    gamma on a mobile ?

    I think we're debating theoretical vs practical on a bunch of different levels... That's a no win. I'll say this in closing and then you can have the last theoretical word. If the OP taps an existing puck like fatboys (I may be wrongly assuming he doesn't want to go to the trouble of...

    gamma on a mobile ?

    because the coil thingy is too big/tall when designed to accomodate high power. the coil will terminate several inches higher than the feed point. This is where the theoretical hits the practical road. For everyone who's following along - myself included, it might be easier if you included an...

    Amp coax jumper length

    ... never mind. not gonna argue with booty over this. I've watched him for years parrot what somebody else told him. this one is probably better left alone.

    gamma on a mobile ?

    I think the puck is too short for the coil.

    gamma on a mobile ?

    Not really... the height of the puck won't allow for a proper high power coil's overall size if it's going to be fed at the bottom of the vertical. The coil ends up being fed into the shaft several inches above the feed point. I would also think the coils proximity to the body metal would...

    Amp coax jumper length

    If the amp is presenting a 50 ohm load at the input you can run any length of coax and it will present 50 ohms to the radio. If it's not you're better off cutting the coax at 1/2 wave-length. Or, if it's not and you have the means to model the transmission line you can cut it specifically to...

    I'm done with Nittany-Scientific... Zero customer service. Would never reccomend them - ever.

    Nittany-Scientific

    This might be mis-catagorized - it's more of a company question. Has any one ever dealt with Nittany-Scientific? I've been trying for over a week to buy the NEC-Win Synth product and am getting no-where. I can't believe in this day and age it's this tough to get a peice of software... Monday...

    Freaky Flashed Face Distortion Effect

    I think the take-away is... if we could get women to actually look at us and not passed us - we'd have a better shot.

    My First Attempt At A Mobile Antenna

    A wide banded coil also has a lower Q... If he's going to use it on a single band there is no point in optimizing the 2:1 characteristic... it may make sense to make it as efficient as possible for the intended frequency.

    DAVE MADE M400 MOBILE LINEAR AMPLIFIER 1-2290 X 4-2879 BY DAVEMADE

    I do feel better! You're right, the use of "fine" was a poor choice of words and the post was poorly written and unclear. don't want to beat the horse as it's not going to add to the thread, except in length. :oops:

    DAVE MADE M400 MOBILE LINEAR AMPLIFIER 1-2290 X 4-2879 BY DAVEMADE

    I feel thoroughly schooled... feeling better now that you've gotten that off your chest? You made my point even if I worded it poorly... Shockwave said the design could lead to self-oscillation, I'm sure this is why you see most of the comp rigs running external drivers and not the...

    DAVE MADE M400 MOBILE LINEAR AMPLIFIER 1-2290 X 4-2879 BY DAVEMADE

    would you know if your amp was self-oscillating. Not asking to be a smart ass, I'm just saying a lot of people wouldn't be able to identify it or diagnose it... Your box can s/o and still transmit just fine... my 2x12 does.

    Texas Star Amp Repair free help

    Wish I had known about you a couple of years ago... I've managed to blow up a 350, a 667 and a Sweet 16... sold them for parts :( LOL... Took me a while to figure out the drive limitations of the that bias. Will definitely read your site over with some interest.

    Got my Mauldulator today, WOW

    Yeah no worries. Before you're done with his product you're going to run Motormouthmauls good name into the ground. He would have been better off producing the product and selling it himself; at least he understands radio and could have intelligently defended the project.

    Got my Mauldulator today, WOW

    So, forgive my ignorance. If the mauldulator dead keys 1 and swings cleanly to 8 watts (200%) how is that better than my radio that dk's 2 and swings to 8 (100%)? I'll still be driving the amps the same and whatever "loudness" is gained by the high "modulation" will probably be lost in real...

    Speech processors: do you use one?

    Couple of questions for those in the know: 1.) Does RF Clipping like ten-tecs work on an AM only rigs; seems all the references are to SSB... 2.) How well does signal processing work on high modulation designs like CB, versus the low level mod of ham?
