DX-ZONE ???

Phil Anderson
 


Hey fellow 4SQRPers, how are you-all?

 

Hey, was browsing the net this afternoon and ran across a site with URL www.morse.fusion.com. It's about learning the code while reading mostly words from a novel but some code words interspurced, interesting idea. I was going to order the program to play but could not find a name or callsign associated with the site.....only a link to DX Zone.....  Then I realized that neither site had a ABOUT US tab, saying who they were or where they are located. So I didn't order; guess I'm old fashioned?

 

So, does anybody know about the DXzone or folks who wrote morse.fusion?

I am very interested in getting one of these interfaces and I would like to know if anyone gets one working with the iPad for psk31. I will keep watching here in the group to see what kind of screen devices you guys get it to work with.
Tnx 72/3

The Time Nuts group has also been mentioned on "Chat with the Designers" (CWTD), which has a nice project underway to develop a precision Arduino clock for amateur radio use.

If anyone is interested, the CWTD Yahoo Group is at:

Well, they are low power and we QRPers use time!

GM Pat,

Glad you liked the build, it is a cool kit isnt it.

The small feet are as mistake of mine, and they're not needed. I originally
bought them before discovering that they wouldn't provide clearance for the bolt
heads. Rather than spend the time removing them (time was vy tight) the larger
ones were just added to the kit. Not all the kits have both sets.

Pse let us know how you use the interface and how it performs for you.

Have fun...

Haven't got mine yet, but from what Jerry told me in an email the big ones are supposed to be the ones used.  Shipping of some of the kits (mine included) was delayed until the big feet arrived as the small ones wouldn't fit right or something.

4S-Link kit received

Jerry AA6KI <jpalsson@...>
 

I received my 4S-Link kit yesterday, and look forward to the build. I want to thank Jerry Gorrell, W0CLR, for the very nice job of kitting. All parts were present and accounted for.

Thanks too to 4SQRP for making the kit available.

Re: COIL CALCULATOR PROGRAM

Phil Anderson
 

Thanks Cliff. I too have a coil calculator on my www.midnightscience.com page along with others. Click on formulas or coils on the left hand side of the main page.

 

The key on air core coils for max-Q is that one wants to make the diameter of the coil about the same as the length of the coil. It is also imporant (for max Q) to wind the coil with a gap between turns due to the "proximity" effect. Further, one should use Litz wire if going for Q values above 200 to 300; this is most important for xtal sets (due to the "skin effect" in wires at HF. 72, Uncle Phil, W0XI, Lawrence, KS.

RFTB Sunday night

Larry Makoski <w2lj@...>
 

It's going to be the 3rd Sunday in April!

So join us for that friendly lil' ol' QRP Sprint sponsored by your friends at the Flying Pigs QRP Amateur Radio Club International. Join us for a spell to have some fun and to say "Hi" to friends, old and new.

The time is the same as always:

East coast - 9:00 to 11:00 PM local time
Midwest - 8:00 to 10:00 PM local time
Rockies - 7:00 to 9:00 PM local time
West coast - 6:00 to 8:00 PM local time

The rules are at:

http://fpqrp.org/pigrun/

And to all Flying Pig members, this is a great opportunity to work a bunch of your fellow piggies and then enter your contacts into the WAP log.

Keep in mind to keep checking 7.030.7 MHz for those who are operating crystal controlled Pig Rigs.

Actually, the knob skirt, so I was told, was to keep the ops fingers

could be a problem in the old days.

My straight keys vary with / without the knob skirt, so I just hold the
knob and let the skirt be decorative!
The first key I started with has a skirt, and i found it useful to place my thumb and ring finger on it when sending. But it's the only key I've got that has a skirt. On the skirtless knobs I just hold my thumb and ring finger on the side of the knob.

HY-PER-MITE parts question

Nick-WA5BDU
 

I picked up a HY-PER-MITE filter kit at OzarkCon and am getting ready to put it together. Checking out the configuration options first.

The instructions for the center frequency say to use R1 = 36k for the 640 Hz option (versus 33k for the 700 Hz standard center).

The assembly instructions for setting gain say that for a gain of 0 dB, R1 = 1M.

How do I reconcile the two for 640 Hz and 0 dB? Could one of these be referring to something other than R1?

SMK-2 kit

Is there a forum for this rig? I built one sum time ago. I had sold it, but decided to build another one. This one has a problem with weak sigs to the headphones even with sig generator. The first one would blow your ears off. The LM386 amp is working. Seems like the sig from the mixer is week. Any ideas? 72 George/W2BPI

hey I operate 40 mostly around 7050 or 7042  20 14.050 14.060 14.040 80 3560 3550 then 30 10.116 is working out good. just need a 30 meter qrp set up for 30.. and 21050 the antenna loads 15 now! Hooray.. not much there b/c of band but I look into it.
I operate the upper 40 often too.  so hope fix the tuner or replace it until I can.. I hear plenty of good 5 w sigs and below.. will rejoin u with r4020 soon..
may peddle it for 3 band sold on ten tec sight same price as I paid last spring for dual band..sigh..
think its 80 40 20..well no much 80 until fall.. but i'll sure use 40 and 20 enjoy it now I got the coax fixed on the g5rv.. not as good as a 3 l beam but it works:)  plus no rotor cables controls to go bad. no tower to worry about when storms come.. just a pipe for inverted vee.
one home were looking has no trees. so pipe will work..
