Success! Looks like I may have not been transmitting with the correct offset! I manually input a repeater pair, and got a successful (though faint) signal check response. Excellent.

I've just ordered a programming cable so I can go ahead and program in my local repeaters more easily. But, at last I know the radio is working. I appreciate the help and patience everyone!
 

that's the direction i was thinking as well, just trying to turn the train of thought into something coherent.
i suspect the base programming on those uv5g will be similar what shipped on my Btech gmrs50x1, channels 1-22 were the 7 low power simplex frequencies (1-7), the 0.5 watt FRS frequencies (8-14receive only on mine), and then the 8 high power simplex channels (15-22).  Slots 23-30 were set up for repeater use, with the +5.0mhz transmit offset baked in, though they used the same receive frequencies as 15-22.
if i have a local repeater that the output is 462.575, i'll be able to hear it whether i'm on channel 16 or channel 24, because both receive on 462.575.  However, on transmit, channel 16 is transmitting on 462.575 as well, while 24 will incorporate the offset and have me transmitting on 467.575 (which is where the repeater is listening).

 

Actually, my favorite is a magnetic base with an NMO mount. Then I put a Comet 2x4 or some other quality antenna on it. 

The only other thing I can think of is the transmit frequency. The repeater channels receive on the same frequencies as 15-22, but transmit on 467.xxx MHz channels.

Here is the difference between the 2730A and 2730B for those interested.

I'll have to listen for those.  Thinking either DMR/Trbo, or P25 as likely possibilities.

Yeah, with the shape of the ground plane of the trunk (dependent on vehicle and frequency), I'd expect some directionality, given most will have more ground plane to the sides than front to back. id also expect the greenhouse to be blocking/shading the signal in some directions too.
It just struck me as a little odd that permanent mounting in that location would mean more loss than a mag mount in the same place, where on the roof it's the other way around.

You know, having seen that graphic many times, I just noticed a couple things I hadn't before. First, there's no rating for a hood lip or fender mount, just a mag mount. Second, the permanent trunk mount is actually rated more loss (-2.8db) compared to a mag mount on the trunk (-2.1db).

I absolutely agree. 

I mean, not really a surprise at that size, but I appreciate that they rate it honestly.

I recommend that you add @Socalgmrs to your “ignore list”.  Life gets better.  
Personally I prefer to have a link to the CFR page on the internet rather than capturing a point in time with PDFs:

while there's been lots of valid points raised already, I'll mention something I noticed looking at the specs for that glass mount...wouldn't 1.5dBi effectively be negative gain antenna in the real world? (dBi vs dBd and all)
that aside, I've absolutely run into auto glass on newer cars impeding the signal, which would be an issue with that glass mount inside as well.  aside from the mentioned "hatpin" (uhf 1/4 wave, which are quite inexpensive), Midland's "ghost" (MXTA25) antennas seem to get decent reviews, and that would be fairly unnoticeable hard mounted on the roof without compromising ground clearance (they're less than 4" tall).

For those finding this thread in 2025, Chirp-NEXT now supports editing channels for the KG-805G. No settings for now. It's new support, so still proceed with caution and have a backup using the original software just in case.

The other link was from before a pretty big site/forum upgrade, I suspect things have shifted around a bit. They're also in the menu in the top right, under the "browse" submenu, at least on mobile view.

I guess I've been lucky product wise, but both times I've ordered from Radioddity, I've gotten solid gear (a DMR handheld, and an HF transceiver), but shipping was the issue.
One order got hung up because they shipped DHL to my PO box, the latter was like $50 cheaper for a bundle with some good extras, and said they had us stock, but it shipped from China anyway and took like 3 weeks to get here.
The couple anytone at779uv I've bought (from Amazon, twin to the db20g) have been solid also

I have two Xiegu G90 radios. The first one I bought directly from Radioddity and I won the second G90 in Radioddity's 12th Anniversary raffle back in September. Both radios work great and shipping was very fast both times. I had a technical question and their customer service was very quick to answer my question. The G90 I purchased was one of their bundle deals that I just could not price match anywhere else.
That being said, I will buy from Amazon or other venders that have better customer service and better/easier return policies when possible. And I am will to pay up to $20 more for the peace of mind. Now if the difference is closer to $50 or more is a different story.
I have paid 10-20 dollars more for amateur radios by ordering from DX Engineering, Giga Parts, and R&L Electronics over finding the same radios elsewhere. Those three companies have great customer service and easy return policies.
I avoid eBay, especially for amateur radios since there is a good chance that you will get a Japanese or European version that doesn't work on US amateur radio bands.
 

Sometimes paying a few extra dollars is worth the peace of mind.

@OffRoaderX (aka Notarubicon) tested this myth on his YouTube channel and found that looping the cable didn't affect the SWR at all. That prompted me to test it myself with two different pieces of coax and three different radios from 5 to 35 watts, and I also found no change at all in SWR or transmission range. I'm about to put an antenna on my truck and I plan to leave a few extra feet of coax so I change the position of the radio, plug in an HT, or whatever else may come up. I'll just coil the extra into a loop and secure it with cable ties.

How about trying a company dedicated to antennas?
https://theantennafarm.com

Like Steve said, Antenna Farm, or Arcadian.com, Pulse/Larsen, any of these should have NMO mounts for the Larsen NMO-27, which is a far better antenna than your Tram/Browning.

Interesting. Ive never seen anoy one bash antenna farm on RR. As a matter of fact they are recommended quite often. They did some changes last year but still one of the best places for hobby folks to get stuff. I use Talley and Tessco for work stuff but get alot of non work items from Antenna Farm.

IIRC, they used to be separate, but Rich got them standardized a year or so back, and they SHOULD now be the same login. However, the login doesn't carry over between the main site (where the map and repeater list live) and the forum.

Thanks for the help, got it going!
 

As a added note, concerning Anyone choosing to purchase the 935H, I noticed yesterday it apparently has the Same Problem the FIRST edition of TID H-8's with the battery discharging a Shock from the Positive battery contact, while transmitting !  While holding the 935H in my right hand touching the Battery Contact, I felt a Zap or charge while transmitting ! ⚡ FYI.  I'm going to Call buytwowayradios.com on Monday and tell them this occurred and see if they know about it.
