Default Re: Hedghog standards converter

I am experiencing an anomaly with the Hedghog modulator, I decided to have a look at the output on my spectrum analyser to see what it was like for harmonics and I worked through the channels from 1 to 6 all was well except Channel 1 which had the Sound at 41.5Mhz and the Vision at 45.5Mhz exactly 500khz out this does not show on any other channels and the clock is running at 4Mhz, has anyone else experienced this or have any idea why this would happen?
When running the unit into a TV it does appear to work OK but tuning is a little touchy compared with say Channel 2 on a Sony 9-90UB.
