FOXHUNT: Fox alert!

Dale Putnam
 




 

FOX ALERT!  
There are two Fox that are reportedly on the prowl.. and they love to tangle with hounds.
They have been reported to be heading into the 40 acre woods... and reportedly will be
seen somewhere between the trees marked 7.030 and 7.050... and this all comes to a
head about 7pm MT (0200z) Tuesday evening. ALL available hounds are encouraged to 
come help mix it up with these two sly and wily Fox.... W9CW and WC7S are on their badges
printed in the foxhole by the  Foxhole Certifying Committee. These two are known to be 
very agile and sly.. and extreme skill may be exhibited by them, care and caution is advised.

ok.. now for the serious stuff - 
1.4 The 40M Foxes will operate within +/- 10Khz of 7.040 MHz.  
That does NOT say anything about where the HOUNDS are to be.....

So be alert, and pay attention to the directions the Fox gives... 
What does the Fox say?   is a good line to remember.!!
Also.. one other aspect may be helpful, the fastest way to get through the pack,
is to get YOUR call heard by the Fox... and the BEST way to do that.. is to put YOUR call.. 
in the CLEAR.. either by giving your call at a time when NO one else is.. timing.. or by
putting it on a spot that does NOT have anyone else there...   IF you are in the middle of the 
pack  -  TIMING is a critical concern... if you are spread away from the pack even just a little..
calling additional times allows the FOX to tune to you... 
So there are two different strategies.. call often??? get away from the pack.. 
Call once>>> time it right and put it right in the pack. 
DON"T do both at the same time... but switch back and forth is good too.

Good Luck to all and to all a good HUNT!!
Catch us if you can...

Navigating the Yahoo Group site

James Compton
 

Is there a way to enter a search in a particular group for a subject instead of having to scroll through pages of conversations and topics?  I've tried to type in a subject to see if it's already been discussed, but haven't had any success yet.  As much discussion as in this group, it would be probable that some topics I have questions about have been covered before I joined the group.


Inductor types and applications

James Compton
 

I'm going to build the Elliptic Low Pass Filter shown in the 4SQRP SAVXO article "How to Put  the SAVXO on the Air and be Legal" .  The schematic shows L1 as 0.9 microhenry and the picture shows a toroid.  My question is: can an air-core coil inductor be used instead of a toroid?  

By extension; a general discussion of inductor types would be very helpful for some of us who are not electronically savvy.  In general, what are the advantages/disadvantages of using toroids in simple circuits, ie., simple qrp transmitters, low pass filters, etc., instead of air-core coils.  Also, can manufactured inductors (I recently purchased some from Mouser shaped like high-wattage resistors) be used in place of toroids as long as the inductance values are the same?  

I know there are basic differences in inductors, even when their inductance values are identical. Since air-core coils are so easy to build, I need to know their limitations in simple qrp applications.
Thanks!

In our specific case here I do not believe the poster intended anything nefarious. Just excited to share some information and may not have done enough due diligence.

I totally agree that in general the ham radio community are honorable and honest. QRPers are of course some of the best folks around!

Hi Glen,
 
No not all, but we do have a net on or about 7122 on Thursday mornings to 8:30.  7122 has become a Four State hangout and we have many QSOs there.
 
I have heard of the Sunrise net and hear it going most mornings, but I hear it on 7123, and with some big signals.

Usually stations in SFL are very strong here. I could barely hear

Austin TX. No noise showing up on the S meter either.

I did finally get checked in via QSP with a station in
VA. Interesting propagation.

So not a surprise that a QRP net would have difficulty.

Re: MODERATOR NOTE: Respect for Copyright and Distribution Notices

Hi Tim, 

Thanks for posting this note. Here is a cautionary tale to illustrate your point about copyright. 

A few years ago I was producing QRSS beacon kits with Hans G0UPL. Those of you who attended FDIM when Hans gave a talk may well have bought one. However another ham made a couple of small modifications to the kit and passed on the design to another kit manufacturer as his own to sell. His PCB design was virtually identical to ours including mistakes. 

The amount of ill feeling this caused was incredible and there was no doubt that we lost sales. We considered taking legal action over the breach of copywrite but employing lawyers was too expensive. So there was very little we could do. 

The ham community is generally very honorable and honest but like everything else in life not everyone else plays by the rules.

SMD Parts in a folder

WA0ITP
 

This link was posted on the qrp-tech reflector a weekd ago, and thought Id pass
it along to you in case you didnt see it.

Since I wanted to enhance my supply of smd parts, I ordered one of these 0805
assortments. The price is good, and there are LOTS of parts, both Rs and Cs.

They arrived in a nifty small loose leaf binder with the component carriers
inserted into slots in vinyl pages. Furthermore the order arrived two days
after ordering. There are 3725 total parts averaging one cent each.

For me this is the perfect balance between cost, SMD parts inventgory, and
organization. It adds some class to my junk box :o) Scoll down to see the link.

Gm AJ, Terry And the group.
I have been thunking about this since it was a thread a few months ago.
It kinda went dormant!
It would be great if someone would be the volunteer "club wear" cooridinator.
The company that does the NAQACC stuff has really cool hats, and may have other gear? I think all we need to do is contact the company and settle on a LOGO?
I am good for a Hat or two and a Polo!
OK guys, who is up for the task ?

No one took the ball and ran with it.  This sounds pretty good to me, especially if the company offers hats too.  They would probably sell better than anything else.  Golf/Polo style shirts with collars would also be desireable.
 
If you'd like AJ,  check them out as to products, prices, how to pay, etc and get back to us.  I'd be in for a coupla polo syle shirts, hats, and T shirts.  We'd look good in a group picture at OzarkCon or Brutus.   Thanks much.
 
Anyone else have a source of club related "hamwear"  (izzat a word?)  Bart, how about Pyramid Graphics in Pittsburg?

I love the "QRPometer" that I just finished up about a week ago.

I really don't "need" anything else right now, but I enjoyed the QRPometer assembly so much, I'm thinking I just might have to do something else soon. The Cyclone 40 looks like it might be a fun one to build . . .

Tnx,

You deserve the exposure ;)

I am slowly migrating to QRP. I have just acquired a FLEX-1500 and a LDG Z-11-Pro-II auto tuner. Not quite the real QRP spirit, but I want to operate mostly in low-power digital mode a lot, hence the FLEX.

I'm particularly tempted by K8IQY�s "Magic Box" because I plan to eventually operate with a separate SDR receiver - the QS1R - and it�s dedicated receive-only antenna to pluck weak signals out of the mayhem on some HF bands ;)

Will order �The Magic Box" when I can�t do without it anymore! That could be soon . . .

Hello Jim and Terry,

Thanks for your quick and competent replay. So I will go this way and have a reason to get some solder smoking and putting the magic box together. I have understood the mechanism and will look at the schematics of the Ultimate 3. There is one line coming from the Atmel which triggers the pa. Perhaps I can use this signal. Have to ask Hans.

I have troubles getting into my Yahoo groups since several weeks. Even if I want to reset my password, they will not accept a password of any kind. So could you please send the schematic via email? Thanks for your kindness

And all the Best

Hajo
