Hey there all, I have a brewing project that I would like to get going, however I am lacking a manual for my Harris RF-3230. I know for certain one of the supplies has seen an electrical surge of som
Ha! I love it! Finally a use for all those blasted left over xt cases. Just imagine the fun you could have with one of those high end cases with all the extra lights. Gears are turning... Now where i
I have used a product from GC electronics called Tunerlube, part number 10-2610. Probably is enough in the tube to relube every roller inductor in the province/state. It is originally designed for th

Hi to all, I have taken on a project that has been bugging me for a bit. I have a MLA2500 that I picked up that has been retrofitted with a pair of 3cx800 intending to have a transportable amp. From
Before I go too much further, a little framing of my background with tubes. Basically, I have very limited formal training with them directly. Any work has been repairing to bring back to schematic w
I tried a couple of programs to see if the values in the existing circuit were even in the right area. PiEl seemed to be the easiest to play with the values to get a result that seemed to match what
The amp came already modified with the 3cx800s. It was done up by W4EMF. One of my EBay finds that has found my bench. Yes that is the technique that I was using. I was using a miniVNA box, but that
Pretty sure I have it. I pulled as much info on the various conversions to see what the history of the changes were. Mainly was looking for any significant differences to see if maybe there was a pre
A little trick I use at work with that brand of label maker is to curve the label along its width, concave toward the sticker, It causes the split down the length of the label paper to pop open and s
Hi to all, I am attempting to help out a friend with a Yaesu Quadra VL-1000 amp that appears to be giving a weird problem after a recent radio upgrade. When transmitting through the amp there appears
That is what I was thinking initially, but it seems to be there with the amp in full bypass. Also it seems to disappear if the amp is removed from the circuit with a barrel connector. Supply is separ
A little further progress, I had a chance last night to check the 48v supplies with the scope and all seem to be good for regulation with no sign of rf on the power. Line regulation is about 3 to 4 v
As I understood it, they are looking for co-ordinated beaconing with the effect of creating a larger signal than would be possible with one station, so that the wide band receiver would be able to se
OOps! Lets try that again so that all may reference. Here is the status so far. I placed in link for future update reference. Hope this helps out. Chris VE3CEA http://www.pwdahl.com/PWDnews.html Late
a business card and contact cleaner without oil will work for most dirt too. use a dry card for final polish. if very pitted a point file will get you a smooth surface again, however if the surface i
Hey there, Ok, before we go exploring the circuitry a necessary statement, this amplifier contains voltages that will kill you dead if you put yourself in contact with them. If you do not have the ex
Oops, Buggered up the reply, I try again... It is actually 2 circuit not two phase. They are running a pair of toroidal transformers to get the capacity and feeding each one off a separate 220 circui
