I search the internet and found quite a few replies on forums about increasing the dismal Cobra Cam 88 modulation as set by the factory. But, no one stated how to perform the mod- go figure. The mod is simple. Cut the resistor out of circuit at the Dyna Boost switch. All done. The factory stock...
I bought a used FT-726R for 2 meter & 430mHz SSB. Paid $300. Radio arrived and it did not work oin FM. It is doubtful I would ever use FM, but did not like idea of a partly broken radio. I would also have to find amps to boost signal from 10 watts to 80-100 watts. Seller refunded me.
