Excess Parts, CA3039 Gone

Bill
 

All,

Anyone who missed the first round of parts also missed the CA3039s;
they're all gone. There's still plenty of PNP Transistors left though. Same
request as before:

1. Email me your mailing address.
2. When the envelope arrives, try the parts. They're old and haven't been
stored for ESD, so try them out.
3. If you like them, put 2 single dollar bills in an envelope, fold them into
a piece of paper to make them more opaque, and send them to me to cover costs.
4. If you don't like them, don't send anything. You're not out anything.

By the way, I estimated poorly; there's only a couple hundred of the
CA3039.

Finally, the cost and hassle of sending these overseas makes this deal
prohibitive for me. US destinations only.

P.S. To whoever sent me a paypal without asking first, I don't want to

and
we'll give the USPS some business.

several thousand each of CA3039 (6 matched diodes, low capacitance, low

2020- wow, what a year. My Happy New Years wish is for 2021 to be much better for everyone.
My special thanks to all who ordered my e-book. Prior to covid-19 I procured my breathing medicine for $10 to $20 a month.
With all the travel and shipping limitations due to covid I am forced to procure the meds in the USA at $98 a month.
Your orders have assisted that without cutting my food budget. Hopefully that will continue in 2021.
See more at QRZ.com /db/W4BWS
So Happy New Year 2021 and for to all have a more healthy, secure and prosperous 2021.
I will be looking for everyone on slow key night December 31 and during January 1.

PCBs for NorCal 2N2/XX Rig

Jim Kortge
 

All,

After a lot of discussion with close associates and thinking through all of the issues with making the PCB available for the NorCal 2N2/XX rig, I've decided not to do it.  Here are the main reasons why.

That PCB is really dense, so much so that many of the support issues I had to deal with came down to builders putting the parts in the wrong place.  In addition, there are 300 parts needed for that PCB, many of which are no longer available, and some of them were quite expensive like the 10-turn tuning pot at nominally $10.00 per unit.

It is obvious to me that a substantial amount of time would be required to find suitable replacements for the extinct parts; I have neither the time nor the inclination to do that for a design that is now 11 years old.  Additionally and realistically, since I was the designer of the rig, most of the support questions would come to me; I've moved on and can't get back into that mode.  When the kit launched, support issues took over my life for most of a year.  I'm going to be selfish and not let that happen again.

Finally, all of the documentation for the 2N2/XX is on my web site: www.k8iqy.com ( http://www.k8iqy.com ) so you can get the docs, build any of the 3 bands Manhattan-style, like I did originally, or make your own PCB using DipTrace or KiCAD with the changes you see fit (like DDS tuning and Digital Display) on a PCB sized to your liking.

So, I hate to disappoint all of those clamoring for 2N2/XX PCBs, but for the reasons above, (and a lot of other unspoken reasons) it won't be happening.

72/73 to all and enjoy the upcoming holidays,

Jim, K8IQY

PS....thanks to all who offered to help out with making boards available, I truly appreciate your support.

Going to moderated mode and postings will be left to die after
14 days in the queue.

End of this group. Take discussions to qrp-l and may the
electromagnetic force be with you always.

Everything up to this point will be left as is until
groups.io decides to start charging fees.... Please
do not migrate files to other groups. They were put

Re: QRPGuys DSB Digital Transceiver

Comparing LA to SF is like comparing an FTDX101 to a QCX. Los Angeles has a population of 4 million spread over a radius of 30 miles. San Francisco is <800,000 people on a small peninsula. Roughly the same as Jacksonville, Austin, Seattle and Indianapolis. It greatly matters what part of any of those cities you use as a comparison. Tourists and business travelers rarely see more than a small subset of any city they visit even over several years. That's not enough time to declare on of the world's largest and most interesting cities as worse than any other city.

