Probably the same as one of the several known features on other 5RMs. Just because the radio can do something, like scrambling and frequency hopping, doesn't make it legal to use. Stick to the basics - we don't need a lot of these new features being added to radios.

It's exciting. Almost like getting to the prize in a box of Cracker Jacks. I can't wait to find out what it is.

There aren't any exceptions specified in GMRS Subpart E for LMR/Part 90. The things you list do not authorize other services; they are just limitations on GMRS. The examples given are references for 2 selected services, not all services in Part 95, that's why it's e.g. There's nothing I can do to make anyone understand what the wording means - you either get it right or you don't.

Those "certain exceptions" are the power levels, bandwidth, allocated frequencies, frequency accuracy and stability, and emission types as listed in each Subpart for applicable frequency being operated. Those rules/regulations are the certain exceptions. In other words, you can operate your Part 90 type-accepted radios on 462.5625 MHz with certain exceptions. Those certain exceptions are: if you do not posses a GMRS license, you are regulated to narrowband emissions and at 2 watts ERP pursuant to Part 95, Subpart B; and if you do posses a GMRS license than you may use either narrowband or wideband emissions and not exceed 5 watts ERP pursuant to Part 95, Subpart E. And if you operate on 154.600 MHz, you will be regulated to the aforementioned exceptions in Part 95, Subpart J. There, those are your "certain exceptions" Yes, there are references to Rules 95.735 & 95.1735 in Part 95.335(a) however, they are only references, and not the context of the subject rule, did you notice the "e.g."? Do you know what the "e.g." means when used? Part 95.1735 was an old rule that more than likely existed prior to the 2017 rewritten/reorganization of Part 95 rules. Obviously, the reference of 95.1735 has been overlooked in 95.335(a) in the editing process since it no longer exist. You said, there are "No Exceptions". Where does it say "No Exceptions", it says under certain exceptions and those certain exceptions are stated in each subpart in respect to the frequency being used pursuant to the respective subpart.

The older GM-30.

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.
