I always found it interesting that cb amplifiers and their customers want variable power. Except for ldmos amps, ive never seen this on any commercially available amplifiers. People should control the amp with the radio not the other way around.

My biggest complaint about all the brownings, is while they sound good for what they are and they're fun etc I've only ever used the one two and three, and all three of them did not have a very discerning receiver. I could usually hear a couple channels wide and it was really fucking annoying

I wonder if thats the case why people aren't using them on the bowl, or at keydowns, or in hi fi setups... I mean all of those different niches are used to spending money. I mean look it's like owning a classic car, it's cool and it's fun and I'd like to have it but I know that I'd get angry...

Ill give you about tree fiddy for it.

A 50watt 148?? Good lord diamond jim! Id like to see that! Ive never seen one do more than 20 and that was a blown out mess. Mine does 18 and I'm happy

A 1 or a 2 pill. That box will produce 2-2500 pep easily. Use as much drive as it takes to get there. Likely 10% of its output. Probably 100-200 watts

Another option, one i used to do, is use an ac fan. It will be powered by the wall current off the main switch. They will not slow down.

Itll be ok

They are 7812 regulators. The problem is they are being asked to sink alot of power without a heatsink. Remove them. Power the fans from The switch.

What is the issue you are trying to resolve? Does the box run?

Thats fine. When u key it it will drop down

They used to float at 18-20 and drop to 14-16

Paging @Crusher

Mgs4u should be able to sort u out

So just an update. Earlier this year after this thread was posted. I put an old stock wilson roof mount on my truck with a sirio fighter p-5000-pl. It had the fold over lever thing. Seemed well made. Tuned very easily. I check my SWR every day as a normal matter of course. Its the first thing i...

What is the swr on 1, 20, and 40?

Id just buy a set of Penta

What is the swr on 1, 20, and 40? It sounds like you just need to retune your antenna

Any single coiled cb antenna mounted on the vehicle roof in the middle will usually tune to around 1.2-1.3 : 1 swr. Antennas without a coil will usually tune to slightly below that to maybe 1.2- 1.1 something. Impedance when measured on an mfj or something will usually be 37-40 ish ohms. If...

Couldn't have said it better myself. I know why ameritron still built with them. From a commercial perspective its a familiar part, its still produced, and somewhat affordable. It also has a pile of other issues like huge long wires inside of it that you need to engineer yourself around. A week...
