    ICOM PW1 Amplifier

    If you are aware of it, why do you keep talking about key up timing? Is there an unkey delay or something they added in a software update?

    A couple of questions on Transistor amplifiers

    I have driven by our local radioshack every day for 4 months and the thought never crossed my mind to stop. A few years ago half of their component bins were empty and the owner said everything had been on order for months. He didn't seem confident that he could ever fill them. I'll have to...

    Base A99 Height question

    Did you honestly believe he meant 0.666:1? I know that you know that isn't possible, nor is there a meter available that would read as a ratio to 3. Was it written as a ratio? nope. You are likely just being stubborn and nitpicky. That is ok, just don't be surprised if someone calls you on...

    Base A99 Height question

    If we wanted to get technical, swr claims on this forum are typically just readings from an uncalibrated and relatively cheap vswr meter and will differ from the actual swr. It would be silly for me to say you should state "my uncalibrated vswr meter reading is 1.5:1" I may however start...

    102" whip vs the rest

    I'd guess it wouldn't help much, but I am no mag mount expert. It's been over a decade since I've used one.

    102" whip vs the rest

    Is this a mag mount specific competition? If not, you will likely lose to anyone not using a mag mount. Your ground losses must be massive for a whip that long.

    I would hope you wrote it out in its entirety on a formal maintenance log. There is always a chance you could have to defend your log entries in court. If you record the ":1" in your notebook while tuning your personal yagi, you are ocd. There is no problem with that, people just like to...

    Mobile installs aren't fun

    I don't know of anything that will be hurt by choking, and choking can significantly reduce many problems in a mobile. I can tell you that my 955hp would blink the seatbelt light and a few others barefoot, and now at 10 times the output I have only seen the seatbelt light flicker a few times...

    Do you work in an industry (or know of an industry or situation) that expresses swr as a ratio like "3:2" or something? In CB and ham radio it is always expressed as "x.x:1" so the experienced operators here know right away that it is in fact a ratio. Seriously though, is the "1" in the ratio...

    TX Star 250 dx SWR ? (Something lost it's value ?)

    I'm just giving you a hard time, but now I am curious... If my swr meter reads 1.1 on 20 meters, and 1.4 on 40 meters... is my singular swr 1.25?

    Mobile installs aren't fun

    Palomar Engineers offers some choke options similar to what I made. There are a few frequency/impedance graphs if you are interested in learning more about different choking methods.

    TX Star 250 dx SWR ? (Something lost it's value ?)

    I have a pretty long end fed, and it has many different swr's depending on the frequency. I can see how it could be annoying though.

    Mobile installs aren't fun

    I did consider 4-6 turns on 2 large toroids, but all of that wouldn't fit under my headliner. Instead, i did the best I could with the info I could find and substituted lmr400 for the rg213 on the G3TXQ chart. I plan to minimize ground losses as much as possible, and hope to reduce the cmc to...

    Mobile installs aren't fun

    You don't believe the 10 mix 31 beads I have installed are enough, and think the amp is probably clean? I'll have to research the effects of added power with cmc. I don't recall it causing higher swr, but it's been a long time since I haven't wrapped small coax through a few torroids. I...

    I'm not really certain what you are trying to say. At least the the warning served its intended purpose.

    Can you imagine how many returns they'd get if they set it at 1.5? A 3.0 isn't going to hurt anything.

    Mobile installs aren't fun

    Edit; I can't believe I asked a question this stupid. I guess I have been using ham gear so long I completely forgot everything I learned about CB. I only have my hood bonded right now, and my swr always goes up .2 at full output. 100 watts radio only 1.1, radio only driving a few watts with...

    I said "antenna system" but this isn't really the place to argue about it. I'll leave you to it.

    So the SWR dip of a properly designed antenna system indicates resonance. Oh wait, you just had an urge to be negative. Carry on...

    South Dakota Storms

    I work a quarter mile from that truck stop, and that whole town got destroyed. There were six storm chasers setup with big dishes across the street... that is a sure sign to go home early!
