If you cant get a install for the RFX75 for a Radio that you may have let me know and ill see what i can do to help. So in all without the 68PF cap it cost $20.45 to do up 10 Radios. That is $7.95 cheaper than what you are paying but i buy in bulk to do 10 radios and i don't bother with the 68PF cap. I pay $1.50 per IRF520 and $0.55 for the home brewed EKL EN-1230

Details INTRODUCTION: The RFX75 is a RF final output stage and low pass filter designed as a replacement and/or upgrade for most 10-meter amateur transceivers. PS: paying $10 bucks for them EKL parts is not worth it. My DX 959 is pulling 3 Amps with a 2w carrier and just over 5 1/2 Amps with a 10w carrier when i give it AUDIO on AM it pulls 7 Amps and on SSB it pulling 14 Amps The power cord may need to be upgraded as well to a 16 gauge or better. Just a side note you will need to change the inline fuse from a 3 Amps to a 7 Amps min. this is high from what i have seen from the RFX75 box avg is 50 to 75 but it depends on what radio its going in that will determine the swingįor the Cobra 25 hear is the install for the RFX75 The RFX75 is well worth the 35 to 40 for the power that you will get I have one that i installed in my Galaxy DX 959 and its doing 210w carrier 100 watt swing +or- 5w.
