It can be easily built by any one and can be powered using a 3 volts battery. 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. RFX 150 AMPLIFIER HOW TO RFX 150 AMPLIFIER SERIES Mosfet Amplifier Circuit This circuit is designed using two Mosfet’s and one transistor which makes it an easy to build circuit. It is better to purchase a radio that has all of the bells and whistles on it. 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. I have one in stock, but it is not for sale. 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. Product Description150 Watt (200 Watt with ERF9530 upgrade) OEM Final Amplifier Section with High Performance Low Pass Filter.Well, first of all, I don't know that much about HAM radio, and don't really care to. The RFX150 is an RF section for Magnum, and other, 10 Meter Amateur Transceivers. The RFX150 can be bought as a replacement part providing a low cost solution to increasing the RF Power of a 10 Meter Amateur Transceiver. The RFX150 does not work independently, but it is an integral part for an amateur transceiver and is available for repair and replacement purposes. the presidency in 2024 The deadly tornado that ripped through Gaylord Michigan Friday had wins up a 150 miles an hour The national weather service says. 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. The RFX-150 receives RF signals from a compatible. COBRA 29 LX RFX 150 INSTALL Well, first of all, I dont know that much about HAM radio, and dont really care to. The RFX150 uses a matched pair of ERF7530 75W RF Power MOSFET from Palomar Electronics. The Universal Remote RFX-150 is an antenna module that works in conjunction with the MRF-350 base station. Unique Vertical Fin Design Maximizes Heat Dissipation. Rfx 150 amplifier - serreowl Rfx 150 amplifier In addition, we show that contrary to the known role of RFX as major regulators of cilia formation 17, in RFX1/3 deficient HCs, the primary cilia (kinocilia) develop, and planar cell polarity is not impaired. 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 inĪ mobile environment you need every advantage possible. ![]() That is why the RFX150 features a radically unique design with vertical upward pointing cooling fins. The fins extend past the transceiver’s top cabinet to allow increased airflow to the heat sink. ![]() Latest Technology MOSFET’s in an Old School Circuit. The RFX150 uses a matched pair of ERF7530 high power MOSFET RF transistors running Class AB. The familiar push-pull design features time-tested components such as broadband transformers and dipped mica capacitors. *ERF9530 upgrade includes installation and adjustment.
