I'm in agreement with everything Gary says. I also like the
3-point-something khz SSB filter for ECSS work - SSB is quite usable after
the BFO has 15-20 minutes to stabilize (initially, it is nothing but
warbling..). I also like the continuously-variable RF gain, which makes
passive phasing of locals easier, as I can knock them down a bit to find
the null. The 910 khz images can be annoying, but would not be an issue
out at the beach. My synch doesn't have a muffled sideband - not sure how
common that is (or maybe they both are muffled, since regular AM mode has
noticeably better fidelity...).
Yes, the 7600GR has "real SSB." There is a switch on the side of the
radio to select USB or LSB.
The smallest discrete tuning step (and display increment) is 1 kHz.
There is an analog SSB fine tuning control wheel that permits very
clear reception of SSB for such a small portable. It actually
receives SSB better than a 2010, because the latter uses 100 Hz
steps, but on the 7600GR the SSB fine tuning is "stepless."
Here are some other pros/cons of the 7600GR:
- Very good build quality (made in Japan, believe it or not)
- Selectable sideband sync detector (not as good as that on the
2010, Sat 800 or E1, but still useful to reduce selective fading
distortion or interference)
- Couples very well with the Quantum Q-Stick (I believe Gerry Thomas
designed the Q-Stick for use with his 7600G, which preceded the GR)
- 100 memories (10 pages of 10)
- Sound quality is somewhat muffled on AM (especially compared to
the E10 or E100)
- No tuning meter (only a "Tune" indicator on the LCD)
- No tuning knob (just fast/slow buttons -- 10/9 kHz or 1 kHz on MW,
5 kHz or 1 kHz on SW)
- One side band is usually more muffled than the other in sync mode,
as delivered (this can be adjusted fairly easily)
I hope this helps.

Thanks for your comparison of the 7600GR, the E10 and the E100.
Very interesting. I'm still looking for a small spotting receiver
and I know that Gary DeB really likes the 7600GR. Could you help
me out by describing a couple of things:
Is the SSB on the 7600GR a "real SSB," allowing the selection of
USB or LSB???
What tuning rates can you use to tune across MW in SSB??? Please
be 0.1 kHz as one choice :>)
