Thanks for all the feedback. Yes, I built the cable that came with the it
and I am definitely going to use it put the 9 pin to USB on the end of it,
I know you  cannot any other 9 pin cable.
Also I will get a proper cable with a good chipset to take it to USB.

[Elecraft] KIO2 RS-232 to USB?

[K2bew]

My computer does not have a 9 pin serial port. I have a 9 pin to USB
prolific cable/adapter that I use to connect my Ten-Tec RX320, that also
has a 9 pin serial port, to the computers USB.
The manual for the KIO2  says you can use a 24 pin to 9 pin adapter, but it
does not mention connecting to USB. Since the cable is so specialized for
the KIO2 to K2 can I connect it with the 9pin to USB prolific cable? I
don't want to short anything out etc...

Re: [Elecraft] K2 VCO Alignment T5 L30

[K2bew]

Don Et Al,
So, It is with some embarrassment, and much relief, that I can report it
was operator error and my BFO is now working perfectly.
I got home from work and was getting ready to do some continuity checks to
all the circuits surrounding and including U11,  but decided I better check
all the components again in that section with the RF board disconnected and
out of the case.
I found much to my chagrin I had not installed D37 and D38! I had them
checked off in the manual as being installed, and I even wrote in pencil in
the margin on the next step where you put the rest of the V149's in the RF
board that I had 2 left over, but I failed to notice I had them left over
because I did not put them in the step before!, good grief.
Anyway I have a high BFO reading of 4917.60 and a low reading of 4911.98
with a difference of 5.62.
Thank you Don and to others that gave suggestions, and I do wish those
having similar problems well in their trouble shooting.

Upward and onward 73,
Tom Bewick, K2BEW

Re: [Elecraft] K2 VCO Alignment T5 L30

[K2bew]

Don et al,

I tried a 15pf cap ( what I had on hand) at the source of Q19 to ground and
I got .025v on R30 that did not change with the adjustment of L30,
essentially no voltage.
So, I took it off and it went back to 4.5 volts. So, then I tried Vicenç,
EA3ADV's suggestion and I put 17 turns on the red wire of T5.
That got me a voltage of 8.5V on R30 with L30 bottomed out that I was able
to easily back off to a stable 6 volts.
I went ahead and did the voltage tests on the other bands and had a nice
range of 1.844 to 6 volts as my low and high on the VCO.
So, that's all set.

However, new problem. I went on to the test the BFO and I have .04 kHz.
on TP2, so it's not working.
I went to the trouble shooting guide and I have 0.058 Vrms on pin 6 of U11
with the RF probe.
Looking at the archives of the reflector that would indicate that U11 is
bad and I need a replacement, correct? or are there other things I should
look at first?
The good thing is I'm becoming very accustomed to the radio and enjoying
the trouble shooting.
Thanks for all the help, I really appreciate it.

73,

Thanks a lot Don and Ed,

I will be working on it over the weekend and will report back.

[Elecraft] K2 VCO Alignment T5 L30

[K2bew]

Don et al,

Since I know Don monitors the reflector as well as the support emails,
rather than email Don directly I thought I would ask the question on here
because I know I always find it helpful to read other peoples questions on
here and Don's answer.

Building the K2 I am at the VCO Alignment voltage check on R30 and
adjusting L30.
VFO frequency set at 4000.00 kHz
I initially got 3.5 volts and bottomed out L30 to get it to 5.5 volts, and
then I over screwed it to try to get that last half a volt and ended
damaging it, so, then I carefully took out L30 and put in a new one.

I also took out T5 and rechecked all the ends for continuity, rewound the
green wire to space it exactly in the middle of the red winding and spaced
everything evenly. I confirmed it is the large yellow core, I have 16 on
the red wire and 4 on the green (by the way the illustration shows 14 turns
of red) . I verified I have R30 as Br-R-Br 120 ohms with both my DVM and by
color, and I verified C72 is 271, and I reflowed the solder on both.
With a new 4.7 inductor (large slot, no red mark) in L30 I now get 2.75
volts on the left side of R30 to start with and it bottoms out at 4.5 volts
(I was very careful to not bottom it out too hard this time and damage this
one, and I have already ordered a couple new ones from Elecraft).

What else can I do to increase that voltage? Would changing the number of
windings on T5 change it enough to get to 6 volts?

Thank you and 73,
Tom Bewick K2BEW

Re: [Elecraft] OT: WWV/WWVH Closure

[K2bew]

Sorry don't agree at all. Emergency communications when everything is down
and people need help is not comparable to a transmitter that puts out the
time according to an atomic clock over radio. You can always use a sundial,
and knowing the time to the second is not necessary in an emergency.

Re: [Elecraft] OT: WWV/WWVH Closure

[K2bew]

I don't think John was implying people didn't have or use wwv clocks, but
that's it not a reason by itself for WWV, and I agree with him. Why pay
thousands of dollars to staff and run wwv just for clocks and stuff? With
the internet and phones that use data and or GPS satellites to constantly
synch time more effectively than radio sygnals it does seem crazy to fund
it. Not to mention that Canada has the equivalent already in CHU.

Re: [Elecraft] Leaving the Reflector

Why do people leaving a list always have to announce it? To make sure
everyone knows how good they are and how bad everyone else is that's left
so that we can all feel bad? Sorry I don't, had nothing to do with why you

Why not just unsubscribe without announcing it?

Re: [Elecraft] K-Line Climate Control

[K2bew]

Just buy a few old tube radios off eBay to restore that were stored in
sheds or garages and look at the all the corrosion from condensation inside
them and you will have your answer. Not a good idea unless you climate
control the shed.

Re: [Elecraft] K1 and K2 RIP?

[K2bew]

The K1 was discontinued a while ago, I just bought a k2 over the summer
after the K1 was discontinued out of concern the K2 might be next, this is
the first I have heard the k2 was discontinued however.
Hope not,  it’s the only one on the market like it that you can build
yourself, we can only hope that perhaps they will come out with new kit

Re: [Elecraft] K1-2-Band-Module for sale on eBay...

[K2bew]

I occasionally sell on eBay and I have one simple reason for Conus only.
Packages sent out of the US cannot be insured, at least through USPS, so if
they are lost or damaged you have no recourse.
Maybe that’s not true of private shippers I don’t know.
As far as PayPal protection they almost always side the buyer, not the
seller. I don’t believe they offer any help if your package is lost or
seriously damaged, in fact it’s usually the  opposite, if a buyer gets
something damaged then you as the seller are forced to refund all the
money. So, if it is uninsured because you can’t get insurance if it’s
shipped out of the US, your out the item and have to pay the buyer back.

Re: [Elecraft] Elecraft Hex Key worth?

[K2bew]

There is a big difference between what someone asks and what someone is
willing to pay.
There are overpriced things on eBay posted all the time by people trying to
flip them just to make money.
I shake my head many times over the prices I sometimes see things listed
for.
If your going that route just list it as an auction starting relatively low
and let the market set the price.
