Well, first of all, I don't know that much about HAM radio, and don't really care to. It gives me something to repair later on. Well, I know where the calibration screws are in my meters and in 2 seconds I can make a radio with a stock 2078 do 75 watts, it all depends on if the tech wants to stay in business or not, I've been doing this for 30 years, so.īut, I do enjoy reading some of the hilarious posts on these forums, and I love the guys who read this stuff and then try it.

I buy 2078, 2166, 1969 finals by the bags full, they are hard to find, but, when you find them, USE THEM !Īnyway, the meter has everything to do with it, that's the dividing line between honest tech repairs and lies, I see a lot of lies, especially the one where some repair guru said, "Yep, she's doing about 48 watts right now". Well, the main issue here is, MosFets are NOT designed for use in standard CB radios, the list of excuses why it didn't work can go on and on until the next ice age comes around, but, as long as the tech got paid for what he did, oh well right, I hear that a lot, and I see a lot of cobra units on ebay, with blown MosFet upgrades, it doesn't have to work. TIP: Always have a schematic of any radio that you wish to put MOSFET(s) in.
COBRA 29 LX RFX 150 INSTALL
If you continue to experience problems with power output, In the long run it may be better to have an experienced technician install and tune it for you, that way you can be sure it will be done right. The above 5 reasons are a few of the most common reason for failing to get good power output after installation of the MOSFET. Not properly retuning radio after installationģ.- Not changing coupling caps when requiredĤ.- Not using the proper companion bias chipĥ.- Not retuning your radio on a 50 ohm (non inductive) dummy load Proper installation of a MOSFET will increase your power output.īottom line is this: If you install a MOSFET and do not see a big improvement in wattage output, you are doing something wrong, possibly one or more the reasons below:ġ. It has absolutely nothing to do with what brand or model meter you are using, or even if you calibrate your meters every day on a lab standard.