Interesting question about the geographic distribution of activity. I wonder
if it's because the West has a lot of "young" people, whereas the East and
Midwest is a little older? I was in CA a month ago and was really saddened
by what I saw in SF versus 20 years ago. The wharf area was still nice, but
get off the tourist areas and it just seemed "dirtier and dingy" to me. I
also saw human waste on the sidewalks, used needles in the gutters, and
people sleeping in doorways...not at all like what I remember from the past.

Oh well, I'd never make it in CA anyway: I'm old, fat, conservative, and

I suspect it is people are just not trying because the bands don't have much
except on contest days.

I use DX Lab with DX Atlas to look at the CW/digital activity. There appears
to be more activity east of the Mississippi than west of it. And there is
more activity east of the Rockies than west of them.

Why??

And I am using GOOD receivers.

The main bands for me right now are 40M and 20M. But I would prefer 40M and
15M. I have a 40M dipole that also works OK on 15M.

It's very true that conditions right now suck compared to the 70's. I had
regular sked's for phone patch traffic between our military personnel
stationed on Guam and the Marshall Islands and their spouses left at home at
Offut AFB (SAC Headquarters). However, poor conditions does NOT mean bad ham
radio. Indeed, one of my club members worked 160 DX stations during the
recent CQ DX contest. It may take a little more effort today than 40 years
ago, but the bands still provide enjoyable QSO's if you want them.

Isn't it odd the bands are moribund at "normal" times but are actually
crowed on FD and other popular contests. Hmmm. I wonder...How much of this
"The-bands-are-horrible" crap is because we turn on the radio, tune around
for five minutes and, not hearing anything, shut down everything just so you
can go upstairs and rearrange your sock drawer. I wonder what would happen
if every one of us tuned around for five minutes and, not hearing anything,
called CQ for five minutes before giving up? I'll bet you'd make a contact
more often than not...especially if everyone else was doing the same thing.
I know the science and the sun's being pretty crappy about things at the

Part of the problem with ham radio today is ready built radios are too
expensive for a lot of us.

70 years ago we could buy a surplus BC-453 (Q5'er) for $5 and build a
converter to put in front of it for another $10.

Not so today. And the kits like Heathkit are long gone.The Heathkit low
power transverters (HW-7, HW-8, HW-9) all go for several hundred bucks on
eBay. And they are just direct conversion receivers.

A good starting point is the NorCal40. It's single band but it's pretty
cheap. And PCBs have been available.

Now is not a good time for ham radio. We are at the low point of the solar
cycle. We may have just started Solar Cycle 25. I think partially because of
this the ham radio activity is at a low point.

If you don't have a GC receiver there are a lot available on eBay. I like
the Heathkits. I have mostly tube types but I do have a couple solid state
units.

They will let you listen to the activity on the bands.If you don't hear any
activity on one of these you won't hear any on your QRP kit.

It doesn't hurt to have a signal generator.

I second the notion. Build it, use it and see what it does.

I built the kit and put it on the air and worked almost 30 Qs with
it. I am not a fan of the mode after the fact. You just point
and click and get a simple exchange. For $40, you do get something
that does work.

You guys remember the pixie? Did you get it to work as well?

And, going back to the QRPGuys kit. I never received a follow up
email saying I was causing problems by being on the air.

I have, in the last five weeks pulled a Brian May, of Queen fame,
by doing over 4,000 lines of C code and two books with more in
the queue and gone back to doing physics. I have downsized the lab.
I spent 26 years doing QRP stuff and it's time for me to devote time to
doing physics seriously again. I've a bunch of papers to publish
that I have done over the past 20 years.

The EMRFD group has gone. It is time for this group to also come
to and end.

I do not want this group to turn into a bashing group. Too many people
have their own agenda.

This group is coming to its end of life. At the end of the year I will
disable all posting, but the material files and messages will remain
intact for the duration of the life of groups.io as long as we are not
charged for the use of the space. Greed seems to be kicking in on
the Internet and every one wants to make money.

Feel free to start a qrp group with another name and announce it here.
I will not release control of the group as I did with qrp-l. I don't
want any attacks made on me for this decision. I am in control.
I control the vertical. I control the horizontal.

