    I run this set-up in my mobile with a 2x8 pill amp. I have a 250 amp alternator powering 3 batteries. everything is grounded correctly and I run a Predator 10-k antenna with the thick coax. The Magnum is adjustable from a 1 watt to a 10 watt dead key and swings to around 45 watts. I have a Galaxy 93T that has a 2290 for a final. This radio swings to almost 80 watts with a 4 watt dead key and it works great with the amp.

    I'm wondering if the mosfet finals in the magnum are causing the problem.........I don't know. But I do know power is not an issue because the Galaxy swings higher with no problem. Thank-you for your response......I think I'll sell the Magnum and buy another Galaxy.

    what kind of amp are you using?? Is the magnum stock? whats your dead key? Most amps work best with a 1 to 4 watt dead key if its pushing more than that your probably over driving the amp causing it to shut down.So more than likely youll have to reduce the dead key and that should cure your problem.Looking at the specs on this radio stock on AM it averages 9 Watts RMS and 40 PEP so its probably overdriving the amp. are you using this radio for a base or mobile application? This radio by its self draws 7 amps max. Let me know what you find....Dean

Too much wattage for a 2x8, those are 4watt input max, and wouldnt push more than 20pep maybe the dave mades can take a little more abuse. but certainly not 80watt pep into a two pull driver. for both of thoer radios i would suggest a high drive. btw, i love my Omega Force. I think your problem is the mostfets are near shorting out on those two driver pills.

He said he can adjust his carrier from 1-10 watts. Which is stock. I have an S45 as well, I run it at about 3watts swinging to 30 into a 2x2290 all the time that drives a dave made 4x2879HD. Sounds like you have about the same setup as mine with your 2x4pill. Try turn down (or have it done) your max peak power for both am/fm and ssb to max of 30att and see what happens.

Im a Galaxy man myself and I swear by them .Looks like youve got more than enough power. The mosfets shouldnt have any effect that I recall but be aware that most new C B Radios are going to Mosfets Galaxy being one of them' because of transistors like the 2290 being hard to find and expensive. $20 + a pop.

I have a magnum omega s 45 hp that goes into hyper scan what can i do

Hi don,

Hyperscan is usually, but not the only domain of scanning receivers.

Does it affect your Tx or Rx, if not, then there is nothing wrong, but if you want it to stop scanning for an active channel, then press the scan button once to stop it.

I hope that answers your query.

Wiring a mic

The Delta Force and Omega Force are wired the same way, so if the mic is not working on the radio, check the mic out to make sure it's working. Make sure you have the mic gain turned up on the radio. I assume the mic was not wired for another style of radio??
