    Anyone build an amp with NTE317 transistors?

    That is why I bought one designed by Brian Griefy(sp) and then proceded to purchase circuit boards from him to build my own. The only way it could have gotten any better would be if JRC sold kits! LOL In a perfect world it would have been RF Fet based, band tuning, legal limit, and swr pwr...

    Anyone build an amp with NTE317 transistors?

    I agree parts are parts if they work as intended or the crcuit can be uned to make non-origanal parts work! Up until recently I could get a great deal on MACOM MRF454's at a good price point so I used them to replace the insanely priced Toshiba 2SC2879's in my gear. I have HG2879's but have...

    Thinking about building a small ground plane for temp. use at other locations.

    So I am on the right track. I figured I was not too far off but that was assumption on my part. I use a tuner in my house but it is the size of a boot box not what I want to lug around. I figured same parts of fixed value would need to be in the circuit but nice to know it is not impossible to...

    Thinking about building a small ground plane for temp. use at other locations.

    I considered doing dipole out of dual whips. Why? Because It is not wire I have to hang, slope, invert, etc..... I do have two large Saturn Aura rims with light lip damage. I could mount a plate to that and slip a pole in and bolt antenna to. It would be heavy and take up some trunk space but...

    Anyone build an amp with NTE317 transistors?

    I recently fell into a great deal. I got 8 of them at $24 each NOS still in the plastic retail bags like you would get at electronics store back in the 1980's. Imagine you walked into your local TV repair shop/radio repair shop! You can not get MRF455's for less than $79 each. I figured I can...

    Telstar dx250 and dx 350 amplifiers

    I like to put it like this! If you sell me a 400HP car I intend to use all 400HP regularly. I expect the engine and the transmission to last me at least 300,000 miles with proper maintence. If you it can not do that you are a loser, liar and fleeced my wallet! I believe in continious power...

    Telstar dx250 and dx 350 amplifiers

    I own about 12+ of his PCB's and have built 3 seperate designs of his. They are fantastic. I have owned one of his finished units and it is fantastic. Everything he promised and no hiden issues. I would love to own a Tokyo High Power, Henry or JRC but they are out budget and I amnot even sure...

    What electronics have YOU fixed lately?

    In Boy Scouts the new kid if smart and independent got all kinds of craptastic work to just dog on him. Imagine having to un knot crates and duffle bags of knotted ropes probably decades worth. To this day I can unknott and untangle things like those Rubix's Cube competitors. I can talk and...

    What electronics have YOU fixed lately?

    I recapped a 2003 Toyota Camry ECU. The patient made a full recovery! Sadly rust will get her long before anything mechanical does!

    Thinking about building a small ground plane for temp. use at other locations.

    So when I go up to my mother inlaws place a convient ground plane I can just chuck ont he ground for 10-11 meter use. It will be built from stuff on hand. So probably 108" whip, some Francis 2 or 3 foot fiberglass wound antenna's as radials, some angle brackets, maybe some aluminium on a...

    How Bulletproof is the 13N10 Power MOSFET ??

    If heat is being generated in the drivers and finals than it is trying to transmit and the heat is evidence of that! Never seen an export wanabe amateur radio from China or a CB with SWR PWR fold back!!! This is not made by Tokyo Hypower or JRC in Japan! LOL Heat especially extreme in the...

    Inspect Your New Amps

    Imagine a car forum and someone is warning people about an engine problem but then refuses to tell people the Year, Make, Model, and Engine type! It would be a worthless post of no use to anyone! At the very least put a zip tie on that wire until you can get a proper strain relief. That...

    High quality knock of Toshiba 2sc2879?

    A lot of people are very hapyy with the HG2879 16D08. They are not perfect, and not as durable, and do not make the power but the price is good. You just have to operate them like a sane person not your average idiot! If you try to push the voltage or drive like some would on the Toshiba they...

    Adding swing

    Have you considered turning the low carrier downt o 1 or 2 watts and letting it swing adjusting the modulation and maybe slowing down how aggressive the AMC is? Then put a decent amp behind it. Maybe add an EQ inline and doing a gold finger audio mod to it? I am not against direct injection...

    This guy must be smokin' some stuff....

    They are worth what ever you can get someone to pay for them that is "fair market price" by definition. If he is willing to sit on them long enough and pay listing fews he will eventualy get a lot more for them than he really should. That said there is that guy from Canada on Ebay something...

    Presenting the reincarnation of the sl41 (stryker sr-76nc)

    I do not think it matters if it is a physical clone only a performance clone. I like Dino Ferrari's but I am after the experince not a part for part clone. Same thing goes for a lot of other things from food, to rifles to experinces! If it is sonicly good and durable I do not care about much...

    So My Radioddity QT40 came with a programing cable.

    Not sure if this is the new normal but mine came with this. I have not had more time since it arrived 2 days ago to see if it comes with a software disk or anything else. In the past I thought you had to pay extra for this?
