Superstar 3900 GHP 10 metre version

Post by johnkyrle »

Okay,there must be a simple modification to make a 10 metre SS GHP operate on the lower frequencies.I have read that there are two soldered joints on the board and 4 resistors at the front end of the board which need to be removed.Is this correct?Any advice welcome.Thanks :?

think you are thinking about the info on this page half way down with pics
i have only seen one that needed this done and this was a long time ago
but i remember using the info on there to add 10m to a 3900 via a switch early last year was an ept360015c mosfet version
think i had in 4 x3900 last year in and out but were already expanded before they got to me and i dont see many

The best advice would be to send it to Nick Blackspirt he will sort it out for you and it will be spot on..
