The TQ3419 cable, is that the one that's RIBless? No programming interface required?
If so, that plastic block in the midle of the cable contains the RS232 to TTL level converter, essentially that IS the interface box.
I don't have that exact cable, I have the keyloader version of it. Which also works as a programming cable, which is good as I don't have a keyloader.
FYI, my cable's part number is RPM 2472/36 R1A
I do like playing games with the backlight LED colors. Boredom can lead to stupid ideas.
It also helps to differentiate my personal radios from those used by and owned by the county and
other agencies. The TX/RX LEDs on my "main" 7100IP are blue. In retrospect, I should have left the
TX LED red. Then, in encryption mode, I'd have purple. (For those who don't know about it, when
the radio is in encryption mode, both LEDs light during transmit. This gives orange on a stock radio.)
I can't say for sure but I think that any version of ProGrammer that supports the 7100 will support the
UHF low split 7100.
Your personality revision 31 indicates the radio was last programmed with version 17. (Revision minus 14 equals RPM version. For RPM-programmed radios, 50 means RPM v. 1, 51 means RPM v. 2, 52 means RPM v. 3, etc.)
The UHF low split radios are simply a problem if they're not in the band you need. Conversion is not
impossible but it's not exactly easy, either. For starters, the TX-RX switch/filter unit sticking up out of
the top of the board has to be changed out. And, they are a massive bear to change. Unsoldering
it is hard enough, and the pin holes are so small that it's very tough to suck the solder out. I end up
using a drill bit to drill the solder out, by hand. (No power drill, just a tiny little brace and bit.)
If you look at the UHF manual, you'll see that a LOT changes besides just the TX/RX filter unit.
Frankly, I see those UHF low split radios with nice feature sets as a way to put their nice feature
set into a radio in a better bandsplit that is lacking in good features. Swap the ESN chip and the
feature string and you're done. But be gentle. If you break the ESN chip, you are most definitely hosed. I suggest using only a hot air gun to solder/desolder the ESN chip to avoid placing mechanical
stress on it.
