Bandspread on CB Board

I wanted to ask the group if after adding more channels to the cb
board PTBM036AOX, can the board cover the band spread. The
coverage in question is about 1.6Mhz on both transmit and receive.
Would this board have to be broadbanded? Zodiac suggested I post
this msg. to the group.

Thanks

Motorola HT90 Charger Problems

Hello all.........

I was wondering if anyone is familiar with the Motorola HT90 charger. I have recently purchased one at a hamfest this past summer, but the charging light
stays on without a radio in it, and I don't see any DC output voltage at the pins. Can anyone help?


Thanks

Led Channel Display

Thank you for responding. Yes If you could walk me through the procedure, I
would greatly appreciate it. I plan to convert the board to 10 meters, but would like to see the mod on this addition of LED channel indicators.
