Hello Moleculo: Impressive article there showing the before and after HF Band Spectrum Measurements, of EMI from the clone power supply. Good going. Had a ham type power supply generate a noise on a local UHF Repeater frequency, the EMI signal drifted in and out of the monitored frequency. A...

Hello 399: The 10 Gauge wire will be just fine, as it will be insignificant as compared to 16 gauge wire for the tuning. I have made Quads and repaired Moonraker Antennas, and have noticed that the 14 gauge wire over time will stretch. I had some 10 Gauge enamel wire and used it as a quad...

Hello Jonney9: Good going, your parts look good. What type of matching circuit are ya going to use, or do I just need to tune more often? Good luck. Jay in the Mojave

Hello All: Great info and pictures here. Not much can be done for a direct lightening strike, but precautions can be taken. While servicing radios on top of a local mountain top over looking the Southern California area, I noticed a new tower being installed, and the installation crew was...

Hello MOGVC: Well that's the point I want to make is for the radio manufactures and designers to come up with a hot little advanced radio, with all the right stuff in it. They could market the radio with easy add on modifications and such as a replaceable RF Front end with way better noise...

Hello All: What I want to see in a new radio is a great working noise blanker and DSP in the IF and audio circuits. A receiver Attenuator allowing you attenuate the received signal in say 1 dB, 3 dB and 6 dB steps. Sharp IF Crystal filters that allow you to squeeze the received...

Hello cjruger: One of the difficult things about antennas is taking a good picture of them. Its hard to see your antenna in the trees, but if it works great! Suggestion if I may. I have heard of a lot of guys mounting a mast in the tree tied down with rope to have the antenna above the...

Hello All: Anyone have any info on this radio? I have a new truck and need a CB / 10 Meter radio that does all. I have a few of the old Lincolns and they work great, one is even modified (by Bill Good) with a 50 watt PEP output that kicks the Texas Star 500 to new heigths of field strength...

Hello All: Well that's a shame about the mixing problem, hope they can fix that. Have a neighbor that has the CRE8900 radio in his small car and it sounds and operates very well. The home page shows the radios construction, but you can't go by the pictures no doubt. Jay in the Mojave

Hello All: Any updates too who has the CRE 8900 Radios in stock now, July 2013??? Jay in the Mojave

Hello Gunslinger 338: Get the 7 element beam working first with the existing elements all the same diameters first, I suggest. Then try a larger diameter driven element, it will have to be a few inches shorter than the stock element. But when tuning the yagi beam, leave the elements along...

Hello Gen Slinger 338: Yes it can be done. I have converted a few of them into a Crusader 10K Beams. But get ready for opening a can of worms if you don't document your work correctly. That is the antenna will no dough need a few adjustments along the way. You will need to document the...

Upate: Here is a great paper on the Balun, and its uses. http://w2du.com/r2ch21.pdf The Book Reflections II is well worth the Doe Ray Me. Jay in the Mojave

Hello Office 888: You first sentance is hard to follow. What are 2 x 239 fittings??? The SWR will be high just laying on the ground. This is not a good SWR test. Its a know fact that dipole antennas as most all antennas will change SWR when the heigth is changed. The SWR will change...

Hello CDX007: The Penetrator 500 made by Hy-Gain is a great antenna, who can argue that. The penetartor 500 was the result of years of testing and experience at Hy-Gain. Now be advised I have to fill in here as I never worked for HY-Gain or got to talk to any of their design engineers...
