- IC-745 - PROBLEM: TUNING COUNTS SLOWLY DOWN
- I have a probnlem with my 745. When I rang Bellevue, WA,
- they said: Never heard of it. My friend in LA who has the
- same pronlem got the same anser. The problem is as follows:
- The tuning counts slowly DOWN whether it's memory or VFO. I
- temporarily used the set by turning the dial in the UP
- direction faster than the countdown and then used the lock
- button when the set arrived on the desired frequency. The
- XIT?RIT can be used for small corrections. My friend who has
- a complete professional lab at his disposal found a
- temporary fix. He grounded pin 40 of the I/O IC which steers
- the CPU. Everything workds fine except that you miss the
- slowest tuning speed and that the UP/DOWN button on the mic
- does not work. I did the same and my set work the same. The
- tuning is a little bit coarse now but usable except you have
- to be careful especially with RTTY or AMTOR. The local ICOM
- repair shop is too busy at the moment with their normal wo4k,
- and I don't like to be without this set for too ong a time.
- I can't use the 730 to drive my linear at least not without a
- lot of trouble. I suspect thqt one of the two transisstors
- has gone but which? I just wonder if any of your readers has
- had the same problem and fixed it. (ED Note: Anyone have the
- solution?) (Thanks, Bob Bartelings, VE6CBN, 170 Haysboro
