Ive been calling CQ for some time, on both 80 and 40. No takers yet, just band noise. Anyone having any luck?

Second Sunday Sprint reminder

John Lonigro
 

Contrary to rumors (started by me), the Second Sunday Sprint does NOT fall on Tuesday this month. It is TOMORROW night, November 13th, from 7:00pm till 9:00 pm CST. To needlessly complicate things, if you are using UTC, then it is Monday from 0100 to 0300. But it will NEVER be on Tuesday.

Please go to qrpcontest.com for details and to report your score. The more people who try to make contacts, the more likely some will get through, and the more fun we all will have. Note that I am one of the worst offenders. "Do as I say, not as I do!"

If I remember, I'll try to send one more reminder tomorrow afternoon, but no promises.

72,

John, AA0VE
QRV from Hutchinson Kansas tomorrow

Paul Smith
 

I will be QRV from Hutchinson Kansas tomorrow as my wife is meeting with her State Association group at the College.

I will use the 4 state frequencies if possible. Give a listen on 40, 30 ane 20

Hope to make some contacts.

Re: Resources to design transcievers

It’s a hard question to try to answer because there’s no one-stop resource.  EMRFD as mentioned below is a good one. W7ZOI announced on the EMRFD discussion group recently that ARRL is discontinuing it. However, in discussions it seems several ham stores still have it in stock. And in further discussion, it now appears that ARRL is going to bring the book back into publication. Whether there will be a revision along with that is not yet known.
 
As others have said, building some simple stuff is the best way to learn. You’ll run into questions you didn’t anticipate and start “writing your own book”. 
 
Web blogs and websites can be good. Especially those where the author discusses how he did the design and problems he solved, rather than just posting the schematic and parts list. For example VE7BPO’s blog (now) and website (earlier).
 
Also useful to the struggling designer are PC based tools.  Especially a free spice program such as LTspice and various filter design programs.

Paul,

See if you can find a copy of Experimental Methods In RF Design by
W7ZOI. It has a lot of design information. It is an ARRL publication,
but is currently out of print.

The ARRL Handbook also has lot of information.

Happy Experimenting.

RMRC cw practice net today

Dale Putnam
 

the RMRC cw practice net will be called today at 2300z on 14.0625 and immediately following on 7.0625 

Bring your comfy cw, and check in. 

See you then!!



Have a great day,

An outstanding effort

Wayne Dillon
 

Good morning all,
Just wanted to say thanks to Paul - N0NBD - for an outstanding effort on 80m last evening, both CW and PSK31. It was a blast to be able to get on 80m with the new antenna but even better to work the 4SQRP nets because Paul has been putting in the effort, thank you sir, thankyou very much.
C U all next week (or on SSS if I can wrangle a pass).

Phil,

I have no idea why I never thought to look a the ARRL resources.

I will look into those chips and the receiver you are suggesting.

Hello Paul,
 
The sources are many; the question is which to look at.
A good starting place might be to check the resources that the ARRL has to offer. Take a look at their website.
 
If it is your first design, I’d suggest that you consider a basic single-conversion receiver with a crystal oscillator.
There you’d need a tuned circuit front end (from antenna), a mixer – such as the NE602 – and an audio amplifier,
perhaps the LM386.
 
You can find circuit configurations (suggestions) for using those chips by using your browser. For example, type in NE602, and you’ll get a
list of websites to look at. Most of the chip vendors include a technical specification and suggestive circuits.
 
Good luck and have fun. One other item. You can use the formulas in the ARRL handbook to figure out what L and C values you’ll need
for each tuned circuit.

Gary,


Thank you very much. I am mostly interested in CW using low power(QRP or QRPp). Not too sure I care which band I start out with, as I want to eventually be able to design a multi-band portable unit.


I really like the modular idea and will probably borrow the concept for my future designs.

Hello Paul, What band, what power level and what mode?

I just finished 25 watts CW on 475 KHZ.....Also, an inexpensive 3450 MHZ
AM design.....Progress is being made on a 22 dollar voice transceiver on
2445 MHZ....

I have done a lot of circuit boards also.....The attached photo shows a 3 board set that can be adapted for roughly 200 KHZ to 15 MHZ CW.....

The small board on the left is the CW oscillator-driver board.....All harmonics are at least 60 dBs down.....

The big board in the middle is the FET power amplifier.....Tuned and also has impedance matching to get a 50 Ohm output.....With harmonics.....

The board on the right is a low pass filter that runs cool and harmonics are down at least 60 dBs.....Runs cool at 25 watts.....

All this on a 4" by 6" piece of circuit board.....

As you can gather, I use all bands and modes of operation.....

If I can help.....Gary...K5QNM...EM36 in Missouri..... garyk5qnm@...

Bob and I struggled but looking at the map I think we were working ground wave! Look forward to working you again Bob, the pleasure was all mine.

I was tickled to get the relay. I will use my doublet next week. It might work better EAST and WEST

Thanks to all and I will see U next week.

Yep I heard you, about 539 to 559, 80 was much better than 40 tonight.
I think I got a clean sweep on 80, CW and PSK31! Kinda vindicates my 124'6" wahr. Great to be back on 80.
