Morrow SSSB-150... how to program this xcvr?
 

I bought n old Morrow SSSB-150 39 ch. synth HF marine radio and wonder if
anyone has info on how to program it. Is this rig from the company in Oregon
that made the early ham mobile gear and later got into Lorans? Never saw any
Morrow marine HF radios before this one. Thanks, Mark

I haven't seen one of those things in 20 years. Very rudimentry SSB
Radio, that had a bunch of flaws. Peter Hopp was one of the designers
of that thing, before he left Morrow, and went to SEA, and learned how
to design Marine Radios the right way. Don't load the Tx up to max
or the Amp will melt down, right in front of you.

Good Luck finding any doc's for that thing. They didn't make very many
of them. Less than 200, if I recall.

Frequency stability was only +/- 1 PPM. Not legal these days.

I blew the dust off the shops old Morrow notebooks and found a "service"
manual for this radio. It is poor quality Xerox at best with schematics. I
haven't had time to review it in depth, but all I found in a fast scan
regarding programming was a list of HF SSB stations that looks way, way out
of date.
Yes, it was the original Morrow Company who made it, now part of ArNav I
think. IIMorrow came about later by the sons of the Morrow founder. The
were bought out by United Parcel Systems after a lot of money thrown away
trying to produce ACSSB commercially. Remember when US hams lost most of 220
MHz to that fiasco? Anyway, UPS uses the former IIMorrow to make GPS
tracking systems for their fleet and I believe the aviation part has since
been acquired by Garmin. At least some warranty for Garmin goes to Salem, OR
for aviation stuff.

IImorrow started out with loran vehicle location equipment. It kind of
worked.
The ACSB equipment was built by SEA and they were responsible for the
220 band being acquired for it.

What's wrong with 1 ppm?

1 PPM is 1 Hz/Mhz Figure at 26 Mhz your now at 26 Hz plus or minus
Now the spec for modern MF/HF SSB Commercial Radios is +/- 20 Hz, so
you out of tolerence on frequency.
Not good enough to meet current Type Acceptance Spec's.....

Hi Bruce,

Yes I understand the spec. But as far back as I can remember ssb being
used for marine applications the spec has been +- 20 hz. That was even
before synthesizers came to the market.

So I would guess that if the radio was specked at 1 ppm that it
probably did not cover anything above 20 mhz?? Probably only covered
through 16 mhz?

Regards
Gary

I have no recall of SEA being in the ACSSB push, but know for a fact
IIMorrow was, and ran employment ads every few months in the Portland
"Oregonian" for ACSSB engineers and technicians until shortly after UPS
acquired them. I know, as I submitted my resume in the late 80s. Perhaps
Bruce can address SEA involvement. I seem to recall IIMorrow was a
petitioner to the FCC for the 220 MHz frequency allocation which claimed it
was an unused amateur band in the Oregon area. In their area, back in the
50s and possibly even early 60s, 220 MHZ was unuseable due to military
preemptive use for the old old Nike missile system used to defend
metropolitan areas. The long since closed Camp Adair SAGE site and Mt Hebo
radar site were part of that system in the area.
