Just to refresh. Optima MK3 power is the same regardless of the jumper setting. And if my memory serves me well... You can change the digits by using the step feature and the mhz by pressing button 2. The TS667 never sounds good on SSB. Best amp for the optima is the TS500 non variable. Hard to...

They are not worth the money when you have new Ham radios for a little bit more. Fiddly and cumbersome to use and a PA section that can go poof at any time. Another 25w CB radio and a Texas Star DX500 will cost the same for double the watts and half the trouble.

In that case the 405V for sure. The fans work fine for me..better some fans than no fans. I have seen way too many problems with the 503 over driving that single driver transistor and I am not even sure that driver is particularly linear. The 503 would be a lot better had they had just dropped...

Better is the KL505V.

The Magnum 257's are made in the philipines and are also sold in Europe under the Albrecht label and downunder as the dragon 485. I am sure Eric could still release them if he saw fit but the screen is a little bit changed now...different fonts. The design is getting old but it is still a pretty...

Well worth the 700 bucks! Mine stays on the bench all the time. Just spend the time to get used to it..and it does take a little time for us kenwood and icom users.

just can't keep everybody happy!! AT5555 is still available but the At 6666 seems a bit more popular these days. There is also an AT5555N. Bigger LCD screen and no christmas tree effects

Don't use the green button at all. Control the output with the radio ...... That's the right way to run an Amp

Now we have smart phones which can talk reliably round the world for free with no external antenna and google maps and Waze can show you in real time where the jams and frequently police are...so who needs a CB radio in their truck? Who needs skip to talk round the world? Put the radios in the...

I have found the FET that RM is using is a little better than the IRF 520 that frequently gets substituted when the RM3 gets overdriven and dies. RM file off the markings so hard to know exactly what the RM3 really is.

If you don't turn the SWR protection off or set it high it has a tendency to kick in all by itself ....All these radios the same. Turn it off and rely on a proper meter to check the antenna.

You can't toggle between 40ch with the channel number showing and full coverage mode on the Optima MK 3 without adding a switch somewhere and some wiring. Full coverage covers all the 40ch CB band in 5khz steps showing the frequency. Just use some of the 5 memories to store the CB frequencies...

It is well protected so just increase the input power till you get your 500W on 20. It wont to that on the higher bands and you will be lucky to get 200w out of it on 10m it should be good for 80w input.

I have cre and president lincoln 2 and mag one mics and all sounded much the same with my voice...Like everything..horses for courses!

stick with the mic the radio came with. Its about as good as it gets for that radio.

get one and stick it in your car and let us know what you think.

If you can get past the strange faceplate of the magnum 1 staring at you then you should have no troubles with the Mag 1. I think it has the best receive characteristics of any CB radio out there right now. Much easier to listen to and no AGC woes that all the Anyclones suffer from. And lets...

Sharing is Caring

Nah..its all pretty quiet. Don't have the money to invest in a new radio right now! Just have to leave it to the experts like Icom and Kenwood and Yaesu!

I believe they all went to South America. Probably Brazil but that's a guess...
