I’m treasuring my multimode, single band transceiver of
yesteryear. They really ‘don’t make them like that any more’. When the FT-790R
was manufactured, the UK still happily built cars that broke down and
industrial action was a continuing popular pastime. Thank goodness the Japanese
manufacturing success story was at its zenith.
In my previous blog, FT-790R,
1W of Forlorn Hope?
I outlined my trepidation, my dreams and anticipated
joy of achieving hilltop 70cm SSB contacts over phenomenal distances. This was
in the face of an antagonist old-timer who thought a little too much RF had leaked
into CPU of my head. So what was the reality?
Since taking delivery of the ‘790, I’ve managed to test most
of the functions. With a radio of that age I shouldn’t have been surprised that
the front panel illumination bulbs have long since ruptured their once-bright
filaments, probably in the early 1990’s. A simple removal and refit of the
battery tray, which holds eight ‘C’ cells was required to reconnect the

Straight away, I connected a spare telescopic antenna for 2m
to the front panel BNC and gave a call on FM. I enjoyed two great local
contacts with stunning audio quality. Excellent audio reports came back too. Two
quick tests with local station John GW4ZPL confirmed that SSB was working fine,
albeit a little off frequency with his TS-2000 shack-in-a-box. Then we tried CW
(my first CW attempt, ever). Apparently John hadn’t heard ‘chirp’ like mine
since working Russian stations in the 1980’s! Luckily the operation manual
comes with a full schematic diagram. I’ll have a look and see if a key click
filter is misbehaving, for example.
Realistically speaking, I do
know that a random 1W call on 70cm SSB is unlikely to attract an
answer under normal conditions. My plan was to get to a modest local hilltop
with a small beam antenna. If there was any tropospheric enhancement or lift,
all the better. Unfortunately, the Welsh weather of late prevented this.
Following the advice of Tim, G4VXE
a competition evening would give me a fighting chance.
Casually having a chat on D-STAR the other evening, someone
mentioned that a 70cm activity evening was due to start in around half an hour
at 20.00. No time to get up a hill and where the heck was my BNC to SO239
adaptor when I needed it to hook up my homebrew 9 element beam? So, if you can picture
me leaning out of the upstairs window with a small, non-resonant, telescopic
antenna pointing out at a jaunty angle, then this was my big chance. My only chance, so far.
I scanned the SSB portion of the band. Nothing. I twiddled
the telescopic antenna and re-scanned. Nothing. But then, a quick call in a
clipped English tone and a GD (Isle of Man) callsign. After a couple of failed
attempts, antenna adjustment, more leaning out of window, the received signal
came up to 5,9. The other station adjusted to my offset frequency and SUCCESS!
- Gave me a 5,4. He said he was using 400W and a 23 element beam that wasn’t
even pointing my way. The distance was around 73 miles or 117km, admittedly mostly
over a great sea-path.
He’d been calling out rather robotically but had a
chuckle and warmly wished me 73 when he heard about my operating set up. I
forgot his callsign in the excitement and my bemused YL heard a whoop of joy

For every person that has told me that an FT-817ND would be
the ideal rig for me (and it would), there has been another that has regretted
getting rid of their FT-2/6/790R. My FT-790R is a solid, brick-like joy to own.
When I get up to a hilltop to try it out again, I’ll be supremely hopeful!
