    Thinking about putting up a dipole in attic

    Yes, I have other houses all around me all of them have satalite TV or Digital Broadcast TV. Then you have all the computer's in my area. My TV is a Plasma big screen lets hope it does not cause havoc in the HF spectrum!!!LOL So the Balun is being used to isolate my feed line which is coax not...

    I was not trying to make this a committee decision....LOL Just thought I would ask if their was anything I was over looking or needed to know before I dived in head first! LOL n my youth I was known to leap with out first looking now that I am older and sometimes wiser I figured what the heck...

    thinking of making a 102" into a base antenna

    Wanted to add that I have known a lot of people that have trimed 102 inch whips to length for their A-99's they claimed they got less staic during storms and such.

    Thinking about putting up a dipole in attic

    Ok, I am not currently on the air. I am currently renting from relatives and just moved in a few weeks back. The second floor has doors that lead directly to attic space on each side of the finished up stairs rooms! I am on a tight budget so that is why I was thinking dipole. I was going to set...

    Class A bias amp

    The bandwidth you have at your disposal that the radio picks up, modulates and sends out from an audio stand point is very small. Then you have the physical band width allowed on that band that you can use not often ran into or talked about on AM but on SSB it is a limiting factor. Then you have...

    7kW tube

    That would not scare me maybe the power bill would since I have had a heck of time finding enough work the last two years. I would love to have a beast like that if I could afford the power bill to run it!!LOL I would have to install a turbine on the water main, maybe a windmill in the...

    2510 meter question

    I moved recently so mine is packed up but if I come across it by the weekend I will take it out and give it a try. I have not used mine in about 4 years. I have to admit I only use the SWR function and then leave it in RF sensing mode I have never even tried the modulation function. Mine is a...

    The Responsibilities Associated With Using a Big HF Mobile Antenna

    Two ways to go.....Use grade 8 hardware and not chi-com stuff. Grade eight will bend but will not shear under load. I never use anything less then grade 8. The other idea would be to use a copper alloy some form of bronze or brass. They are soft and like wise almost never shear if you make them...

    7kW tube

    Nomad what is the current draw on that beast and is it at 110 or 220????

    7kW tube

    Look at the 6.3V current requirement!!! You are not going to plug a beast like that into the wall of your home. By the time you have the plate transformer going and the fill. transformer going even with no load you would be grossly exceeding what most homes are wired for I would imagine.

    Using Transmitter Tube To Replace Sweeps In Audio Gear?

    You know you do not have to have tubes in your amp for it to sound really nice. You just need a high current amp design that use's discrete components. Carver did some amazing things making transistor amps sound like various high end tube amps by playing around with impedance. He made one amp...

    AM POWER EBAY

    Wow that was a terrible interview......Speaking notes or a Speaking Outline would have helped him out a lot. People think public speaking is easy but it is not. If you want to do it well you have to have a plan and stick to it until you get very good at it!

    AM POWER EBAY

    That is huge and ugly especially for a two pill unit. I had a two pill MRF 455 unit that was the size of a box of allergy medicine. I installed brush less fan motors and a termo switch......Of course my cooling was not patented though and I did not write on my unit with a Sharpie!LOL That has...

    What is the worst source of RFI you have ever encountered?

    Right outside my drive way paralyses to my house are 80KV power lines and step down transformer's for the rest of the area.They are insanely noisy but power company claims they are within limits so tough. It is a signal killer more then a noise issue. All cell phones in my home go from 5+ bar's...

    Inverted V diple question.

    Waverider I used to do that too!!! How funny....The ones I used as long as you had about 500watt's it would cause the car wash to activate. I never told anyone about that I always felt guilty because it was in esscense stealing services! Living in the Coastal Ga. at the time all of us went...

    LINEAR, MOBILE RADIO SUGGESTIONS

    I agree get a mobile radio it will have the power you want and easier to work the controls. Hand Helds are like cell phone they have too many double function keys and the keys and knobs are always too small for any man's hands. Mobiles usually have the power you desire too! I seriously...

    Texas Star DX 1600 X Mobile

    I ran a sweet 16 then latter on a 3200 which internal is two 1600 boards combined. Most people over drive them and let them get too hot sitting in the trunk of the car. I had DX 100 kit on my RCI 2950 and it worked beautiful to drive the 1600

    Check out these spec.'s and tell me if this is reasonable???

    No it is a Kris Power Pump. It is a 1 driving 2 set up. It has a 6JG6A driving 2 6LQ6 tubes. As it stands I have doubled it's amount of filtering already and when done every electrolytic will have double the capacitance it had before since I am replacing ancient paper caps with modern aluminum...

    What the heck where they thinking in 1970's?? A 10MFD 450V Cap???

    I am not poo-poo'ing old tech. If I was I wouldnot be building a tube amp now would I???? Capt. Kilowatt talked me out of doing a mobile tube amp for the time being. So I am not a Tech. snob. As for going to the moon prove it? You can no more prove it then I can disprove it. Kind of odd that...

    What the heck where they thinking in 1970's?? A 10MFD 450V Cap???

    Ok so as if the Cap on the front side of the board was not bad enough I removed the board and found a (2) 10mfd 450V paper Beaver brand paper cap on the back side....... Get this they are 20mm in diameter by exactly 30mm in length and when I measured how much larger they could be then that...
