SB-220 stabilization

In a message dated 96-04-08 05:03:54 EDT, you write:

<< 
Th Parasitic Suppressor Kit for the SB-220 put out by Harbach Electronics
(407-723-7145),  replaces the 1mh grid chokes with  27ohm 1/2w carbon film
resistors and adds 820pf ceramic bypass caps (in parallel with original mica
caps)  to each grid terminal. The single capacitor from the RF input to one
side of the filament is removed and replaced by two .01uf ceramic capacitors
and in series with them are 10ohm 2w metal oxide film resistors - the
resistors connect to each side of the #12ga filament wires for a "balanced
feed".  The kit also includes plate parasitic coils/resistors.

Any comments on this approach??

Hi Bill,
I've never seen the kit, so my comments are limited. A few general statements
are true for all amps. John W0UN has a very good insight into amps, so
hopefully he can add something to this or correct anything I overlook. I like
what John said. It was something to the effect of "Build the amp like you're
going to run it at VHF, and stability problems go away". That should be on
page one, line one, of every construction article. 

Amps develop parasitics because at some frequency the output is coupled back
into the input. The path must have low enough loss, less loss than the gain
of the stage, to make an oscillator. HF tube amplifiers CAN'T become
oscillators without unwanted feedback. It's much better to reduce unwanted
feedback than to reduce the gain. 

In a grounded grid amp, the length and size of the grid(s) and grid leads are
the major players in stability. Better RF grid grounding means more isolation
between the output and input, and more stability.

Adding ANY small thin reactive path from the grid to the chassis is a
mistake. A series capacitor in the grid **always** reduces isolation from the
output to the input at lower frequencies.

Heath made an even more fatal mistake, the put a choke in parallel with the
caps in the grid. That forms a VLF parallel tuned circuit, and the amp, under
the correct load and driver conditions, can oscillate BELOW the AM broadcast
band! The long series path through the grid caps also lowered the self
neutralizing frequency and made stabilizing the amp for VHF oscillation
(generally around the FM band) more difficult. SB-220's on occasion were
prone to **V L F** parasitics, but were stable at VHF. The only problem was
by the time the anode suppressors got big enough to work at VHF, they got hot
on ten meters.

The 220 behaves best with the grids connected to ground with a lug placed
right at each grid pin. Doing this improves stability greatly. Nearly half of
the turns can be removed from the stock parasitic chokes and the amp remains
perfectly stable.

I've never added resistors to the filament RF path, and I see little reason
to do that. I don't know what they do in the anode,  so I can't comment about
that mod. The grids need to be grounded directly, that's an absolute
certainty.

I just can't resist the temptation to jump on this one! In an issue
as subjective and difficult to compare as antennas, how can 
anyone claim that a certain combination is 'best'???

K4VUD came really close, tho. Here is what is 'better' than his
'best'  ;-))


70 feet of guyed rohn 45 with:

    KT-34XA's (2) at 70/40 feet (stackable)
    40-2CD at 80 feet (NOT 82 feet)
    PAIR of phased delta loops for 75 (+3 db gain over K4VUD sloper!)
                                      (+15 db F/B over sloper!)
    Quarter-wave sloper for 160.

Now I'm sure someone else will come along with something 'better'
than my 'better', hi!

...Or maybe:

    36 inch leather strip, 1.25" wide, with two-piece attachment
    point. Perforated in 1 inch spacing for elevation angle
    adjustment. Add dual loops 8 inches offsett from attachment point
    for hanging the 'shack'...

THESE SCORES ARE NOT OFFICIAL!!!   I CANNOT ACCEPT ANY LOGS!!!!!
PLEASE SEND ALL YOUR LOGS TO THE ADDRESS IN CQ MAGAZINE!!

PLEASE READ THIS!! I cannot get your scores if you send them as an 
attached file to your mail. It takes me over 5 minutes just to do one 
score that way. If you do not have the time to type your score into the
text your email, I do not have the time to post it. I have stated this
every contest for over a year and people keep doing it. Also scores that
are sent in without being added up will not be posted. It is a lot easier
for you to add one score up than for me to do a 100. 

The address for the 3830 reflector is 3830 at akorn.net!! Maybe someone can
post on here how to subscibe to it. I am not sure and do not want to put
out any bad information.

Also as I stated in my post before the contest, I cannot do attached 
files. You need to send it in the form of email. Also please state your
full class on it, not just Single OP. If you do you go into the unlimited
class. 

Before everyone starts flaming me about where there scores are, I would 
like to explain. I received a list off 3830 from WZ1R. It only gave me 
classes for people as SO. I know some should be unlimited. If you would
just drop me a note I will be glad to move them.

Subject: measuring coax cable loss
Message-ID: <9604081424.AA21076 at hp-and2.an.hp.com>


Dave, K6LL, posted a note about measuring cable losses with the
antenna connected, using the SWR method.

I'm not sure this method is accurate enough for a contest station.

It is based on the assumption that the antenna looks like a short
or open at some frequency. While this may be a Damn Good Assumption (DGQ)
it may not be an Assumption Good Enough For Contesting (AGEFC).

Consider Dave's example of SWR 7:1, which translates to 1.25 dB loss.

If we send 100 watts down the line, this translates to 25 watts lost
somewhere. Even if the antenna is high SWR at this frequency, It still
seems likely to me that it could radiate 25 watts.

On the other hand, if we're talking long runs of crappy (RG-58) cable,
this loss is reasonable for the cable. But if we're talking 50 feet of
hardline, this loss is unnacceptible. As Dave points out, you need
to consider the expected losses of non-deteriorated feedline. In a contest
station, the expected losses of non-deteriorated feedline is so low that
the antenna's radiation, however low, may be the dominating loss.

In the computer hardware business, they call those the "sync characters".
Another example might be the sending of "nr" before you send the number in
Sweepstakes.
Both are something that are not needed, but can be helpful under some
conditions.

Subject: TS930 ON/OFF switch
Message-ID: <199604081549.PAA06631 at mailhost.worldnet.att.net>

Well I'll be jiggered. Yesterday, I switched on the 930 (my main contest
rig) and the blame thing wouldn't stay on. It seems the on/off switch broke.
It goes in when pushed and the rig comes to life, but when I take my finger
off it, the rig goes off.  Anyone else experience this? Suggestions for
replacement switch vendor? Also, where's a good place to get those little
S-meter lamps?

Thanks, Matt

No, that's not a directive ("Crush All Boxes")...I forgot to note for 
which contests to send breakdown files.  Any of the "big" DX contests 
this season; CQ WW, ARRL DX, WPX SSB.

Thanks!
