Edit:

I got my hands on two new in box 75-160 handhelds.  They are FM, and the channel frequencies are:

Channel 1 - 27.095 MHz FM
Channel 2 - 27.145 MHz FM
Channel 3 - 27.255 MHz FM

The FM deviation appears to be 5 kHz.  I checked using a multi-norm handheld set to the Poland band plan - AM/FM CB and was able to hear 27095 pretty much loud and clear on 27.100 MHz Channel 12R.  Same with 27145 coming in nicely on 27.150 MHz Channel 16R. 

Channel 3 is indeed 27255, CB channel 23 and I was able to hear RCRS data bursts on it.  Apparently a single-channel variant the Midland 75-150 FM Walkie-Talkie was also sold.  It advertises 1/2 mile range just like the 75-160 3-channel 27MHz FM walkie talkie box does. 



So I went on a bit of an eBay binge, ended up ordering a Maxon 49-HD 49MHz 5-channel FM walkie talkies and RadioShack TRC-512 / TRC-503 5 channel 49MHz handhelds, 27MHz paging transmitters (RadioShack PG-80, and Command Communications PrivatePage PS2000AN pager - which is similar to the RadioShack PG-99 pager 17-6020)

…and pair of Midland model 75-160 3-channel 27MHz FM Walkie Talkies. 

FCC ID F9GRC-3000 F9GRC3000

These indicate FCC Part 15 compliance on the back of the radios.  3 channels, indicated as 1/2/3 on the side of the radio.

FCC type acceptance date is 13 June 1991  - formatted as 1991-06-13.  FCC rule Part 15C, Grant Note 37.  Operating frequencies 26.96 MHz - 27.27 MHz. 

FCC Grant Note 37:


I found a thread on an Italian language forum about it being a “civil band” or “urban band” (CB radio) walkie talkie with 2-4 km range and it likely operating on 27.120 MHz.  Nothing is said about the 3 channels. 

https://www.elforum.info/topic/98890-statii-portabile-walkie-talkie-midland-cred-ca-destul-de-vechi/

Since these aren’t 49MHz handhelds and they’re FM mode they are intriguing to me.  They appear to be early 1990s vintage. 


One thing is the operating band for 27MHz Part 15 has changed very slightly over the years.  Now it’s 26.96 MHz - 27.28 MHz.  Old versions are 26.97 MHz - 27.27 MHz, 26.96 MHz - 27.27 MHz, etc. 

26.960 MHz - 27.270 MHz is the one that matches with this radio.  I know 15.227 is the same as 49.82-49.90 MHz in that it’s 10,000 microvolts/meter at 3 meters. 

These radios are listed as 1/2 mile range radios, which to me says more than the 12 microwatts or whatever 10,000 uV/m at 3m is.  Seems more like a 50mW to 100mW type rig…like the old 100 milliwatt single channel RadioShack handheld CB rigs TRC-91 or TRC-92 and several others. 

On another tangent, these could be turned into legal 11m 27MHz Part 15 beacon transmitters.  A blurry image of the radio’s PCB clearly shows a set of 3 crystals and another set of 3 crystals, likely a transmit/receive pair for each of the 3 channels. 

Once the radios arrive I’ll figure out what channels these things are actually on.  Since the operating band is 26.960 - 27.270 MHz, I’m assuming some combination of the RCRS channels…26.995 MHz, 27.045 MHz, 27.095 MHz, 27.145 MHz, 27.195 MHz and 27.255 MHz.  Avoiding 27.255 would make sense but who knows. 

Since it’s Part 15, in theory, it could be any 3 frequencies in the 26.96 to 27.27 MHz range, 27.120 MHz, 27.240 MHz and 27.250 MHz or whatever. 

Hopefully I’ll be able to update this thread with another piece of 27 MHz walkie talkie  history.  Now that FM is legal on Part 95 Class D CB radio, regular CB channels would be okay, but the RCRS channels are better for a potential beacon project. 

I’m interested in knowing what, if any difference in the associated Part 15 section 15.227 (47 CFR 15.227) in effect when these radios were approved. 

Also, what does this mean? Grant Note 37

FCC Grant Note 37
FCC Grant Note 37 signifies This device has shown compliance with new rules adopted under Docket 87-389 and is not affected by Section 15.37, transition rule

Here’s FCC Docket 87-389

https://docs.fcc.gov/public/attachments/DOC-342985A1.pdf

Does anybody have a copy of Part 15 as it was in 1991?

