So many memories...
It's almost literally a true statement that I've owned at least one of every Motorola FM two way radio product shown in these photos, and more that I haven't seen in these photos.
Somewhere I have a photo of just my portable radio collection when it alone was over 80 radios. (Of multiple brands, but mostly Motorola.)
I had Motracs that were old enough that they hadn't transistorized the receivers yet. (Later Motracs only had a tube transmittter.)
I've had HT200s, HT210s, HT220s, HT10s, HT90s, HT440s, MT500s, pretty much everything newer....and really learned quite a bit from the MX series, which I say is the radio series that really made a technician out of me. I thought those were the neatest radios of all time (up to that point in time) and they taught me a VERY important lesson: Flexible circuits are supposed to be very reliable....but once they get flexed enough, they're the worst nightmare to troubleshoot and repair of anything on earth.
There was a German made Motorola mobile radio that was very interesting. It was a slim, compact dash mount radio, which internally was an MX portable with an added higher power output stage. They turned out not to be so reliable..
I saw and got to play with more interesting "SP model" MX radios than you can shake a stick at. Some really interesting ones, like a fourteen
channel UHF MX before the advent of the synthesized Scorpio (MX-300S) replacement for the legacy MX. Fourteen frequency channel elements, TWO offset elements, too. (One for simplex, one for 5 MHz repeater split offset)
I rebuilt and reconfigured more MX radios than I care to remember, including doing 48 channel conversions on Scorpios. I had a cheat sheet listing all the common parts combinations to order for any given reconfiguration.
The first 5 channel 800 MHz MX-300T trunked radio, with DTMF front, no less.
The incredibly rare MX310 size MX chassis is still on my bucket list. I had every other size, 320 to 360, but never have yet found a 310 for sale.
Out of all "vintage" radios I've ever used, if I have to pick the few that were the absolute standouts in terms of performance and reliability, for me it's the Saber for portable radios and the Syntor X (or X9000) high power drawer unit. (110 watts vhf) I never had a failure of one and they always out-talked every other radio.
I had a Syntor X installed in my car and with the 3dB gain Spectrum antenna I ran with it, I could talk simplex over 40 and 50 mile paths if the guy on the other end had equally good equipment. It'd bring up repeaters at full quieting at ranges in excess of 120 miles if the repeater was a good one on a high antenna site.
