Got a RF Limited CR577, which has been working great for me. Recently, it started acting strange. When I key the mic and apply a constant tone, the watt meter slowly rises to full output. Using the stock mic on the radio, the watts quickly jump to full output as expected. Once the output...

No worries Eric, I understand the frustration (I work part-time at a RadioShack... some people shouldn't be allowed near technology). :headbang I am a very inquisitive person, and try to read and understand as much as I can, and seek outside help only when I've done everything reasonably...

Thanks hotrod, that sounds like what I pictured would be the way to do it without equipment. :) Its something I'd really love to do eventually, but right now its what the budget allows for. Certainly a bit better than my DX979 on initial sideband stability though! :laugh:

Gotcha, I'll take a look at that when I get a chance! :thumbup1: I suppose I would need more equipment than a Frequency Counter to accurately set that hm? (Its what I have on hand). Aloha, Trevor

So as I understand it, this only becomes a problem if there are very strong signals on adjacent frequencies.

I thought they weren't to be resold?

Gotcha. So its not necessarily my radio's transmit, but the the receiving radio's design. That makes sense, because if a receiver isn't passing the whole signal, its essentially clipping the audio off, hence the distortion. I'll have to check out the board on my radio when I have time. The...

Sure, I read that, no need to get aggressive. Hell I started this thread, I have every motivation to read the posts. But what does that mean to me? I know what white noise is, but how exactly does image rejection affect me? Sorry that I'm not an RF engineer. I tried to do some reading about...

Mad Scientist: So what is this modification intended to resolve? It must do something, no?

I hope so too... :unsure:

Thanks Shockwave. Actually my radio picks up FM well, my buddy on a 2970 comes in on FM just as loud as AM. The concern is my FM transmit, which actually now that I think of it, actually tends to overmodulate unless I back the mic gain down, at which point it becomes quiet. Is there some kind...

Update: I received the radio I ordered and have been using it with good result, but I recently discovered the IF mod has not been done, upon looking at the warranty sticker (intact). Dave did offer a refund, but I want the mod done, so I'm sending it back. This offers a chance for me to make a...

So it looks like Dave forgot to do the IF Filter modification I ordered. He send a refund, but I'd like to have the mod done since I use the radio primarily on SSB. Plan on sending him the 2950 as well as a 949 to have aligned. I suppose this offers the ideal opportunity for me to update the...

Dave suggested using the variable knob on the 350 to back down the power, but I've already tried that (and fried it, as expected). Any other suggestions? The radio does seem to get very hot when the variable is wide open, so perhaps it has been tuned a little too hot.

I use these products for RC, just a few comments. The lithium batteries are pretty safe as long as you follow a few guidelines. Don't exceed their recommended charge/discharge rate (indicated in units of "C", where C is the capacity, ie 4200mAh, 4.2 = 1C). Do not discharge them below their...

I have a Bazooka Dipole that is essentially strung up on the side of my house right now. You could easily hang it under the eave of a roof, or in an attic. Its horizontal on the side of the house facing Australia, but a few days ago the band opened up and I hit Europe, with multiple signal...

Hey there 9C1Driver, thanks for the advice. I purchased the radio from DTB, he did whatever he does to it before shipping it out. I ordered the IF filter mod done too, but the RCI warranty sticker covering a top cover screw is still intact, so not too sure about that one... Maybe I'll give...

Got a 2950DX driving a Texas Star 350HDV. With the variable power all the way down (box off), I'm still getting about 30W swing on sideband. AM gets me 2.5W swinging 8-9W, no problem there, although 1.5-2W would probably be a little better. I want to turn down the low-power on the 2950DX a...

Any one try Nichicon electrolytics? Planning on recapping a 2510 with some.

FCC?