Listening via the W3HFU SDR, and also locally.

Heavy fading at 1820 UTC tune in.  Nice loud FM deviation. 

Faded down into the noise for 3-4 seconds at 1823 UTC...then faded back up to SIO 222 or so.  Even at a S-3 signal strength level, readability is...meh.

Signal strength jumped up dramatically for a few moments at 1824 UTC and then dropped back down.

The Latin American land mobile radio systems and freeband 11 meter CB operators are starting to pop up in the nearby spectrum 25-26 MHz as well.

At least right now, 25950 FM 25.95 MHz FM 25.950 MHz FM is nowhere to be heard.

Bumping an old thread because I stumbled upon some of these 3-channel 27MHz FM walkie talkies.

Midland model 75-160

FCC ID F9GRC-3000

FCC Rules Part 15C

Approved on 13 June 1991

Operating frequencies 26.960 MHz - 27.270 MHz

https://fccid.io/F9GRC-3000/amp

And Google Translation of a post from an Italian forum thread about them:

They low-power citizen band (CB) stations, with a range of 2 ... 4 km, work in the 27 MHz band (most likely 27.120 MHz).

Usually, the date of their manufacture is written on the electrolytic capacitors, so the station must have been produced approximately in the respective period. By all appearances - types of parts, design, way of making, etc. - it can be a model from the mid-90s

Note, I changed the formatting from 27,120 MHz to 27.120 MHz. 

Since they’re 3 channel radios, and the main PCB clearly shows two sets of three crystals, presumably a pair of crystals for each channel, one transmit and one receive, with the 455 kHz TX/RX difference. 

The channel selector simply says MULTI-CHANNEL

1
2
3

I’ve read that they use 26.995 MHz, 27.045 MHz, 27.095 MHz, 27.120 MHz, 27.145 MHz, 27.195 MHz, 27.250 MHz, 27.255 MHz and 27.270 MHz. 

Use of the RCRS channels would make sense.  Some sources call these 100mW output radios, others call them 50mW.  They remind me of the 100 milliwatt (actual output was 50 milliwatt) RadioShack single-channel CB walkie talkies like the TRC-92 and I know there were many many others. 

Sort of intrigued.

Canadian military airport CYSD radio beacon, transmits "Y S D" in Morse code followed by a tone burst.  Similar format to a NDB or VOR type station.  No tone (does not have the usual 150 Hz tone squelch that military FM systems usually have - that usually decodes as 151.4 Hz instead of 150.0 Hz). 

It's FM, but comes in great in AM mode as well since its just modulated CW.  I believe its a 1000Hz tone, but I could be wrong.

I haven't heard it in many many months.  36.600 MHz is the frequency.  Strong FM deviation.  36.6MHz CYSD beacon YSD beacon 36600.0 kHz FM

This signal appears when the band is open to points east of the remote receiver I'm using (which is in the UK).  So it could be from Europe, the Near East...or any number of other places.

While there are dozens of active paging systems on right now, this one is unique, or there are just a half dozen signals on top of each other at once.

Typical POCSAG paging signals with 3-4 kHz bandwidth, 8 kHz bandwidth, others with 10-12 kHz bandwidth.

The "idle" (constant) data signal is a MFSK data signal 6.5 or 7 kHz wide.  Center frequency.   There appears to be an amplitude modulated part as well, and a carrier or pilot tone.  Currently two signals, with pretty typical very small offsets from the center frequency.

27940.05 kHz
27940.15 kHz

I will try and get some video and audio recordings of the signal.  There's a lot of weird stuff on the 25-30 MHz band (yes, including non-ham stuff within 10 meters) and 30-50 MHz (I know, there's another forum for that).

Hearing both locally on a handheld radio - a PNI HP82 (PNI Escort HP 82, Jopix CB-514).

Hearing UK stations calling CQ and US stations replying on 26.805 MHz FM 26805 FM at 1450 UTC.  Noted US stations at 1445 UTC.  Several other out of band frequencies active, including truckers on 26.735 MHz AM, 26.755 MHz AM.

US and UK stations working FM on CB Channel 27 FM.  27.275 MHz FM.  Some SSB QRM and AM QRM on frequency.  Good sounding FM signals.
