    Made my own power microphone

    Yep, all the reports said the modulation was low, considering the carrier, and as stated, I had the external mic gain up all the way on the radio. I don't think the problem was the mic because the mic element is just a simple "speaker in reverse"... if the voice coil is good, and the cone isn't...

    Made my own power microphone

    It seems the consensus is the stock mic works well. That leaves me with two "scenarios". My mic was defective, my radio is defective, but works well with more input audio. I got reports from a number of stations and they all said modulation was low with the old mic. I must have an older...

    Made my own power microphone

    Hmmm. Thanks for the input on the stock mike fellas! I do appreciate the feedback. I'm not sure what to think about my particular radio now. Who knows... factory defect?? Regardless, for my radio, the Cobra/RCI mike is doing the job for me. So far I haven't seen any display problems. Of...

    Made my own power microphone

    No sound bites yet, sorry. I'm not sure about "continuous voltage"? I think you mean that you have to bring in a power wire for a new electret, and the old element is not electret and needs no power? Btw, I found out that my electret got "squirrely" if I had too much voltage on it. Five...

    Made my own power microphone

    I have an RCI-2950DX. When the radio first arrived, I couldn't wait to get a few signal reports after putting up an antenna and hooking up the radio. Unfortunately, I found out pretty quickly that the stock microphone really does a poor job in modulating the radio. It was kinda disappointing...

    RCI 2980 WX transmit POP noise.

    I have the "pop" in the speaker on a stock rci 2950dx when I key or unkey the mic also. Sure is annoying. I can't remember if it did that from "day one", or if the pop came later and I just didn't notice it right away.

    Gotta get me a crank-up. Too old to climb anymore. :-)

    Dipole on the living room carpet?

    Reconsidering, first get something up easy and quick, like a vertical dipole or the quad loop. When you're already up and running, you'll have plenty of time to study antennas like the mag loop, and you could learn and construct it at your leisure. Like vkrules said, get creative and start...

    Dipole on the living room carpet?

    Oh yea! And it works just the same in reverse, which means all the digital noise from the neighbors (and your own) will haunt your receiver also. I've been there... antennas in a "confined space because of my location". All you can do, is do your best to find the best location in a bad...

    Using the rci-2950dx on cw question

    Uhh oohh. The plot thickens. I had an "accident" with the radio awhile back. I had the radio open and was checking some voltages with a meter. The meter probes slipped, and when I put it back together, I found the radio would not key up in transmit again. Oh crap. I had to troubleshoot and...

    Using the rci-2950dx on cw question

    Good advice to try another speaker. I haven't, but since the thumping is still there when no external speaker is used (using the internal speaker) I figure it's not a speaker issue. I may try inserting, in series, a capacitor (say 2uf) with the external speaker. That would block any dc...

    Using the rci-2950dx on cw question

    Hmmm. I get a distinct "thump" in the spkr. with every keydown, besides the sidetone. Guess I'll have to bring out the test equipment. I'm thinking that maybe DC is passing through the speaker along with the audio tone. Just my first guess. Thanks for passing along your observation with...

    Hope you get some relief, I never did at my last two locations in Indiana. Good luck Al.

    I hope, over time, you get the feeling back in your finger m42duster. Sounds like you have "compensated" pretty well for cw in spite of the injury. I use a pretty light touch on the buttons myself. Thanks for the "thumbs up" Bruce!

    Doc, Yes, you start pickup up familar patterns of sounds. You get where you recognize common things like CQ, 5nn, hi, etc. I guess most of us had someone that suggested their favorite learning method. It also depends on when you got started. When I was starting out, the method to use was...

    Thanks mkube396! You mentioned not having rythym for it. I'll just guess and say you mean you have trouble trying to receive it, and not sending it with a key. I learned the code by listening to it sent slowly on a recording. The recording sent the letters in random, so you couldn't...

    RCI-2950DX transistors or mosfets?

    Hotrod is right. it swings to about 25 watts on a "whistle". Update: After digging into the posts in the CB modification section of this board, I seem to have found some info on this subject of the mosfets. The majority opionion is that the 'fets are no better, and possibly worse than the...
