Super Star 3900 GHP

Hey guys, I purchased one of these radios new recently. I did one of the mods posted on CBTricks.com to expand the frequency range. I'm having trouble getting the swr's down and it transmits poorly. I had it plugged into my Wilson 1000 mobile that worked fine with my other radio. I also pluggged it into my Antron 99 base antenna with poor results. The modification went smooth, I don't know what to look for next, any ideas? Thanks in advance.

    I did the extra channels mod that you use a switch and connect pin 12 and 13...to get 28.300-28.500....it doesnt work...well....it works if you put the band switch on F....instead of D...and it's like having the I band...weird

Can't help you there. It's most likely that you screwed the modulator up by extending the frequency range. I used to work for Galaxy and I know what happens to a radio when amateurs try to modify them (no offense). If you modify a high power radio such as your Super Star, you're bound to have modulation and SWR problems. In expert advice, never do amateur radio modifications to a high power radio. If you want a more versatile radio, get a Galaxy DX 2517 CB base station. The DX 2517 has PA/FM/AM/SSB/USB/LSB/CW modes, and bands A-F, and a frequency range from 25.615 to 29.205 MHz. The Galaxy DX 2517 has modifications that can be done right at the factory, they are optional however. The only thing I find annoying with the DX 2517 is that it's bulky, it leaves no room for any competition. When it was designed, the engineers left space saving out of the question.
Anyway, Good luck
and
Best Regards,

On my radio I need the settings for the knobs because other people can hear me but I only get static and cannot hear them. Thanks

Band should be E Band high/low button on high 10 khz off AM selected
To check that you have done this correctly frequency counter will read 27.185 plus or minus 5 khz. This is of course proved you have a radio that is converted for 11 meter cb frequencies.

Check the mike plug to make sure that none of the wires have broke off.I would also check the mike cable with an ohm meter.
