I know nothing about this equipment so please don't ask!
Repeater-builder is looking for additional info on the Regency and RELM repeaters,
bases, mobiles, etc.
Photos, like those of the K500 scanner below, would be appreciated.
|Regency Electronics was an old-line electronics manufacturer from the 1950s and
1960s... I still have an early Regency TR-1 pocket transistor radio, and a MR-series
tube-type tunable VHF monitor tabletop receiver from about 1961 or 1962, both of which
my dad brought home one evening... he was a commercial photographer then and was doing
some work for an article on Christmas holiday electronics gifts for Popular Mechanics
magazine. The Regency representative gave him two of the items after the photo shoot
was finished. A number of years later I found a matching tunable low band receiver at
a neignborhood garage sale. All three still work perfectly today. By the 1970s Regency
had low-end land mobile equipment in their product lines, both VHF and UHF, plus some
amateur VHF and UHF radios. The Civil Air Patrol had been using them, under the Regency
brand name, for many years at that point.
Regency's last consumer product lines included programmable scanner receivers, including the "M" series, which were the first synthesized scanners that covered the amateur 10 and 2 meters and 440 MHz band without mods, and advertised as such. A programming trick appeared soon after in the Radio Communications Monitoring Association (RCMA) Bulletin on how to get out-of-range frequencies into it, like 52 MHz amateur radio channels.
In the late 70s Regency bought Wilson mainly for the Wilson-designed mini-handheld that was 1/4 the size of the existing Regency equivalent product, but left the Wilson HF and CB antenna line intact.
Later on Regency Electronics abandoned the consumer electronics market, and today the name is unknown, except as the first two words in Regency Electronics Land Mobile, better known as RELM.
Nowadays RELM is fully in the land mobile business, and has bought Uniden and the Bendix-King land mobile product line (BK kept the Avionics products). RELM did not abandon the BK or Uniden names, both still exist as if they were separate companies.
But the Regency Electronics name is, unfortunately, forgotten except by a few.
Don Pies, one of the founders of Regency, has his own page.
You can find documentation for RELM's currently supported models here.

radios can be acquired from

| Regency ARU9PL / TRU-152A radio Service
Manual 2.7 MB PDF file
This is the 15w two channel crystal controlled mobile radio that was built into an M-series scanner case. It was manufactured either for 450-482 or 482-512 MHz, and range changing is difficult to the point of being not worth it. The radio was shipped with crystals for either 465.500 transmit / 460.5 receive or 494.500 transmit / 491.500 receive pre-installed and pre-aligned, and the oscillator design was so poor that the designer had to use clip-on heaters on the crystals to maintain frequency stability. A CTCSS tone board was optional. The design was fairly fluid, there were at least 7 versions of the main board.
| Programming info for the Regency XL 2000 UHF radio
Repeater-Builder received this note in March 2014:
Regarding the programming info for a Regency XL2000 UHF radio: it starts out with putting a jumper in place then watching the display. This is impossible because the XL2000 does not have a display! It is a diode matrix programmed, sloped front, UHF radio with only two channel capability, and the second channel is ususally the simplex of the repeater pair programmed as channel one. The RF output is 15 watts and it does have an onboard CTCSS encoder, but I'm not sure about a decoder!

| Regency M-400 scanner owner's manual
4.2 MB PDF file
This manual covers the 40-channel model, the M100 is the 10-channel version. And note that the radio only actually lets you enter 30 channels into the scan memory, and while the VHF search increment is 5 kHz the UHF one is 12.5 kHz (i.e. it can't do either 6.25 or 20 kHz spaced channels).
One trick with the Regency M100, M400 and K500 scanners: As shipped the advertised frequency ranges were roughly 29.5-50, 144-174, and 440-512 MHz. You get an error message when you try to program a frequency outside those ranges (for example 52.525 MHz). You can defeat the scanner's preprogrammed frequency limits by entering an additional decimal point first, for example, to enter 52.525 MHz you would press the keypad in the sequence of (dot)52(dot)525(enter). If the VCO will lock the scanner will accept it (if it doesn't it displays "Poor F."). The only side effect of this trick is that if you have an out-of-band frequency in the scan loop it steps to that channel, then hangs until the VCO sweeps across to and locks onto the frequency. The slower-than normal slew rate causes the scan rate to pause for a amount of time as the VCO gets there. I suspect that this out-of-band feature was included for production line test purposes. One acquaintance of mine that picked up a M100 at a garage sale (for one dollar) loaded 52.525 and 8 six meter repeater frequencies in it and is quite happy with it.

This manual covers the base station version of the M400, the K100 is the bare-bones 10-channel version.
The "dot trick" from the M400 (mentioned above) works on the K500 model as well.
