Fb on the Alex Loop, sounds like a good DF loop. Bet quite a few of the guys have them or another magloop. The hunt is on! 72 WAØITP I love this radio stuff. www.wa0itp.com www.4sqrp.com On 2/8/2017 3:45 PM, dekle wrote:

Terry,
I just looked at the "Snoop Loop" you referenced
and it got me thinking.
I realized that I already had a DF loop - the Alex
Loop.
Although it is bigger and requires a receiver, it can be
easily hand-held.
I tried it with a HB-1B and it works great.
The null is broadside to the loop and very
sharp.
It doesn't have front/back directional discrimination,
but with a little triangulation, the Hidden Oscillator would be easy to
find.
A little team work would be an asset here, but the
"team" will have to decide who gets the prize.
Thanks for the reference!
Bill

Hot IRF510
I am finding that my reverse voltage IRF510 is running hot enough to burn my fingers, even when the BJ is switched off. I was questioning why my Jet Ski battery was running down after a few days of "just sitting on the bench" while connected to the turned off BJ.
Any suggestions? Also the receiver oscillator transistor seems to be the temp sensitive wandering part. I sprayed lightly each part with coolant air and that part seems to move frequency the fastest and the farthest. The toroid is also temperature sensitive but less so. Dave K8WPE Dave K8WPE

Ocon Oscillator Hunt
WA0ITP
I'll try again, didn't see
the first post.
Just ran across this article on direction finding antennas. Some versions look easy to build and would be good for the Ocon Oscillator Hunt. The Snoop Loop abt halfway down the page looks quite good for our purposes. http://www.ce5prd.cl/documentos/antenna_handbook/14.pdf 72 WAØITP I love this radio stuff. www.wa0itp.com www.4sqrp.com -------- Forwarded Message --------

4QRP email blog 2017-1
4QRP The original email blog of the 4SQRP Group -- copyright February 2017 Walter - K5EST - Editor This coming weekend SSS Second Sunday Spring February 12th The Second Sunday Sprint is this coming Sunday, February 12th, 7:00-9:00 pm CST (Monday, 0100-0300Z). The rules are simple. Go to the 4SQRP website <http://4sqrp.com> and click on "4SQRP on air activities" Scroll down to the bottom of that page and you will see a summary of the rules, plus links to where you submit your score and where you can get the complete rules. If you tried to participate but nobody heard you (or you heard nobody), feel free to enter a score of 0 points, as long as you made an honest try for at least 15 minutes. Obviously, reporting a score of 0 is optional and won't affect anything, but it will give me an idea of how many people are participating. I don't have 80M capability, but I understand 80M has been more friendly than 40M lately. It might be worth listening down there for a while. 72, John, AA0VE 4SQRP Contest Coordinator OzarkCon 2017 With less than 50 days until the pre-registration ends to the Premier MidWest QRP Conference, OzarkCon, please do not wait to pre-register! Do it now :-) PrePaid Registrants will receive the following items in your package at the Registration desk when you arrive in Branson: 1. Tickets for the prize drawings (two per registration) 2. Meal tickets for the Friday night banquet dinner (if you ordered them) 3. Souvenir callsign and name ID badge (if pre-registered and paid by the dates indicated on the website) ALSO an OzarkCon FIRST..... The Hidden Oscillator
At the conclusion of the prize drawings on Saturday I’m going to activate a small rf oscillator and hide it somewhere in or around the Stonecastle. The person that returns it to me will receive an unbuilt Hy-Per-Mite* audio filter kit as a prize. The oscillator is set to approximately 7116.5 kHz and it switches on for about 1.5 seconds and off for about the same amount of time. You will be able to hear it with your cw receiver. (Actually it’s possible to "hear" it with just a portable AM shortwave receiver but during the ‘on’ time it will just quiet the receiver and you won’t get the nice CW note without a BFO). I can hear it with my County Comm GP-5/SSB receiver 125 feet away. I’ll let it run until someone finds it or until I have to leave on Sunday. It will be hidden in a “common” area that is accessible to everyone at any time. Nothing will have to be disassembled and nothing of any major consequence will have to be moved to find it. It will be stationary and its retrieval will not require you to be in an unsafe situation. Good luck.......73, Bill - KV6Z Dummy Load QSO Party at O'Con Be sure to bring along a portable rig, a dummy load and some QSL cards. There will be a fun operating event at the Stone Castle to make some QSO's on a dummy load. Suggested operating frequency is around 7040 and 7122KHz CW. Special event station KØN will be on the air as well as WQ5RP on the dummy load. Make a QSO with KØN or WQ5RP and bring your QSL card to the station to be entered into a special prize drawing! Terry, WA0ITP has provided some info on the OzarkCon Dummy Load Special Antenna that might be helpful to increase your signal strength. Check it ot on Terry's web site. The Bayou Jumper Have you heard a "Jumper" on the air? This popular nostalgic kit has a huge following. Being "rock-bound" (crystal controlled) dread has sure changed over the years. The rock-bound has become an on the air status symbol. I hear operators moving frequencies to accommodate the the crystal bound stations. Seems like the nautical rules ......power boats give way to sail. The rig has a socket for the old-style FT243 crystals, plus 7030 and 7122 kHz crystals and included crystal adapters. If you have old 7MHz Novice crystals, you can use them with this rig! AND only one toroid to wind in the receiver, and none in the transmitter. Only ONE for the whole rig! To order your Bayou Jumper before OzarkCon, see http://www.4sqrp.com/bayouJumper.php SMALL ........but Not a Magnetic Loop Antenna Maybe you remember the ole time twin lead vertical. How about a coax non-magnetic loop that is small and has some possibilities. My first loop was worth more experimenting. Best part is that NO butterfly capacitors or vacuum variables are needed :-) See: dit 72/73....Walter Dufrain - K5EST

