The fins are designed to extend past the top cabinet of the radio.įrom one Z-MAN to another.hello. (coming soon).ĥ-3/8" wide (across the back panel of the radio) x 2-1/4" deep (how far it sticks off the back of the radio) x 2-1/2" tall. The RFX150 fins are drilled and channeled for easy mounting of the optional fan kit. Heavy-Duty Power Cord with SAE Connectors and weatherproof fuse holder The familiar push-pull design features time-tested components such as broadband transformers and
The RFX150 uses a matched pair of ERF7530 high power MOSFET RF transistors running Class AB. Latest Technology MOSFET’s in an Old School Circuit The fins extend past the transceiver’s top cabinet to allow increased air flow to the heat sink. That is why the RFX150 features a radically unique design with vertical upward pointing cooling fins.
So why would anyone design a heat sink with horizontal or downward pointing fins? In lower power applications this may be okay, but when dealing with hundreds of watts in a mobile environment you need every advantage possible. Unique Vertical Fin Design Maximizes Heat Dissipation. The RFX150 uses a matched pair of ERF7530 75W RF Power MOSFET from EKL Components The RFX150 does not work independently, but it is an integral part from an amateur transceiver and is available for repair and replacement purposes. The RFX150 includes the RF final output stages and low pass Filter section for a 10 meter mobile amateur 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.The RFX150 is a replacement part for 10 meter amateur transceivers.
Rfx 150 for cb radio install#
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. The above 5 reasons are a few of the most common reason for failing to get good power output after installation of the MOSFET. 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. TIP: Always have a schematic of any radio that you wish to put MOSFET(s) in. 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. 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, 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.
It gives me something to repair later on. Well, first of all, I don't know that much about HAM radio, and don't really care to.
