I had one of the new ones, and I set the radials at 105 inch per instructions. Using an analyzer at 10 feet above ground, the best I could get was 5.8 SWR. The radials on mine where they clamp together with screw clamps were super loose. Tried double clamping with no change. DX Engineering...

https://www.rfparts.com/sd1446mq.html Matched set of four new old stock for $179.91.

What does the toggle switch on the back do?

Only type of filter that has worked for me to tame alternator noise is the CB60 by Cornell Dubilier. Still new old stock around. https://www.rfparts.com/cb60.html

I bought one, and I think the best I could get was 5.9 on 11 meters. And it was tested 10 feet above ground with an analyzer. Pretty sure the cause on mine was the radials were very loose, and there was no way to tighten them any further. DX Engineering returned all my money, and paid for the...

Europe has been in my radio all day here in Western NC on 11 meter LSB.

His signature is there. I have to click on the "Toggle signature" to be able to read it.

@unit_399 I heard you this past Monday evening here in NC. You were talking to 850 in Pensacola, Florida. You were S7 on my receiver. I heard you say you were on a four element, and on a barefoot Cobra radio. Tried to call you, but I never heard you again that evening.

I bought a DX Engineering coax stripper for .405 coaxial cables. Then bought a used RFC Industry crimp tool from Ebay for $20 shipped. The coax strip tool works great. I have used the strip tool on LMR-400 and 8U with good success. https://www.dxengineering.com/parts/dxe-ut-405c-p1

Then that radio has been modified. Properly tuned with a 75 watt carrier with amp on, that radio should swing true PEP around 30 watts or so into the amp. I know I had the same radio that was properly tuned.

Lafayette SWR and Field Strength meter is what I would have bought. You can still find them on Ebay new in the box. They were sold under different names, but I can't remember which names. The one I bought, new in the box, is spot on measuring SWR with two different antenna analyzers, MFJ-259...

On the other hand, I have experienced just changing radios will make the amp happy with the same length jumpers. For what ever reason, I have had more trouble with high powered radios causing problems. Hook up my Cobra 142 GTL, and problem goes away using the same length jumpers. And on high...

Western Electric is back in business making tubes. Supposedly, some time this Summer they are supposed to be making popular in demand tubes right here in the USA. Story linked down below. And they have a website too. https://www.westernelectric.com/...

Use a pair of small cutters to cut them out, or you can de-solder. Picture below is from post #2. https://www.worldwidedx.com/attachments/20200112_235525-jpg.33307/

Yesterday evening the NE corner plus parts of the mid west were in my receiver all night right up until midnight when I turned the radio off. I am in western NC.

My 2016 withstood some big winds up to 70 MPH. Just right after a year of ownership SWR would spike just for an instant randomly. Traded a local amp builder the antenna for some amp repair. He took it apart, and it had loose solder joint that just fell apart when he touched it. He made a...

The reason builders don't use CPU processor paste is because that they are too dam expensive. Super Lube thermal paste is $14.28 for about 85 grams(3 oz.) on Amazon. MX-6 is $11.99 for eight grams.

The MX-4 was good stuff, so I am sure the MX-6 will be good too. I use the MX-4 on CPU processors, and I still have a partial tube. I have a small container of Dow Corning 340 white paste that I use on everything else like electronic ignitions and etc..

@Brother DXer Good QSO! You are the first one I have heard in weeks. Conditions were not good though. I heard you, but did not have any signal. Pre-amped you to an S6, and I could hear you very good. That Stryker always sounds very good!

I have a couple local friends with the 5555 N2, and they are spot on frequency talking SSB. Their radios have not been tuned/aligned...just converted. Skip was rolling heavy here in NC yesterday evening. Heard three different 5555 N2 radios, and they were all just a tad slow on transmit with...
