Pete,
Your SX-88 might be a little weak on the 10 meter range since mine does
seem to be fine in that respect. Of course the Kenwood R-599D (and I
believe the A version is the same except for the color) are very quiet
and sensitive on 10. I first used one at a Field Day setup in 1976 and
my first thought was the receiver wasn't very sensitive given the lack
of noise but then a CW signal popped up and it was an eye opener
compared to my much noisier Heath SB-102. I own a pair of the A and D
twins and my only complaint is the transmitter doesn't cover 160 like
the receiver does.
I have a lot of vintage receivers but the SX-88 probably gets more use
than any other even though it is not at the top of the performance heap
but it is certainly competent and fun to use. I rarely listen to SSB on
it but it does a very good job of pulling weaker AM signals out of the
QRM on 75 and does very well on CW. Even if it had been "the last word"
when it was built it still is a very old receiver in today's world and I
am sure my Drake R-7A and both my stock and modified R-4C receivers will
outperform it under tough conditions but for me the SX-88 is a lot of
fun to use. Face it, under really tough band conditions the telephone
is going to outperform any receiver if you need to get a message through
so endless "mine is better than yours" arguments really are
counterproductive. Another favorite of mine is the National NC-240D.
It is a good performer and has a nice look and the interesting
bandswitching for general coverage and ham bandspread. I have several
members of the sliding coil catacomb family (a couple of NC-100X's, an
NC-101X, the miltary RAO-7, a pair of NC-240D's) and they all serve
their purpose.
For my ultimate heavyweight receiver I am in the process of building an
external final IF/product detector for my Pierson KP-81 to give it
better SSB capability and better selectivity on CW. It is the only
non-National design receiver I own that uses a sliding coil catacomb
system for band changes. Mechanically it is very well built and uses a
total of 11 IF transformers in the 455 KC IF giving it a pretty nice
selectivity curve on AM phone. The receiver and its external power
supply/audio output stage/speaker weigh about 140 pounds between the two
units. Part of a recent hamfest haul was a box containing a number of
unused 85KC transformers for the command sets so I decided this will be
an interesting use for them. Adding a Hammarlund HC-10 to my TMC
GPR-90 really changed its personality; I would love to have the matching
TMC adapter but given prices that isn't likely to happen soon.
