When new my Scout had backlash. When tuning down in frequency to say
14025.5 kHz and then reversing direction to tune higher the audible
pitch AND the display indicated that the frequency continued to tune
lower in frequency by about 100 Hz or more (14025.4 kHz) before tuning
higher to 14025.6 and above. I consider that to be a form of
backlash as I would loose play in the tuning (which the Scout does
I returned mine to the factory and listed this as one of several
problems in the Scout. Their apparent solution to the backlash was
to clean and lubricate the guide rod. Upon return there was an
improvement, but the backlash is starting to return after two to
three weeks of moderate use. Tuning is a bother on both CW and SSB
... I like to be on frequency, because the other station is more
likely to return my call.
The nearest International Shortwave Broadcast Station is over 30
miles away. I have International Shortwave Broadcast Station
interference on 20m using a 3 element monoband yagi (very much
resonant at 14 MHz) and on 17m using a 3 element dual bander for 17
and 12m. Also the interference does not appear to be from the
nearby station. In my case the interference is at 14027 and 14195
kHz and I like to chase DX. When time permits I will try additional
filtering in the antenna lead ... at least this is probably
correctable without too much effort.
Even the factory readily admits that the Scout is a compromise, and I
think there is probably a concensus by owners that the compromises on
the PTO were too much against performance as opposed to cost. After
point of sale correction in the field is also more challenging in the
case of the PTO.
If K5KVH does not have problems with his PTO he is indeed fortunate.
