    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    I have read everyone's comment and will reply as soon as I get more than 5 minutes of time to myself. For the time being, my little 7 month old daughter is requiring me to give her 135% of my attention. Thank you everyone for all the comments and help. Will be back soon!!!

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    Many thanks. That is the only thing I have not yet tried. Yes.... yes.... I know. Pretty dumb of me to come on here and bitch and moan about how I can't seem to get it working yet, I have failed to follow the all the directions. Just FYI.... I stopped by the Electronics shop on my way hime...

    WHAT TYPE OF AMP IS THIS?

    So I received the amp. Nope!!!!! Looks nothing like that nor does it look like any other amp I've seen before. I will tske a photo and post when I get a chance. It actually does have a pair of 1446 in it. However, the PCB board is one of the regular commercial type mass produced PCB...

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    Please elaborate. How and why am I doing everything wrong captain? In regards to my negative power line, please re-read my post. It is not coming from the battery. It is coming from the metal body of the car. However, even if it was coming directly from the battery terminal, why is that...

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    Please excuse my stupidity, but what is MO? And to answer your question: No. I just started to post on forums about a month or so ago. Who is this guy DualAntennas? Must be one heck of a smart guy. ;-) No, I appreciate the help and I hope you did not take any offense to what I said...

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    Yeah. Not a bad idea. I need to try that while going about 60 to 70 miles per hour down the highway. LOL. But I would be almost positive to say that when I let go of the accelerator, the voltage should drop from lets say 14.xxV to 12.xxV or 13.xxV because the alternator is not turning as fast...

    Radio Shack SWR Meter & Testing Analog Panel Meter

    Thank you for the reply and the comment. I appreciate it. However, I highly doubt it. Because as I mentioned, I used a 100uA and it was too small. And a 1A is so large that the needle does not even move. I think it's somewhere around 200uA to 500uA. Or maybe even 150uA..... Unless I do use...

    Radio Shack SWR Meter & Testing Analog Panel Meter

    Gentlemen, I have 2 questions: 1. Does anybody know how to test unknown panel meter to determine what the rating or capacity of the meter is? To see whether it's a 200uA, 100uA, 1A, etc.... I remember back a while ago, I found a diagram on the Internet which was basically wiring up a...

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    Just A Friendly Bump I've noticed when I am in the car, I'm going down the interstate, my dead key seems to drop lower when I press on the gas pedal, and when I take my leg off of the gas pedal, the deadkey goes a little bit higher. Depending on the radio, I've had up to 1.5 watts fluctuation...

    WHAT TYPE OF AMP IS THIS?

    Yeah.... I know. That is what I was going to do anyway. I would be dumb not to. I get all excited when I am getting new amp for some reason even though I have 4 of them, (w/ exception of my MS500) and they're all the same thing (all a pair of 1446). Right now I am using the Galaxy 225, thanks...

    WHAT TYPE OF AMP IS THIS?

    Good Sunday Morning. I am being sent a "Little Red Hooker 250" amp. Attached is a photo. Does anyone know anything about these? What type of transistors it has and how many? I currently have a Galaxy 225 with 2x SD1446 and this looks to be the same as any other 2x 1446 transistor amp, but...

    Tuning / Modifying a TPL UHF Amplifier

    Shockwave, you know, as I read what you wrote, I kind of started to think that, but I started to tell myself I was probably wrong and should ask. Funny thing is that I tried to adjust them before and I still got nothing, but when I think about it now, I was not taking my time and doinh minor...

    Tuning / Modifying a TPL UHF Amplifier

    I am about 80% uncertain what you mean exactly in regards to how that would relate to the operational frequency range. So could you please explain a little?

    Tuning / Modifying a TPL UHF Amplifier

    Sorry. I missed this post earlier. That is true and a great idea too. I will try it once I'm back from the trip. However, the service manual says that those 4 capacitors are specifically for input and output impedance matching. Please see attached. With that in mind however, I am willing...

    Tuning / Modifying a TPL UHF Amplifier

    Components Values May Help????????????????????? Hi. Thanks for the reply and confirmation. Yes, that's what I figured. However, my problem is that I am not sure which caps are in there for the frequency bandwidth and which are there for the bias. I have looked online everywhere for some...

    Tuning / Modifying a TPL UHF Amplifier

    Hello Guys (& Ladies), Some help with this issue will be mucho appreciated. I got a good offer to buy a variation of the TPL UHF amplifier PA6-1AC. The unit label says 400-512MHz with a sticker on the other side saying pretuned for 403MHz to 423MHz. Below is the basic specification for the...

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    Thank you again for the info. Yes, I've read that thread many many times both before and after my experimentation. It is very helpful. Well.... I can't currently use the 2300 meter because it is packaged up to be sent to Comet for repair. Since I got it from day one, regardless of how...

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    I'm not talking about the max to push the final super hard. What I meant I guess is the max it will handle or be able to put out without any obvious stress being placed on it or pushing it extremely hard and without any sort of audio distortion. Basically with it sounding good and not being...
