I could see this being a good deal for someone with limited space per say, like a spot to add and external amp. You could sWAP out the transistors couldn't you and replace them with a set of ones that are used in newer HF radios couldn't you? Or is this not possible? Just curious. Whether they are work well or not I think will be determined by the person installing it. a well setup antenna at 150 watts is 3 times the power total. Granted a well setup antenna system and 50 watts, vs. But it may be enough to get you over the pile I suppose. Like someone posted, it's not even a 6db gain. One word of caution! DO NOT USE THE STOCK RADIO POWER CORD! GET ONE OF THE DUAL FUSED HEAVY DUTY ONES.For the power gain of 100 watts, from the needed 40 to 50 watts to drive it, totaling 150 watts, it might not be worth it. This, added to a nice variable modulator mod, makes a nice, strong, good sounding rig in a single box. Also driving it with less than 40 watts will definitely extend the life of the 150. Want a strong signal for just driving down t5he road in a compact package? It will do ya.
Even then, from what I have seen, it won't do 150. Palomar, thre manufacturer, states 540- watts as what's needed to drive it.
Whats a rfx 150 upgrade#
Even if the radio had a MOSFET upgrade and is seeing 40 watts PEP BEFORE the 150, unlikely you'll see 15o watts. Bad news, you will probably NOT see near 150 watts. It's a pretty solid unit that work well and can give you decent output without a separate box for an amp. It is driven by the finals already in your radio. It just doe the "connecting" inside the radio chassis. Just like an amp it connect between the radios output and the antenna. Unlike it's smaller cousin, the RFX 75, it does NOT replace the finals in the rig it is attached to. In all honesty your RFX might push your signal 1 db over a stock Cobra 29 to the individual monitoring at 10 miles. If you run a good antenna such as a Wilson 1k (or a 102 whip if you aren't putting it on a semi) and had the antenna on the roof of the truck with a low 1.5:1 SWR, and as long as skip wasn't heavy, 10-15 miles could be doable. Your antenna height, placement, SWR, propagation, etc. Stick it in a cubby hole and all bets are off.Īs for talk range.again that too varies. Also a determining factor is if you have enough air circulation around the RFX. I can only wonder if it would play havoc on fuel injectors and such.Īlso if you run it in your truck, you might want to run it straight to the battery as it draws some amkps and the trucks stock wiring may not be adequate enough for the demand.Īlso agree how hot it gets depends on how it's driven HOWEVER you can buy a mini fan kit thru Magnum that sticks on the rear and helps keep it cool. When I key up my mic, it causes the DVR in our living room to stop recording. I have used both as base units, and aning no amp. Case in point, I have two Magnum radios with RFX75's on them. Yes you can use it in your truck, but as Bashnya said, you may possibly have some interference issues. I agree.for $20 you STOLE it! Heck the RFX150 by itself sells new for $100. Only thing that would concern me is that the extra power may cause some computer circuits to act strangely, but at 100w output (you aren't going to get 150 out of it and no one is going to miss those 50 watts) those types of problems are unlikely. What you will definitely be is louder.Ĭan you use it in a truck? Many do. If you have a good antenna setup and the band isn't buried with skip as it can be sometimes, you can expect more range than a stock radio for sure, but exactly how far depends on many factors. Your antenna system will be the largest determining factor in how far you get out and hear.
Think of it this way: If you put a supercharger and nitrous on an engine without upgrading the transmission, driveline and suspension, how long is it going to run until something fails? Not very.Īssuming that the conversion WAS done properly, how far will it reach? Too many variables to say exactly. The stock wiring just won't hold up to the higher current drain of the new final. Additionally, if the pre-final sections of the radio were not upgraded to support the heavier RF final it is going to cause problems. Heat kills radio components and that thing hanging on the back of your radio IS going to get hot, especially if your antenna system isn't properly tuned. Why all the hate for them? In a word: heat. The RFX-75 and it's big brother the RFX-150 might well be the very worst thing to happen to CB radios since the roger beep. Now do yourself a favor and try to sell it for $60.
