Second Sunday Sprint

Walter - K5EST
 

4State QRP 2nd Sunday Sprints

August 11th ... 7 to 9 PM (cdst)

any mode and band, except WARC & 60 mtrs, no NCS, 5 watts maximum
output regardless of mode. The Sprint keeps the keys, mics, and
keyboards active and collect the valuable QSO contacts that are needed
to achieve the W25 awards.

 <http://www.4sqrp.com/ActivityRecognition.php>

 Suggested calling idea is.....CQ 4S....and obtain the stations 4SQRP
number for W25 awards. Please stop by the 7.122 MHz group hang-out
frequency to allow the crystal bound stations to have fun, also! Also
some folks have not changed their Pig Rig from 7.030.7 MHz.

We have yet to have a SSB or digital entry, there is room for everyone!

Exchange, club member number or None if non-member. You may want to give RST and your club number.

 There is more at stake than the W25 awards, the most QSO contacts
station by October 1st, 2013, wins  the club callsign WQ5RP for the
October 4x4 Sprint. (in case of a tie of QSOs, then we shall draw a
winner). With a massive multiplier attached, this may be the most
coveted contact in your logbook for the 4x4 Sprint!

 Reporting is easy.....send me an email to

spike55@...

Put SPRINT in the subject line then in the text body, indicate your
number of QSO contacts and what mode.

......I will compile the total of entries and post them on the club
yahoo groups reflector!

Brutus Bash

Jim Sheldon
 

As it stands right now, depending on the weather, my wife and I plan on being there for at least Saturday and maybe even Sunday.  
 
For those who haven't seen one, I'll have my Elecraft KX3 there and anyone that wants some hands-on time with one will be able to operate it.  You'll be able to use either the Elecraft paddles that mount on the radio, or I'll have adapters on hand to allow you to plug in your own set of paddles.  I'll have enough battery power available to run the rig the whole weekend and still have some left over so it ought to be fun.  
 
As we don't own any camping gear, we'll be staying in one of the area motels so might actually be down Friday night.  I'll be bringing my portable "gazebo" with some netting and a tarp to provide shade and keep most of the bugs out so it ought to be a really fun weekend.
 
Looking forward to see the big "skyhook" antennas too if the wind doesn't get too wicked.  The KX3 ought to work great on 160 meters with a lot of wire in the air and usually by September the evening band noise is starting to quiet down on 160 as well.

Re: QRP SSB

Had my receiver on scan since we first talked about a group SSB watering hole. The lower SSB freqs of 40 meters (here) seem to be busiest vs the higher end of the band. On or about 7.278 MHz has been the quietest, here!

Hope we can find something soon!

Re: QRP SSB

Curt
 

Dan

often we don't need those extra couple S-units after all (but sometimes we do!)

I use to to more 'QRP' SSB when my K2 only could do 10 watts, just to enjoy its niceness compared to my then larger rig. of course, often it worked fine.

I also sometimes enjoy a state QSO party, and sometimes I infer based upon the path where QRP will work well. Sometimes I can't 'compete' with 100 watts because I am too close to the target state for any 20m QSOs -- but find that QRP SSB works well on 40m (and sometimes even a few on 80m) to add some contacts to what I am getting on CW.

of course, the main motivation for QRP is (a) building stuff and (b) portable operation. the SOTA ops do find SSB is useful in their bag of tricks, and here multi-band capability is a virtue -- so I sense they will be less motivated to use homebrew or 'simple' kit rigs. as those KX3's and even K2's are rather pricey -- one can wonder if there would be a market for a dual-band (20/40m) SSB/CW QRP rig that is easy on the battery and wallet? hard to say, and equally hard to design for 1/2 price (maybe also half the size) of a K2?

well if you arrange your shack so that a CW rig is normally the incumbent, you might do more CW ! my 'homebrew' headset doesn't yet fit my K2, so I do more CW. but during '6m season' I do find myself being more bi-modal.

I did use my 'PTO stack' of Cyclone and NC2030 in a recent QRP contest. One needs to find opportunities to get their nice lesser rigs into the starting lineup. Not much Cyclone traffic - so maybe everyone's build is going smoothly.

Re: QRP SSB

"QRP Syndrome" has been around quite a long time. I first notice it probably around 1979.

One of my favorite QSO
's was a guy bragging about being stuffed from having just finished eating a very fine meal. A couple of go-round's later I mentioned that I was QRP running a Ten Tec. His next transmission was that he had to QRT immediately, since his wife just called him for supper. I didn't get a return QSL from him. Perhaps I should have included a packet of anti-acids with my card ;)

I posed the question s to WHY, and several thought the QRO guys are embarrassed by how much they spent on their equipment. Many surely don't want their wives to know that they have thousands in the Rigs and thousands in the Towers and Antennas, and some guy with a $100 in a little bitty box and a chunk of wire can talk to the same places world wide.....

Re: QRP SSB

Dan Reynolds
 

David, Walter, everybody, thanks.

