While discussing Astron. Last night I thought my 50M was biting the
dust..every couple of minutes it would hum and literally vibrate the entire
console. After 5 years with it...well...it's time. NOT...I had plugged in a
Pelonis ceramic furnace heater for my cold feet (bad circulation I
guess)..and every time the Pelonis kicked on, obvious voltage drop and major
hum and groaning agony from the Astron..Just FYI in case anyone decides to
share an outlet/same circuit with a demanding load. The Pelonis is a
fabulous product..just not in tandem with the Astron. 73, Tommy WD4K

One more item about keying and I'll keep quiet. !!!!!!
Keyer mode A and B reflect the Curtis Keyer A and Curtis Keyer B timing
patterns. There is, or should be, quite a bit of difference in keying
characteristics. If it changes modes on its own, you MAY have a problem.
I think Ten Tec's choice of Curtis Keying was an excellent move as it's one
of the most user friendly modes available. The Curtis A timing (in the
Orion) is slightly superior to Logikey's VZero timing. Now please
understand, this is only my opinion as I'm sure others would prefer the
Logikey over anything. The Logikey is an excellent keyer, I just like the
Orion's better.

I have heard advice to ground the negative pin - never did it.
Mine is on the floor -- under the desk -- and I leave it on all the time.
After three years, it is still happy.
If you power on your radio by leaving it's switch "on" and turning your
power supply on and off, you may be getting a surge the radio is not
liking. Try
turning on the power supply first, then the radio.

Most power supplies today have excellent regulation and to accomplish such,
provide for the voltage to ramp up from zero to the operating value over a
period of time. Now this time period may a 0.1 sec or so, but it is not
instant. Some actually use longer ramp times in the order of 1 to 2
seconds. I really don't think today's regulated power supplies "surge on"
or provide a surge at power on. At least I don't want one that does.
With that said, equally, the microprocessor MP circuits require the voltage
Vcc stable before initialization of operating parameters occur. They too
have timing circuits which delay the initialization until the power Vcc has
settled. These timing values are established by the circuit design often by
external components as simple as a series RC circuit.
Take a situation where the MP circuit begins it initialization in 0.5 sec
and the power supply ramps up in 0.8 secs. overall. Certainly viewed as a
situation that will not be happy with the MP and the operating instruction
will most likely mis-load due to the power supply changing voltage over a
0.8 sec interval and the MP ready to load at the 0.5 sec mark.
SOLUTION: Be sure the radio is off, turn the power supply on and allow it to
settle for some 1 to 5 sec and then turn the radio on. All will be happy.

Or just leave the supply on (and turn the rig on/off when needed). I
left my RS35M on 24/7 unless I was going on vacation and going to be away
from the house for a long period of time. Never had a hiccup.

You've got me intrigued now, Don - I may plug my paddles into the Orion
this weekend (in between bouts in the BARTS contest) and try that keying
out for myself.

After 54 years at it, I?ve decided I?m tired of ham radio.
As a result, I?ve decided to offer for sale my Corsair II, which
is very clean and from a non-smoking environment, and has all
three extra filters (1.8, 500 and 250). I?ve changed the
bandswitch knob to one that has a brass sleeve (the original
cracked and became unusable) and as far as I know there are no
other mods to the rig. I bought the Corsair from a ham in New
Brunswick in 1997 and sent it to TenTec to be checked out (one
loose connection) shortly thereafter. It?s worked well, both on
QRP cw and full-power SSB, ever since.
Also have a clean 961 power supply.
And the third item is an MFJ 784b DSP unit, which makes a
terrific addition to a Corsair station since it smoothes out the
cw sidetone and provides significant noise reduction, nulling of
unwanted carriers on both cw (manual) and phone (automatic), and
an almost infinite choice of bandwidth selections.
Asking $525 U.S. plus shipping for the Corsair II and $140 U.S.
plus shipping for the 961 supply. These are offered as a package
unless someone just wants the Corsair II. I don?t wish to sell
the 961 supply separately unless the transceiver goes first.
Asking $150 U.S. plus shipping for the DSP unit.
Manuals supplied for all items.

Howdy Bruce:
I had the same kind of problem with my Astron RS50M when I would power it
up......I would trip the breaker in my house power panel most times.
I called a tech at Astron and they said installing an MOV would solve the
problem. I don't recall if the MOV went across the transformer primary
winding or not...just can't remember.
I ordered the MOV from Astron and after installing it my RS50M never tripped
the breaker again.......problem solved.
Call Astron and describe your problem and ask them if an MOV is required.

I use the Astron 35 amp here and never turn it off. I've never had a
problem of any kind. I use the on-off switch on the radio (Orion) and
all boxes are grounded together on strap. Ona very few occassions I have
come home and found that a nearby lightning hit has tripped the overvolt-
protection in the Astron, but other than that since 1985 that ole beast
has been hummin along. There may be some revisions in the supply since
then which may change the picture.

I've found a lot of this O-2 keyer discussion interesting.
My take on it is that it doesn't take but a very small change in keyer
timing requirements to throw things off. We're creatures of habit if
nothing else -- I suspect like a pianist plays Czerny's "The School of
Velocity", we send CW out of very low levels of the brain, and perhaps lower
than that. There are no "fore-brain" functions involved once we get past
language and down to the level of finger twitch on the paddles.
Until a few years ago, I'd been using a WB4VVF Accu-Keyer with auto
character spacing that I built back in the 70's after the first article
appeared in QST. Although I tried to update several times, everthing else I
tried "had timing problems". I finally bought a K4, and even though it has
an "accu-keyer" emulation mode, it still just wasn't quite the same as the
original. I almost went back to my little homebrew box.
Ultimately, I bit the bullet and spent enough time with the K-4 to retrain
myself. So, although it was slightly broken when I got it, it magically
works fine now :-)
Don't really know if there's actually an issue with the keyer code in the
Orion/II or not, 'cuz I don't use it. But perhaps it just requires
"familiarity" to fix whatever bug seems to be there ....

Bruce -
I used the shift info in the manual to set "things on the nose" in my
Paragon.
You have to use an external voltage source, say plus 9 V, to have shift high
and
-9V to shift low. The manual will set you straight if you keep this in
mind.
I used 9V because I made a small battery changeover circuit with a slide
switch
in an Altoids box to have +9V or -9V as selected to a RCA connector which
fesds the Paragon. Its a Paragon 2 in my case. Same thing for the original
rig.
Hope this will help out, OM.

I run my Argo V off the TT 937 supply, which I leave on all the time and

"The School of Velocity"? I was going to say that !
I am wondering if the RF gain control affects the AGC threshold on the O2.
I suspect it does.
