Hi there
I wonder if anyone has had a similar problem to this one.   Had model boat down to the lake today; and the transmission range was shall we say 'very short' say about say 20 yards.  I had the same problem last week with a totally different model but same transmitter.   No-one was on the same frequency, and the aerial was fully extended on the transmitter and on the model I had this morning, the aerial runs along the deck for the receiver - and - the model I had out last Sunday (an MTB which the aerial is coiled around the inside of a Carley float on deck ) ,   The MTB (I know for a fact has a range of over 1/4 mile with a Skysport 6 transmitter).  Riggers and I tried this out a few years ago.   Now, came home today thinking the aerial wire may be snapped inside the transmitter - took it all apart - but couldn't find a thing wrong.   No evidence of black wire or anything inside the transmitter.   But, I noticed - when I switched the transmitter on - and removed the crystal from the transmitter - the power needle goes up to 100% - replace the crystal into the transmitter and it drops down to the near enough 60% or, just outside the red bar.   Tried this crystal and other crystals in another Skysport 4 which I have and it stays at 100% same as on my Skysport 6.


So, has anyone experienced this type of problem/any ideas - I still cannot sort the shortness of range - Its as though there is a short when you plug a crystal into the transmitter.   


Obviously I have tried various other crystals in this transmitter, but, they all have the same affect.

The transmitter may have goosed its output stage and gone to join its ancestors.  I'm assuming that it is a long serving one that has been known to work previously, rather than a newly aquired one that hasn't been used previously.
Doing a quick goggle only hit 35MHz ones.............
