Cancel XG3 morse tx?

Stan Gibbs, KR7C
Is it possible to cancel a morse code transmission initiated with the "W" command?

Re: Cancel XG3 morse tx?

Stan Gibbs, KR7C
Is there any chance we could also get a command to determine whether Morse transmission is active?

K3 power supply recommendations

tbranton
Good morning everyone ,

I think I have found a very nicely maintained and equipped K3 to purchase. Any purchase recommendations as to a well constructed and trouble free power supply?

Thanks

The K3 in question is a K3/100.  Thanks,

GM Tom:  I've found the Astron RS-35M to work just fine except that the
light in the ampmeter went out and I would have to replace the complete
meter to resolve the problem - so I just ignore that meter.  Otherwise it
just keeps on working and has been on  14 to 16 hours per day since I got it
about 3 years ago.

Re: K3 power supply recommendations

Joe Subich, W4TV-4

Depends on the version ... some pots are mounted vertically,
some flat, some have holes in the board to adjust through, etc.

My preference is the RS-35A ... the non-metered version.  I find the
metering not that accurate.  Since the supplies are mounted below
the bench and I usually get the DVM when setting them up, I don't
see a justification for the added expense <G>.

Re: K3 power supply recommendations

One of mine is over 30 years old ... it gets opened about one
a year to have the dust blown out, have screws/bolts checked
(filter cap terminals, etc.) and the output voltage gets checked.
Never a bit of trouble ...

My newer unit is perhaps five years old ... it gets the same
treatment also no problems.

Re: Cancel XG3 morse tx?

In reply to this post by Stan Gibbs, KR7C
Hi Stan,

I spent a little time investigating adding these features to the XG3 firmware.  It may be possible for me to add the ability to interrupt 'W' Morse sending with any received serial character or key press.  However adding the ability to detect when Morse is being sent (i.e. adding another field to the Info command) would require quite a bit more programming which I cannot devote to at this time due to existing demands.    

73,

Paul

If it ain't broke ... just open it up, blow out the dust, and tighten all of the screws
that connect the capacitors to the board. Then make sure the bolts on the output
connectors are tight, too.
Then settle back and use it for another 25 years.

I use either my Astron RS70M or my RS35M at my shack in San Diego. Both are really great. I got the larger astron for use with a couple larger mobile solid state amps and my TS480hx.

I also have a powererx 30 amp power supply and a RS35 (no meter) at my other shack in Texas. Both of those power supplies work well also.

Re: K3 power supply recommendations

Jim Wiley
In reply to this post by Bill Clarke
Bill -

Older Astron power supplies can continue to give good service, there is
no reason to replace it unlessit seems to have a problem.

One of the things that does go bad in these supplies, particularly ones
of this vintage, is that the main filter capacitor "loses its
microfarads"(dries out).  The capacitor has to handle a fairly large
ripple current, especially if the power supply is working hard, and that
in turn can have detrimental effects onthe big capacitor.   I recently
encountered a RS-35A with exactly that symptom, the power would dip
momentarily at voice peaks when running a 100-watt transceiver.  The
voltage was fine for receiving and anything less than full output, but
when  a big voice (or CW) peak came along that demanded more than about
16 amperes from the supply, it lost regulation, which caused all sorts
of weird and wonderful things to happen to the transceiver -such as loss
of PLL lock, frequency shifting, mode shifting, and so on. .

The cure was to replace the 30,000 uFd / 30V capacitor in the RS-35A
with a newunit.  As it turned out, new capacitors of that exact
specification were a bit hard to find, and expensive, but a search of
theMouser catalog turned up a great choice. I found a 33,000 uFd / 35
volt unit for a reasonable price (about $35.00 including priority mail
postage).  The new cap is both a bit smaller (physically) than the
original, and has significantly better specifications.  The Mouser part
number is 647-LNT1V333MSE.  The new capacitor has the same connection
terminal spacing, so the control board just bolted on.  I did mount the
board slightly differently, but that is justpersonal preference.  The
original mounting method will work fine.

Here (I hope) isa direct link to the Mouser catalog page:
647-LNT1V333MSE
<https://www.mouser.com/Search/ProductDetail.aspx?R=LNT1V333MSEvirtualkey64700000virtualkey647-LNT1V333MSE>

Result: The oldAstron gets  new lease on life - it works just like brand
new, and I expect may more yearsof service.

Perhaps the Astron RS-35A that you have is still working OK, but it may
be getting a bit creaky, so to speak. Replacing the main filter cap
can't hurt, and will go a long way toward insuring trouble free
operation for years to come.

YMMV, of course. No connection with any vendors or manufacturers, just
satisfied with the results at what I considered a fair price.  Any yes,
I thought about some of the large computer power supply caps that were
in my junk box, and I might have tried one if it was "close" - but after
a bit of thought, the new unit was a better choice and might in the long
run prove to be less expensive.  Asurplus unit could have its own
problems, possibly causing a more catastrophic failure.

Re: K3 power supply recommendations

In reply to this post by Mike Reublin
I have a question on adjusting the voltage a bit higher for use with the
K3. I was thinking of 14.5 V, as others have mentioned, and adjusting
voltage on receive.

I have an accurate voltmeter.

Should I set the voltage with the voltmeter measuring at the DC input to
the K3 (at the power pole into the radio) or should I use the internal
voltmeter in the K3?

Use your meter.  BTW, I second, third, fourth... the recommendation of the RM-35.  Mine has been converted to a "smart charger" that keeps a 95AH AGM battery charged, but before that was used normally without incident.

I have a question on adjusting the voltage a bit higher for use with the
K3. I was thinking of 14.5 V, as others have mentioned, and adjusting
voltage on receive.

I have an accurate voltmeter.

Should I set the voltage with the voltmeter measuring at the DC input to
the K3 (at the power pole into the radio) or should I use the internal
voltmeter in the K3?