Hopefully the run was worth the humongous amount of time and energy
I spent on projects and trying to stimulate the group. I kept the
20m 5W xcvr and will be on 20m trying for DXCC before I go deaf. :-)
It's the last thing on my bucket list for ham radio.

I use DX Lab with DX Atlas to look at the CW/digital activity. There appears
to be more activity east of the Mississippi than west of it. And there is
more activity east of the Rockies than west of them.

Why??

And I am using GOOD receivers.

The main bands for me right now are 40M and 20M. But I would prefer 40M and
15M. I have a 40M dipole that also works OK on 15M.

Re: QRPGuys DSB Digital Transceiver

Jack
 

Interesting question about the geographic distribution of activity. I wonder if it's because the West has a lot of "young" people, whereas the East and Midwest is a little older? I was in CA a month ago and was really saddened by what I saw in SF versus 20 years ago. The wharf area was still nice, but get off the tourist areas and it just seemed "dirtier and dingy" to me. I also saw human waste on the sidewalks, used needles in the gutters, and people sleeping in doorways...not at all like what I remember from the past.

Oh well, I'd never make it in CA anyway: I'm old, fat, conservative, and don't like avocados.

All this is specious to me. If it was a kilowatt kit with the likelihood of
hundreds of them operating simultaneously all over each band, then maybe it
an issue. It something to experiment with for those who have the talent and
time. Personally, other than knocking off awards, the allure of FT8 puzzles
me. On the other hand, if someone is upset with the fact it's DSB, perhaps
it will lead to hacks that cheaply change it.
If you bought one, built it, use it. If it becomes a real issue, I'm sure
we'll hear about it. Until then, let's put the cart back behind the horse

and click and get a simple exchange.  For $40, you do get something
that does work.

You guys remember the pixie?  Did you get it to work as well?

And, going back to the QRPGuys kit.  I never received a follow up
email saying I was causing problems by being on the air.

I have, in the last five weeks pulled a Brian May, of Queen fame,
by doing over 4,000 lines of C code and two books with more in
the queue and gone back to doing physics.  I have downsized the lab.
I spent 26 years doing QRP stuff and it's time for me to devote time to
doing physics seriously again.  I've a bunch of papers to publish
that I have done over the past 20 years.

The EMRFD group has gone.  It is time for this group to also come
to and end.

I do not want this group to turn into a bashing group. Too many people
have their own agenda.

This group is coming to its end of life.  At the end of the year I will
disable all posting, but the material files and messages will remain
intact for the duration of the life of groups.io as long as we are not
charged for the use of the space.  Greed seems to be kicking in on
the Internet and every one wants to make money.

Feel free to start a qrp group with another name and announce it here.
I will not release control of the group as I did with qrp-l.  I don't
want any attacks made on me for this decision.  I am in control.
I control the vertical.  I control the horizontal.

Hopefully the run was worth the humongous amount of time and energy
I spent on projects and trying to stimulate the group.  I kept the
20m 5W xcvr and will be on 20m trying for DXCC before I go deaf.  :-)
It's the last thing on my bucket list for ham radio.

LOL at Randy's post.

QRPGuys aren't the only ones out there with a DSB FT8 kit.  People need
to
get over all of this.  It isn't meant to be a serious radio, it could be
very fun to play with like others tinkering around with DSB voice
circuits.

Mine is on the bench and I will use it.

JIm,
It was phasing and also could also do AM synchronous.

All this is specious to me. If it was a kilowatt kit with the likelihood of hundreds of them operating simultaneously all over each band, then maybe it an issue. It something to experiment with for those who have the talent and time. Personally, other than knocking off awards, the allure of FT8 puzzles me. On the other hand, if someone is upset with the fact it's DSB, perhaps it will lead to hacks that cheaply change it.
If you bought one, built it, use it. If it becomes a real issue, I'm sure we'll hear about it. Until then, let's put the cart back behind the horse again.

Bob,

That is totally correct unless you are in the first 100khz.
