sorry for not viewing cb's video just yet, but......when rf limited introduced the microphone with frequency change controls, they needed more pins on the mic plug, and the 6 pin plug was an rci item, so they went with a uniden 8 pin plug. it's actually wired the same as the ft757gx2 i once owned. there were 4 & 8 pin versions right up until the end, never saw an 8 pin (factory) 3300, not sure they ever used one. also have never seen a factory 100w 3300, only 3500's. the face plates of the 3300 & 3500 are not interchangeable without replacing the freq span buttons underneath the display because the 3300 used vertically oriented rocker buttons and the 3500 used 2 individual momentary pushbutton buttons. neither are very durable. whoever the factory got those 2 types of buttons from used a very poor quality item. both types are unique to these radios & unless you find a junker, you will not find a replacement. there is no other chip that will go inside this radio, it reliably covers 12m through 30mhz, albeit via a 'soft' mod by reprogramming the cpu through the front buttons. at that point you can only change freqs by the scan control, dead/no battery, or going too far & causing the radio to lock up requires disconnecting power(and battery for lock up) which becomes a nuisance. it will work with the jumper mod, just 26mhz is as low as the jumper mod goes. let nobody tell you otherwise, a properly tuned ar3500, 30 or 100 watter, with the original speech processor is a SCREAMER on AM and SSB. no question about it. sure you can go overboard & crank the 2x2290 amp up to nearly 200 watts, and you can destroy the stock audio-which sounds far from stock to begin with-just leave it alone! it smokes my ic706mk2g in any mode from 12-10. the biggest complaint with these radios, after all factory updates, was ACR. bleedover can be nasty at times. this radio is NO magnum. nor rci. nor stryker. this is a super version of a uniden 8719 chassis, using a cpu instead of pll and different mixer freq then the uniden. adjacent channel rejection was the only miss. tuned side by side to factory specs, the ar radio outhears & outtalks the xl-type radios hands down.
i have one 100 watter & 3 30 watters......original owner of the 100 & 1 30 watter. and 'rod, either summer of '07 or '08, during E-skip season, you talked to my 100 watter on a 'particular' freq. 125 watts on AM through peak E skip season, pegged needle noise....pegging your needle with a mere 125 watts.
