... The 100D was really bad. I dream of finding a good tube type from some
little lady that has one stuck up in the attic... Geoff , thanks for time.
I will copy these down you gave me. It will make going to the Hamfest that
much more fun. I'm kind of scared of Ebay but that might be a way to go
too. Is the old Yaesu ft101 or maybe ft102 radios worth a try? I see a few
of them here and there.
Isn't the FT-100D the same as the old Tempo One? Any of those old
vacuum-tube-on-circuit-board rigs are pure junk, particularly the Tempo One
and the old FTdx series. Same goes for the consumer junk that was
manufactured in that era. Almost inevitably becomes noisy and intermittent
after a few years use due to the heating-cooling cycle of the hollow state
technology.
Actually, the FT-101 series isn't half bad as a transmitter, except that it
generates spurs on 160. They can be modified to produce good audio, and I
have seen a few of those rigs with the capability of modulating in the
vicinity of 150% positive. But the receiver section has very poor dynamic
range. It is full of intermod and goes belly up in the presence of strong
signals, even at the other end of the band. I would recommend using a
separate receiver.
One thing though, the FT-101ZD is not one of the original FT-101 series.
Those rigs have AM capability, but the receiver, while much better than the
original FT-101, has no provision for an AM filter, although one could
probably be shoehorned in. The ZD is a stripped down version of the FT-901,
which was a fairly good rig, but the AM on it sucked, and those rigs had a
very high failure rate. I used to do the warranty work for Yaesu amateur
and commercial 2-way equipment back in the early 80's.
