I have a rather nice Pride DX 300 for sale or possible trade for other ham gear...Such as hf radio's etc..This amp produces 800 watts with 15 watts of drive..Fan is a little noisy but have not used it much so i would say it needs some oil...Very clean amp inside and out...Sale or Trade
Thats the problem when i unkey the mike and sometimes when i just power up the rig the s-meter will peg out and make a static noise sounds like its oscillating and getting into the receivers front end..sounds like a lightning storm at times..any adjustment in paticular that i need to check?..Thanks
Have a rather new rci 2970n2 mosfet and it has the feedback suppressors installed but still have excessive current draw like 15 amps on key and 40 amps peak and feedback when you unkey the mike..Like self ocs..and does it as well sometimes when you turn the rig on..the more you use it the less...
Just got it,Won't ever use it i'll just trade it for something i guess..Not 100% sure that it works has been sitting for many moons,But have seen it work some years ago..

the pre driver current to 100 MA as per the service...
Have a 98vhp and the driver bias won't drop under 180ma or so no where near 50ma and the Gate Voltage is around 4.6 and not 3.75 or at least i think that's what the service manual calls for..The final bias set without a hitch..Radio seems to work fine and great reports but something is up with...
My friend just bought a new type with the mosfet and switchmode power supply 2995dx and it has a frying sound in the transmit audio,This is the second one i have seen do this,The first we sent back to ranger and they fixed it they say with an alignment but i am sure there is more to the story..I...
When i say the working 101 needs alignment,when you install new tubes or used you will need to nutralize the tubes and possibly make a few minor adjustments.These radios are very simple to service with the manual..The radio will work with a set of tubes but to get full performance i would...