I like QRP. I love my 817. And I love making DX QRP SSB. I don't think I'm a real DX'er - I just like it when I hear one and wait around and finally make a QSO. I have no dreams of DXCC or anything like that. My biggest goal, 1000 miles per watt, I earned earlier this year. Now, it'a all fun.
Last night I ended up with a UK, a Czech Republic and a Slovenia. 20 meters was hot last night.

I agree on a 4SQRP SSB watering hole. How about 7.222 or 14.222? i know .285 is the "official" on several "lists" but I've yet to hear QRP on there ever.

I'm not giving up on CW. But I'm better with a mic than a key... At least up to this point. But Terry & Johnny are pushing me and I'm going to keep trying. The rigs are sure easier to build! Hi, hi!

Thanks again for the encouragement. And pick up a mic sometime. Hopefully it won't bite you! ;-)

"SELECTIVE QSB" is no joke. 
Several times I had a good QSO going,

"??? QSB ??? 73 " 

Speaking of    QRP-SSB    and    QRP -W, 
maybe there should be designations for SSB-QRP and CW-QRP , 
some special pet name,     just so we can tell which group is speaking.   

Congrats to anybody who makes a very long distance QRP SSB contact !
QRP with SSB is much more difficult than for CW. 
With all that QRP RF spread out over 2.1 KHz bandwidth, 
it is no 'calculated' match for CW.  
QRP with SSB is much more difficult than for CW. 
Congrats to anybody who makes a very long distance QRP SSB contact !

I am not biased in favor of SSB,   I have never operated any phone rig. 
Have always operated CW, way back  in 1958,  and now again in 2013.  
1958,  My ARC-5 did not send AM,    and my '46 BUG did   not listen to my voice. 
2013,  My HW-8 will not send SSB,    and my '46 BUG will not listen to my voice. 


This is a really interesting Radio Operators group.

Re: can't sleep ? talk on the radio...

Glen <glene77is@...>
 

Julio Jimenez, AK4VL, 

My QRP best contact was my first QSO in 50 years. 
On 2013, March 17, 1700 EST, 
on 20M  14.041, Miami, FL, to Memphis, TN, 
between Wy4J  and  KK4LPG,  862 miles. 
Registered on www.QRZ.com,
and confirmed by WY4J on QRZ.com, 
and confirmed by email. 
QSL card received both ways. 

TX was Kenwood TS-830s, with bad driver tube, 
into an MFJ-941 tuner, indicating 1 watt out, 
and SWR of 5:1,  which calculates to 0.2 Watts into the antenna. 
This was Loaded into an old telephone cable running through the house. 
So, my little 0.2 Watt for 862 miles is equivalent to 4310 miles per watt  !   

That contact was done as a "lark", not expecting anything. 
but it was a real thril to this old man.  

I know it is   Just a drop in the QRP bucket, 
and there has been nothing like it since. 

I use a HW-8 now, running just over 1 W,  CW only, 
almost always on 20M, into a Long-Wire, now. 
Most contacts run in the 600 to 900 mile range, 
or 1500 to California, or 1600 to Puerto Rico. 
Between the Vertical and the Long-wire, 
this has been an interesting experience. 

Have a new Rotary Inductor Tuner now, 
and the HW-8 shows twice as much "Relative Power" now, 
but have not been able to measure exactly how much, 
as the metering is different.    

So, do you require a special power output meter for "EPO" 
when documenting a low power contact ?    
Just curious how things go. 

At 1 W the signal is very easily buried in the sky-noise. 
Occasionally there are contacts on 20M, several times a week.  
When the conditions are right, there will be two in a row!
Big rigs will be turning their beams every way but me, 
and their RF gain is down, so there goes my QRP signal. 

I am curious if my QSO has been documented sufficiently and properly  
to qualify for one of your certificates ? 

However all that turns out,  just publishing what info I have is good.  
Like chatting around a table.    Its just for the good times.

Yes Jeremy, a 4sqrp SSB watering hole!  Not sure about getting too close to 7.285 MHz since the AM phone guys hang around there with a  w i d e signal. And 7.275 has a group that is pretty active. Maybe 7.278 ... could do some listening over a few days.

I myself would love this!  Something like 7122 is for the CW guys would be great!  Heck, maybe even a Wednesday night SSB net?  I'd even be willing to try my hand at net control of that one, at least part time!

The NJQRP web site lists 7285 as a recommended QRP calling frequency for US ops, 7090 for EU.  That is up there in the SW area of the band tho.  I haven't listened to what the clear frequencies are, but maybe we could adopt something around that - maybe down 3 (7282) if there's no SW there.  Just a thought - I'm open to just about anything!

I don’t get much time to operate but on 40 meters with five watt ssb have worked CA, UT,  NM, LA, MT, ID, WA, TX, HA, AL, VE7, VE8, Japan and some more that I don’t remember right now.  With less power than a little flashlight and working stations well over a thousand miles for me is exciting.  Have made some good contacts on 20 meters also. 

 

I enjoy operating with 5 watts and solar panels here at the house field day.