Finding it will not be
easy.
You'll need to be resourceful, creative, and, to some
degree, lucky.
Imagine that it's a transmitter operated by the ICOBG*
and it's sending instructions to the submarine fleet off the coast of
Kansas.
It's your job to find it and prevent global
destruction.
There's trouble at the Old Mill.

Re: Pixie success
Curt
I own several of the Pixie genre including a Tixie, Lil Squall, Sea Squirt, Tiny Tornado, and one of the Chinese clones. They have always interested me from the minimalist aspect. Have made a lot of QSOs with all of them as far as 1000 miles, very few 2xPixie QSOs though. Never had one receive 20M and 40M at same time. Would be happy to QSO with you, but none of mine would make 7.118. If you post on QRPspots when QRV I can call you with the K1.

Pixie success
Dennis Schaefer
I bought an assembled Pixie from eBay. It was in a little plastic box and only cost a little over $7.00. The Pixie is definitely a novelty rig, but an actual transceiver for $7.00 with free shipping from China can't be resisted.
I hooked up the antenna and heard lots of signals. It would hear many signals on 7.023 that my big rig wouldn't. I found out the reason was that it was simultaneously receiving on 7.023 and 14.046, with about 3 KHz bandwidth on both frequencies. Lots of very high CW tones! I put a 40 meter external bandpass filter in the line and was able to have a QSO with WA5BDU, who is about 7 miles away. I also made a contact with BDU on my Ham-Can. I built this a couple of years ago, but never got it to work. Some careful attention to solder connections finally made it work. I'd like to get a QSO out of the local area, so I'll listen on it and see if I can snag anyone. It is not on 7.122, it's more like 7.118. Now to get the controls hooked up on the 20 meter One Watter I got from WK8S.... 73, Dennis, W5RZ

Re: Preferred tone frequency
Bill Cromwell
Hi,
toggle quoted messageShow quoted text
We should setup our radios for whatever we prefer. If there is no adjustment as Curt has mentioned we should use whatever that produces. I have one that is not adjustable and is 600 Hz. I dial the incoming signal to 600 Hz on my waterfall and *go*. I may install RIT on the rig to get me to my preferred 500 Hz. More likely I have better things to do so 600 it is. 73, Bill KU8H
