Terrible you are having all these issues. I apologize for giving you hard time before. I thought you modified the radio with larger finals for more power. I am sorry. I will say this though. I heavily modified my RCI2950. I never modified it for more power. As I upgraded components I kept the...

Well non-rf mosfets suck for making rf and are not tolerant of anything. As they get hot they creep all over the place with power output, with stability, and their swr's change under load really really quickly under load as freq. and temp climbs. The trick is turning the power down to 1/3 what...

Don't want anyone left behind. I have used this for years. They used to be sold on ebay but not now. It is actual much cheaper now that it is not on ebay. When my old home made one I built in middle school on bread board died I found this. I do not do hifi I went the opposite route long ago. I...

The reason I like nice flat audio response is so that you are not fighting the natural tendencies of the mic to color your sound with artifacts from it's design. This means you are in control of what sound you get via processing. Since stock CB's have rather restricted audio to begin with the...

If you look at the factory certification I posted inside the black inked box bottom left it tells you that the supplied results were achieved @4V. I do not have documentation for them so I do not know the upper limit. So blocking cap and resistor. I do know that the Gentex mic element I run in...

It is just like any electret mic just like the tiny ones people toss into D104's. You run power up the mic cord. Only this is much larger thant he tiny elements most use. For none hifi or non-eSSB I would just use a much smaller and cheaper eletectret like what are used in cordless phones, cell...

Science only works when it is measured, repeatable and predictable. Science only works when all questions are fair game! Science and engineering should almost always produce results in the rear world if they are mostly true! If it is a sometimes, never maybe situation maybe it is not ready for...

I checked them out on my DER EE DE-5000 LCR and it showed them being 100% within specification and I cut one open to make sure the polymer was black and shiny still and it looked as it should! I always check capacitance and ESR before I use any caps even though I buy 90% of my caps from Mouser...

So I was going through caps in my stash for my Cobra 138XLR the 25V 4.7uf caps all I have is computer grade/audio grade solid cap. They are still technically an electrolytic aluminum polymer but the electrolytic portion is a solid polymer. They are Sanyo OS-CON's. My guess they will work fine...

Some days it is so hard to just look away and keep on walking past a good deal you do not actual need! I know I am in good company though on this site! Cheer's to my people! :p:D

Primo 6-111693 Microphone NEW W/ B&K CAL CERT!! It Bruel & Kjaer I have been using these for years. I posted about them a few years back. I think I have still have 4 new in the box. I think I paid between $24 to $36 back when I first posted about them. I found them on Ebay and they still have...

I don't own anything that uses them but I have some on hand. You never know what might come up for sale on the used market so back when they first came to market I bought some 9530's and some 2030's. Learning from my mistake with the all the bipolars I should have stocked up on but failed to...

I had an RCI2950 from 1991 to about 1998 then it was stolen. I first noticed dimming on transmit so I changed and upgraded the voltage regulator which helped but did not solve the problem. Then I found that the crystal filter was bad. That solved the problem. So the problem was the crystal...

This is one of the reasons why you will see guys running 2-3 amps daisy chained then feeding into a huge 32pill or more transistor amp or monster 10 LDMOS or tube amp setup's.

Yes I know I even mentioned my pet radio has low level modulation and no mistaking it. My point was that you need to start off with a radio that has the characteristics you desire. I was pointing out the obvious difference between the different types of modulation circuits and why it...

I am sure we have all seen the prices of radio's the last 2 years especially sky rocket. So I was on our favorite online auction sight just looking for general parts and accessories. I almost had a heart attack when looking at mic's I used to give $20 to $30 for NOS selling $200+. I have 16 or...

Well hopefully one of those people that actual know for sure will chime in! It has been 9 days.

I thought for sure when I took it out of the ebay box it would either not work or work poorly. When it worked so well I thought for sure it must have been recapped already. Nope. It was shocking to open it up and find a time capsule. This was very well cared for by the original owner. I guess...

By "loud" I think what they really mean is very dynamic and punchy audio. Most of the audio giants are radio's based off of cybernet chassis designs with high level modulation and darlington style modulation circuits and plenty of audio bandwidth potential. The export radio's have more...
