[drakelist] OT: Difference in Vibroplex bugs

[EMAIL PROTECTED] made an utterance to the drakelist gang

hi,

I sent this to my CW mailing list but there's a much larger audience here
so i'm sending it here as well...


Just wondering if anyone could help me figure out the difference in some
of the various Vibroplex bugs.

I've found about 4 different variations:

Lightning bug
Original bug
Blue Racer bug

And then for the Lightning bug i've noticed some have a square looking
damper for the arm, others just have a post for the arm to rest against.


If I were going to find one of these to buy and USE are there any concerns
using the really old bugs vs. using the new bugs?  I've got a deluxe
original made in 1986 that is quite nice but I thought i'd have a little
fun with some of the really old ones...  but I don't know if the old ones
are more trouble than they are worth.

Thanks for any advice and recommendations.

As far as I've seen, age makes no difference in operation, it's mainly

Jason,

One difference in bugs that should be noted: a blue racer is about 2/3
the size of a standard bug, and it tends to be a bit faster at its
slowest speed than a standard bug, hence the name. Vibroplex sells a
product called a bug tamer which is essentially an extension to the
arm, permitting the weight to be mounted farther out on the arm, slowing
the speed. Slow speed on a blue racer is around 22 WPM, I think.

Al's comments were right on - it's really about adjustment, not age.

Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang

Keith -

Good point.  Couple of points. 

1.  In over 40 years of owning, using and working on  _lots_  of Drake 
gear, I have never seen a failed AC-3/4 transformer.  I'm sure there 
have been some, there were probably some with manufacturing defects.   
They do thump if you happen to close the switch on or near the peak of 
the AC waveform, but it doesn't seem to hurt anything.


2.  What usually kills power switches is the arc that forms when the 
switch is turned off from the inductive kick of the transformer 
winding.  Second is the growth of a small bump on either of the 
contacts that makes first when closed, which forces all the current 
through that bump before the rest of the contacts touch.  Good 
contacts, closed, are pretty tough!


The Sigtomics units look nice, and not ridiculously priced.   The 
thermistor components are readily available, and can be installed 
directly in vintage receivers for a lot less money.  They aren't as 
useful in transmitters because of the large difference in turn-on and 
full power transmit power requirements.  You pretty well have to have a 
relay to short out whatever resistance you put in-line at turn on.  The 
first thing I did to my L-4B when I got it 30 years ago was to put a 
time delay relay and power resistor.  The amp still has the original 
tubes and original pilot lamps.


Anyway, there is certainly nothing wrong with using the Sigtomics units, 
but I'm not sure they will really improve the reliability of the 
equipment significantly over an external power control.

Generally speaking, the older bugs work just fine, if they're complete and
not bashed up.  I've found some issues with badly burned up contacts on some
of them.

My personal favorites are the Lightning Bugs and I have several of different
vintages.  They all handle about the same, although I'm stuck on a WW-II

Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang

Jason -

Personally, I think the older bugs are much more responsive than the 
ones made later.  I have heard that Mitch has improved the quality over 
what it was a few years ago, but don't have any personal experience.


I have four or five, mostly from the 60's and earlier, and one or two 
from the down years.  Something that seems to me to be somewhat 
consistent is that the older ones have a more lively spring, that will 
produce a considerably longer string of good dots than the later ones.


The Original model is what I consider the workhorse of the bunch, 
probably the best overall for the most users.  The Lightning bug is 
much less common than the others, but it and the Blue Racer are BOTH 
much happier at faster speeds, (25 wpm and up).  The Original will run 
20 comfortably.  The Champion is the entry level bug, and will run 
down to 15 or so.  Just adding weight to the existing arm is not very 
effective, and tends to further kill the vibrations even faster.  To 
slow them down, you need to extend the arm, allowing the weight to be 
place further from the arbor.  There are Bug Tamers, (extensions with 
additional weights,) and Vari-Speeds, (a pivoted extension with 
additional weight,) to slow down the faster ones.


The bargains are still out there, but generally NOT on EBay.  I bought 
a like-new Blue Racer from the original owner (1958) at a hamfest about 
three years ago for $25.  I asked if he had priced it, and he said it 
was what he paid for it new and just wanted it to go to a good home!

was that the models with the triangular pivot mechanism (or the

My original deluxe seems to be stuck at around 35wpm with the huge weight

Jason -

I suspect the Sigtomics you are using has a relay to short out whatever 
surge protection device they are using once the initial time period has 
passed.


