[Heathkit] Sb-110 notes and Ft-620

[radioman]

Just keep the Yaseu... it is a better radio... and I have lived with
both for years.

Under no circumstances should you substitute a 6CW4 for the 6DS4 in the
SB-110 or A.  This will make it impossible to neutralize the front end
 those are triodes remember ).  Despite the ARRL lumping the two tubes
together in thier manuals.. they are NOT the same tubes.. and you will
be miserable and curse the SB-110/A if it has the 6CW4's in it.

Any 6M radio without squelch is a real pain in the +ACoAKgAq-.  Unless you are
plugged into some other alerting system for openings... ( and there are
several)... you will have a giant hot hissing green radio doing
absolutely nothing for days on end.. in hope that something happens.

Remember white noise is a form of torture.

The good news is the fast qsy from a chosen listening freq.. and pretty
good dial calibration.  The bad news is no memories ( in either radio)
so you can't be checking several likely but widely separated freqs fast,
unless you like grinding coffee.

The yaseu has a lower over all system noise, is smaller, extremely
reliable, and has the right power level to drive most amplifiers  tube
or solid state.

The Sb-110/A requires a good deal more periodic maintenance to keep in
tip-top form than it's HF cousins like SB-101.  I far prefer the A
version.

If you can use it when the band is open.. and admire it the rest of the
time.. the power ouput will help.. but it really doesnt hear all that
well in weak signal applications.  The Yaseu isnt rocket science.. but
with it's permeability ganged tuning of all stages... it is a keeper...
just add a squelch and a little amp and you've got something.
