Unfortunately, this data is just about meaningless!
What good is a report which says the noise floor is
of such and such a number without specifying exactly
what IF bandwidth is being used during the test? Saying,
as the RX-340 data does that the "SSB" filter was used
is absolutely meaningless: there must be 10 or more
useful SSB bandwidths available using the TT 340;
exactly which one was used????
The same can be said for most of the other data presented.
The "wide spaced" dynamic range info might be
perhaps meaningful at night in Europe, rcvg signals across
a very crowded International Broadcast band where
multiple 100 kW station are spaced every 5 kHz or so, but
not very meaningful in amateur radio use, hi. Of all the
rigs listed, only the Collins 51S1 and the Ten Tec RX-340
were tested for this spec listing with signals spaced 100 kHz--
wonder why. Most of the others are listed using only
20 kHz test signal spacing..... All this stuff is really of no
use, hi.
If you care to buy some of their other material, you might find
explanations of meanings and answers to the "whys", but
as presented...not of a lot of use, at least in my opinion,
but who am I???

On Kauai, where it is a Looong way to anywhere else besides
other Hawaiian islands! We need great rcvr's out here. Our
closest signals, after about 300 miles from one end of the
inhabited island chain to the other, is about 2500 miles,
and that is to the California coast line. NYC, 5000 miles;
JA, 4000; S. Africa, 12,000; VU, 7800; Sydney, 5000;
Israel, 8600; Peru, 5900; ZL, 4600.........you get the
idea. The Hawaiian archipelago islands are the most
isolated of any other in the world!
