I would imagine it is on Roger Birds page but any one that has worked on CB's can do the mod. You have two mod's one improves sensitivity and spurious rejection the other protects the front end from over load if you operate in or around a lot of CB'ers running a lot of power or live near an...

What where you hoping for??? A tube is a more complex version of a light bulb!!! You do not break in a light bulb do you! You have metal wire with coatings on it that take a given amount of power. They radiate electrons that get picked up and carried into the circuit in a given manner that...

That is what I was planning to do but wanted to make sure that sounded right! Given that HV transformers do not grow on tree's I do not want to mess anything up! As always I am being very safe!

Yes MRF477's are expensive and hard to find and a lot of the stock floating around is counter fit junk! My Lincoln has the MRF455 if ever you pop that MRF477get some perf board and do the MRF455mod much the way the factory did it. Then follow Roger Birds tips on replacing the driver and...

Nothing wrong with those amps in general. All amps have compromises in them some place to make it to a given price point! Why? Because a lot of people do not have a lot of excess money or they do not wish to spend a lot for their hobby. Not everyone has to die with the most toys or the best toys...

Really Guys and Gals??? No one can tell me what they did to cheapen the design of the D104M6???? I was told by one old timer over the air years ago that they replaced the crystal mic element with a cheap electret mic element like radio shack and Cobra used and they also went with cheaper...

Google Baluns as well then take that idea and what the other's are explaining and it will make it a bit more clear. The Library near you might have the ARRL's guide to antenna's and it is fantastic for explaining all of this. Each ARRL Handbook cover's it too but their Antenna guide is a must...

Well first I am trying to make a non-axial cap that is about 1/2 an inch too long and 30% larger diameter fit because I have a lot of them on hand. I know first mistake...... So I go to dig out my old Weller Soldering Station from H.S. it sounded like a box full of broken glass.....So she did...

Ok my High Voltage Transformers have no taps for filiamanet or bias etc....they do have two sets of identical HV taps same color wires. I know it is not a problem to wire these taps parallel. Can they also be wired in series with in a single transformer? If yes I would imagine that...

Those pesky 2600's what where they thinking by not giving it an RF power control???? I have known guys that retrofit them with an external pot to control the power and some guys put a high low switch attached to a resistor to drop the power. I would not worry about it too much if it was fine...

I know that when Barjan(sp) bought out Astatic they went willy nilly cheapening everything up so that almost nothing is as good as it used to be before the buy out! Everything I have herd from people my age and older that used Astatic products from the 1940 up until the buy out all say the same...

I am not one to hop around or to go on Mic Safari's!!!LOL I do not buy a new mic unless the one I have breaks. What the heck am I going to do with a ton of mics I can only use one on each radio at a time. On top of that how much junk do you need around the house! I am not one that thinks the guy...

Ok as sopmeone who has owned a President Lincoln since my RCI 2950 was stolen and a person that for the two years I apprenticed at that electronic repair shop prob. aligned at least 100 2510,2600's and my Lincoln and a 3 of my best friends owned these radio's back when I was an RCI2950 owner I...

A lot of counter's are noisey as can be and making them function quietly is quite the trick! Also many of them are driven by the CPU inthe radio and are not accurately displaying the true freq. that is being received and transmitted upon! I call them dummy freq. counter's! They are kind of like...

I thought Bob's was off I80 does I80 run to Penn.?? I bought my SP1-a from him. I ordered it off his sight. Small world. When last I checked the Top Gun Speech Processor was $49 but someone on this sight is saying their $20. That does not sound right at all unless prices have dropped which...

What a thing of beauty! I found an old set of banana jack test leads and quickly put her to the test. Works like a dream!!! She is huge. I would say if you took two standard residential red house bricks and put them side by side it would be the right widths but only about 1/2 as thick as this...

10 and 12 meter are fantastic for long range propagation. If you should ever blow a trans in the TS just make sure you get low beta matched set's. Low beta put out less power but they are much more fogiving. Also I always removed 2290's if one goes bad in an amp and I always replace them all...

As I am leaving my A&P mechanic friends pole barn I spot a partial spool of hot pink wire......Oh wait for it gets good.....So I try playing ignorant and do the hey "What you going to do with that partial spool of hot pink wire????" inthe corner. He looks at me and does the " Nice Try I am...

What are your thoughts on XLPE HV wire? I have a friend that wants to unload some 5000V Single Conductor XLPE wire. I have never used the HV XLPE wire but I have seen the low voltage XLPE wire fail badly due to hydroscopic nature. I have heard that the HV variety is not as failure prone. All I...

This is very true......I can remember the day I became aware of my mortality..........That was the day I first feared for my life when I was climbing with no gear and almost died......I had almost died a thousands time before and never even a second thought no quicken of the pulse nothing...
