I have been coding some cool analog meters for SDRSharp, a SDR program.
The latest features my R4C, some on the list may have an interest.

Jim, I can do a TR-7 meter but need a very high resolution, well lit photograph 
taken directly in front of the meter.   I have C and B line but no TR7...

[Drakelist] Hayseed Caps

2011-03-27 Thread Don Rasmussen
Hello All,
 
I have a pair of R4C's and an R4B that will get new electrolytics. They are 
stock at present. First job is removing the old cans. All I have is a Weller 
gun at present100/140 for the removal. I have a standard iron for installation. 
If anyone can suggest the best way to remove this solder from the chassis and 
twist tab - a specific tool or method, the rest of the job should be managable 
at first glance. 
 
Thanks in advance,
Don

[Drakelist] Simple R4B troubleshoot

2011-03-17 Thread Don Rasmussen
Hey guys,
 
The fuse blew out on my R4B today. There are 2 filter caps that I am inclined 
to check, one is mounted underneath the power transformer, the other is the 
larger silver can mounted above the chassis. Can these be tested with a simple 
VOM? What readings to look for - shorted? Also wondering what else to 
test before tossing another fuse in line. 
 
The wiring attached to the NOTCH pot also seems to be disintegrating all by 
itself - interesting. 
 
Thanks,
Don Rasmussen

[Drakelist] Deoxit debroke it.

2010-03-02 Thread Don Rasmussen
I sold a Drake C Line to a ham friend a few years back. It had been fully 
functional for me for months and the fellow came over to pick them up. I fired 
them both up in front of him, on my antenna and went everywhere, all bands, 
everything worked - HAD FUN!

He carried them out to his truck (smiling), they went on the passenger seats 
with towels over them. I get a phone call an hour after he left (here), him 
wondering why this receiver is DED. Nothing - flat out unresponsive. My jaw hit 
the floor. 

Something happened in the cool down period at my place, during the truck ride, 
or upon setup on his side. He's an honest and smart ham.  I learned never to 
assume any cause nor affect with things so mechanical in nature. 

My guess - the deoxit may seem like a red flag but it could be s many other 
things...

I have used de-oxit many times on old National, and Clegg equipment, 
both on switches and on pots.  So far, I have had no trouble from it.  I 
may even have saturated the wafers on a switch or two in the process to 
no ill effects.  I am much more careful with it now, though.  Many of 
these components are almost if not impossible to find now, and I don't 
want to take any unnecessary chances in wrecking something.

Actually, I had PowerSDR running here using LP-PAN. I cannot argue with the 
transmit fidelity which is noticably the best on the band. But on receive, all 
of the DSP receivers that I have listened to sound distinctly digital (which to 
my ears is not natural having grown up with DRAKE), and so, not fitting to 
emulation. Elecraft somehow got the AGC right and you can hook up a big honkin 
speaker to it and fill a room with the audio. Close your eyes and it's... 
Drake. 

Anyone have a DSP rig that sounds analog like K3


Don -

Very nice!!

Now all you have to do is make a skin for the PSDR or GSDR Software 
Defined Receivers..

Hey Guys,

I've made an R4C skin for the PC and Elecraft K3. 

Take a look here:

http://www.zerobeat.net/mediawiki/index.php/K3_DRAKE_R4C_Emulation

http://www.zerobeat.net/mediawiki/index.php/K3_BSR-SM_Version_7

You can see in the first image I added NR, PREAMP, and ATTN indicators on the 
CW positions, and the DSP bandwidth went in the Auxillary Crystal selector but 
for the most part the rest of it is stock. The K3 does a better job than most 
at emulating the FB R4C. 


Cheers,
Don

[Drakelist] How to clean Drake knobs?

2010-02-28 Thread Don Rasmussen
A Bounty towel will polish the Black to a high shine, then take a Bounty sheet, 
fold it into quarters and lay on a flat solid table. Take some cheap white 
model paint (I used Testers) and lay the paint in the groove at the top of the 
knob and then in the groove at the front with a model style paintbrush (cheap). 
Slop outside of the grooves slightly and load the paint well in the groove. Let 
it dry for a minute then wipe each side of the knob on that paper towel. That 
will take the slop from outside of the groove and polish the knob. That's how I 
did these: http://www.zerobeat.net/wb8yqj/DR4C.jpg

It goes fast and easy...

I always used the lacquer sticks..available from engravers supply 
pl;aces.  The only problem with them is the knob lines are very wide and 
deep--relative to normal engraved lettereing--so it is easy to get a 
kind of gobby application if you aren't careful.  Lately, since starting 
to use them in modelling, I love the white paint pens..from artist 
supply houses.  If you try a couple of different tip sizes, you will get 
one that lays right into the knob slot with no fuss and no muss.  My 
opinion is these are now the way to go.

And if you feel wild, they are available in a rainbow of colors :)

Curt
