    Sufficent drive for amp

    Ok this is more information that I can deal with. I guess to run the amp the way I was intending it would need to be putting out 200 to 300 pep watts at - 35db. which is the legal limit for the ham 1500 watt amps. This would be 50 to 70 pep for each device. This would require around 2 pep watts...

    Sufficent drive for amp

    It was just reminded, a negative feedback circuit was installed. Still wondering about my questions though.

    Sufficent drive for amp

    Ya I understand this and have run it like that since I accrued it maybe 7 years ago. I was thinking that even at this level I overstimulated the devices. So your calling these 2879 devices 150 watt level? Why not 400 watt box? Maybe because of the frequency they are used in as compared...

    Sufficent drive for amp

    Supposed to be AB, according to Justin DePolis. Like I said I am a little bored and want a clean signal. The power output I understand will have little bearing at the other end. Sometimes a little knowledge is a dangerous thing! I understand that many myths prevail. Just want to do the...

    Sufficent drive for amp

    4 2sc2879 transistors, converted Twister am, was a 1x4 now straight 4 pill with bias. From the spec sheet I see the 4 pills need around 20 watts drive peak to saturate. Using a Stryker 440hp running at around 3 watts dk seeing around 20 peak with mic cut back to get this peak number...

    Wilson Gum Drop Studs

    Yup been there and done that, gumdrop mounts fail. I have had great success with predator 10K mounts, ring terminal of course.

    Bird and slugs

    I understand. My reflect is pretty minimal so I guess it's really is not an issue. The MFJ 259B helps me with this too, so I suppose that is enough. I see around a 1/6 to 1/8 of watt at 100 to 150 DK. Even using other SWR meters the needle usually barley moves. So 1000 watt element it is for...

    Bird and slugs

    What would be a good combo for a Export radio with a 4 pill amp (2879)? I would want a slug for reflect too. Last test the amp did 620 43P watts with a clean radio driver. I would like to be able to measure just the radio a Stryker 440hp as well as the amps output. Money is a factor so I need...

    variance in swr readings

    Well that move changed things so you will have to re check it. I was dealing with 1/16 of an in. to get the R50 X0 numbers with both location and stinger length. Another interesting thing is that it would change with regards to the Suns elevation and even direction of the car regarding the...

    Is this the new Stryker SSB?

    I will be waiting for this to come out before deciding on AM/SSB purchase. I love my 440hp.

    Predator10kdiscountantennas

    Went through Mike's Electronics. I had a very pleasant conversation with Mike and he answered all my questions fully. I had questions and I wanted to talk with someone. "predator10kdiscountantennas" was not available for that.

    variance in swr readings

    Not only adjusting antenna whip length but location can change the readings. I once got a R=50 X=0 but it took many hours of fooling around with the mag mount and 10K. Going to the 22 in. bottom shaft is what finally did it in my case. In the big rig I ran the 17 in. bottom with dual coil and...

    Is this web site still operational and is it trustworthy? I am looking for some terminal end coax and they have it apparently.

    If you are interested in Optima batteries.....

    I have a Optima Red which I installed in my ( 4 runner over 100,000 miles ago and 9 years. I've run my 4 pill off it as well as the car for almost all those years.. Still working.

    New Magnum series replacement for "S"

    Now I am thinking I should wait to see what the new series will be. I have played this game before with the first Stryker 440hp radio. Hell for that matter I am still waiting for their SSB radio, ha ha. I think I need and AM first with a good quality SSB function. I like the package with the...

    How bad is it in your area?

    Having started in CB during the middle 70's I can say that it has declined significantly. When Silicon Valley infrastructure was being developed everybody was on the air in the Big Rigs that supplied all the materials for the building of the Valley. While running "over the hill" to pickup...
