Paul,
Your "Substance" is flawed...If you want real substance, I'll give it to you
and it does not support your insistence that the 706 has a noisy receiver.
Perhaps your neighborhood is noisy.
The following are the specification for both radios for a "10db S/N" ratio:
IC-706 FT-450
HF .15 microvolts .2 microvolts
6M .12 .16
VHF .11 ------
This would lead one to believe the 706 has a better receiver.
End of subject. Its time we moved on to more fruitful discusson.

Carl,
I think I got mine from Parts Express or Allied Electronics. Both
have good selections of the lithium disk batteries with the solder
tabs. You may be able to get a battery locally and solder your own
leads onto it, but these batteries can explode when heated.

But that will lead to a noisy receiver. That kind of
sensitivity isn't useful on the HF bands, where the
atmospheric noise floor is above that, and so is the
man made noise floor. Most sensitive doesn't always
mean better. Selectivity plays a big part in receiver
performance, as does the front end and blocking and
IMD dynamic range. The amount of noise one hears is
also dependent on how many IMD products the receiver
is generating in a crowded band.
I think QST measured the 706MKIIG noise floor with the
preamp off around -138DBm, which really isn't useful
in real life conditions because the typical noise
floor most of us have when an antenna is connected is
around -120DBm or so. The rest of the sensitivity
just comes thru as noise.

I would guess that ANY battery will explode
if severely overheated! Having said that,
I have had good success soldering directly
to NiCd batteries. The secret is to preparing
the surface well. I scrape the surface well
with a sharp knife so that more surface is
available. Use a 63/37 solder, a HOT tip
with quite a bit of mass, then get on and
off quickly. The shell of the cell then has
plenty of time to dissipate the heat before
any damage occurs.

John, you're right, and I'm pretty sure the 450 bested the 706MKIIG by a
wide margin in dynamic range. I have only dial-up here at home and can't
check the ARRL reviews, but that's my recollection. Perhaps someone can
post the numbers.
The 706 series are great radios but there are compromises.

John,
The 706 noise floor was measured at:
minus 138 to 136 with Preamp off and minus 142 to 140 with preamp off
The FT-450 noise floor was measured at:
minus 126 to 107 with preamp on and minus 136 to 114 with preamp off.
The 706 provided much better noise floor numbers under lab conditions. This
would imply that in real life situations the 706 should be a quieter
receiver given the same antenna setup and QRN/QRM additions.
As Paul has pointed out "The 706 series are great radios but there are
compromises."
I find that any small package has its compromises. You can only get so much
blood from a turnip, but the portability for mobile use makes either radio a
nice addition to complement the home station. The main drawback to these
little jewels is the small knobs and too many menu driven functions. Makes
for tricky operation doing 70 mph on the Interstate highways.
To some extent I support both radios. I tend to lean toward the 706 because
of the VHF bands and the fact that I have some on-hand experience with it.
However I still prefer my IC-735 and fortunately I have room for it in the
Motorhome. I may be a little partial to Icom because of the reliability
that I have had with the 735 for the 22 years that I have owned it. On the
flip side my Yaesu FT-920 fits very nicely in my home operating desk. I
think its among the nicest radios Yaesu has built. So I basically support
both brands. Each has its Pros and Cons.