Here is one type of NTC carried by Mouser.  Essentially they have a cold 
resistance and a hot resistance.  It's a trade off between the higher 
cold resistance to limit the current surge at turn-on, and the hot 
resistance which can be significant if you have a large delta I.   One 
of shortcoming is if the power is interrupted momentarily, there is no 
protection because the NTC doesn't have time to cool off.  Another is 
that they generate considerable heat, and so have to be mounted clear of 
temperature sensitive objects.

I've got the 600/1000W version for amps.  I've used it with my R-4B and

If I knew what make/model of thermistors were in the sigtomics box I'd buy
a few (they can't cost more than a dollar each) and put them in the power
strips.  The voltage does not sag between idle and key down - so despite
my earlier concerns about thermistors and voltage sag it seems to work
quite well.

Hello,

The devices used for current limiting are are cheap, and easy to 
install. The link below is the data sheet for one brand. Note the CL-80 
and CL-90, both work great on most receivers. In addition to providing 
surge protection on start up, the hot resistance is several ohms. This 
will drop the line voltage applied to the equipment a couple of  volts, 
which is more the voltage that they were designed for.


http://www.thermometrics.com/assets/images/cl.pdf

The link below is from Jan Skirrow's site. It explains this type of 
thermistor, along with showing how they are installed in a R-390a. The 
installation for any receiver or transmitter will be similar. Just pay 
attention to what he says about heat generation. A good way to mount 
them is in an external 2 plug  electrical box. They can be bought very 
cheap at Home Depot etc.


http://skirrow.org/Boatanchors/TechTalk3.pdf

I have about 20 CL-80's and 20 CL-90's, if anyone wants one, I will sell 
them for $3.00 each shipped. That is about what I will have into them 
with shipping. I also make some very nice complete units with RFI 
filters built in. They greatly reduce computer and other noises getting 
into your radios. If you would like more information, let me know. I can 
send pictures/specs of the units that I make.


Hope this helps on the thermistor questions.

If I knew what make/model of thermistors were in the sigtomics box I'd buy
a few (they can't cost more than a dollar each) and put them in the power
strips.  The voltage does not sag between idle and key down - so despite
my earlier concerns about thermistors and voltage sag it seems to work
quite well.

[drakelist] SB220 with Drake color

2006-01-19 Thread EOLEEJR



Hello, I thought I remembered someone on this list saying that he had 
made up several front face plates with the Drake coloring for the SB220 amp and 
had a couple left for sale. If someone knows about this, I would appreciate the 
information. Also, any suggestion on the black paint for the cabinet? I already 
checked the archives and did not see it.

Thanks for the help,

Gene / WB4NUM


Re: [drakelist] OT: Difference in Vibroplex bugs

Jason,
Do a Google search. Vibroplex still has a Web-site. They have 
history, old parts diagrams, etc. on line. I think its Vibroplex.com.

Good luck, George

hi,

I sent this to my CW mailing list but there's a much larger audience here
so i'm sending it here as well...


Just wondering if anyone could help me figure out the difference in some
of the various Vibroplex bugs.

I've found about 4 different variations:

Lightning bug
Original bug
Blue Racer bug

And then for the Lightning bug i've noticed some have a square looking
damper for the arm, others just have a post for the arm to rest against.


If I were going to find one of these to buy and USE are there any concerns
using the really old bugs vs. using the new bugs?  I've got a deluxe
original made in 1986 that is quite nice but I thought i'd have a little
fun with some of the really old ones...  but I don't know if the old ones
are more trouble than they are worth.

Thanks for any advice and recommendations.

Jason

The key is that the arm needs to be extended, not just more weight 
added to the existing arm.  Just adding more weight quickly makes the 
action sluggish.  The main advantage of the Vari-Speed is that it allows 
for quick speed changes.

I talked to Vibroplex at the Dayton Hamvention a
couple years ago, and after balking at the high prices
for the bug tamers, they suggested clipping a
clothespin on the arm to slow it down. 


Just one of several suggestions.

Hi Garey et al,

The Vari-speed is the one with the pivoting arm, I
believe. That impressed me the most, although I
believe the gentleman was inferring that the clothepin
could be clipped on at different angles, much like the
Vari-speed. The idea is to increase the length of the
arm, not so much to increase the total weight.

Have fun!
