Dr. FT757GX user!

As a user of the "old" FT757GX, -in fact one of the first models imported, 
several years ago, i had a wish about some improvements. I use the rig, -also 
for VHF/UHF with transverters. For packet-use is the attack-time for the 
squelch much too slow, so i made an simple modification in order to improve 
this function.: 

The simple "trick" is just to change C158 (10uF) and C159 (4,7 uF), both
to 1 uF. They are located near Q22 (MC 3359), and it's possible to 
change them from the upperside of the PCB.: Push in the old capacitors 
with a cutting-tool, -and the lead-wires are left back in the PCB, -for
use to solder the new ones in the same place. After this modification,
-the squelch is now working perfect (and fast) in all modes.

The "internal" PMS-scan-speed is very slow too. I had therefore made an modi-
fication to the hand-mike (Yaesu MH-1) in order to set the "internal PMS-scan"
to "fast-mode".: 

On the backside of the mike, -there is a switch for tone-select. One half 
of the switch is now used for "short-cirquit" the fast-scan-button on the  
mike (pin 4 & 5 in the mike-plug). This simple modification will improve the 
scanning-speed (to fast-mode), - operated from the "PMS-button" on the rig 
too!

Now to a question:

During many years of operation with the rig, -my biggest wish however, 
is to have the dial-speed (tuning) improved. As you probably will know, 
-it's unbelievable slow - and boring - only 10 kHz per dial-revolution! 
(How about using an electric driller - hi hi!). When used in FM-mode 
(on 10 meter or with transverters), -it's even worse!

If any of the readers have some informations about a change to - say, 
- a factor 5 or 10 increase in tuning speed, -please let me now! Otherwise, 
- i'll have to find out of something myself.

Please, -have a nice and funny time!!
