spectrum-analyzers/ssa3000x-series-spectrum-analyzers/ https://siglentna.com/spectrum-analyzers/ssa3000x-plus/

The majority of LMR radios do not have free downloads from their sites. Many Kenwood shops will sell yo uthe software. It most likely is on a CD and not a floppy. I'm sure there are places on ebay that sell a download but I've alwasy preferred software from the vendor vs internet

Yes, I see what it says. Chinese vendors (never heard of that one like many others) don't understand English very well or the FCC regs. Just get some more GM-30s from Radioddity. [I don't need the Chirp file because they obviously messed it up.]

Cool. Looking forward to getting the wheels dirty in PA. First week of October is Uhwarrie JJ so will be there for that one as well. We have busy summer with events. SMJI is in August so will be there, then October have 3 JJUSA trips planned and Windrock for hopefully November.

Here is the Amazon link. https://www.amazon.com/gp/product/B0D7PYT1XS/ref=ox_sc_saved_title_3?smid=A3ND7E64AZOQU8&psc=1 It does call it a HAM radio in the title, but farther down in the description it says "Connectivity Protocol - GMRS". If interested, I attached the .img file to upload to CHIRP to see what the frequencies plan looked like when I first opened it up out of the box. Frequencies originally programmed on Baofeng radio.img

A was the old GMRS section; it's Subpart E now. Yes on the antenna, but the requirement is radiated power (ERP), which includes gain from the antenna. So stick with sorry original stubby "rubber duck" antenna for that.

I haven’t looked into this but hopefully they have a software program that can control it from a pc.

Also check out the Radioddity DB20-G a/k/a Anytone AT-779UV mini-mobile: 20 watts, mic controls, cigarette lighter plug, $99-$109 Add a $20 mag-mount antenna and Amazon cup-holder mount and it easily installs/uninstalls in your vehicles.

5 watts vs 2 and optionally external antennas on your vehicles will make a big difference. And of course your GMRS license extends to other certain family members. I often read many complaints about Midland radios on this forum and they seem to be overpriced
