Re: Dummy?

Bill Cromwell
 

Hi Sam,

Better yet - at the back of the shell solder a metal disc (copper is a good bet), over the opening with a small, centered hole for the grounded end of the resistor and solder the resistor lead there. That maintains the impedance straight through the connector/dummy load. This is less important and perhaps completely unimportant at HF, especially from 40 or 30 meters on down through 600 meters and longer. At VHF it becomes very important.

Carbon resistors have been shown unreliable/unstable of over the years. Apparently the metal film resistors are superior in *every* way including non-inductive. If you have the carbon resistor and it is still 50 ohms (or 49 ohms etc) by all means use it. Measure it before and after each use just to be sure it is still doing what you think it is doing. I check such things on all of my gear from time to time to avoid unpleasant surprises.

BNC size connectors don't have a lot of extra room but it is possible to combine several resistors to increase the power handling ability of the dummy load. I have a couple of BNC shell/dummy loads here that will not handle more than a half watt used to terminate signal generators and receiver tests. The one that is in the PL-259 is good for about ten watts.

Hello,

Take a 50 Ohm resistor ( carbon! ) ( 5 Watt if you can find it ) and slide one
end with it's wire into a coax connector, so that the resistor is now hidden
inside the coax connector. Solder the resistor's wire sticking out of the
center pin and cut off the excess. Then, solder the wire on the other end of
the now hidden resistor to the coax connector frame and cut off the excess
wire. You now have an almost free 50 Ohm dummy load. If you can find one, glue
the protective cap that comes on the end of a spool of coax over the open end
of the connector for neatness. The only problem I have with mine is keeping up
with where it is.

I guess I'm the dummy asking this, but I haven't found a simple solution
thru Google, so I thought I would ask the experts directly: what is the
simplest dummy load I can make for my QRP rigs?

TNX in advance...

Hi John,  I had to be out of town Sunday night.  Unfortunately had to miss the sprint.
Thanks for the work you do organizing and tabulating scores.

It's Monday and time to send in your QSO count for the Sprint held last night, if you haven't already.  I'll wait until tomorrow morning to tabulate everything, so get those scores in today before you forget.  Please include you callsign, name, QTH, number of QSO's, and optional soapbox comments.  That will make it easy for my to put it all together.  Thanks.

Banner & Monday Sideband net!

Jeremy Utley
 

Hey all!

So, I had a minor family emergency come up over the weekend. My
father got his thumb caught in the blade of his table saw Thursday
afternoon, and ended up having to have emergency surgery on Friday to
have part of it removed. Because of that, I did not get to complete
publication of the Banner like I had planned this weekend. I will
attempt to get it done later this evening.

Also, I have a meeting for my local CERT team this evening, and
because of that, will not be able to call the Monday sideband net. If
anyone else is willing, go ahead and call it and have a little fun
(Doc, K5OSA, maybe you should try your hand at it! It's easy to do!)

Have a good day, everyone!

Thanks Gang have a great and safe week...

P.s. Had great fun working a few 4SQRP SSS Sprint last night. I sent my results in... 4SQRP... Member 389...

There you will find all the details as to time, frequencies and other important
information.

Certificates: SWA (simple wire antennas) certificates by call area, VE and DX
for 1st, 2nd and 3rd place finishers (New!). A Certificate for top score in the
GAIN antenna category.

Prizes: Too many to list!! - check out the prizes page on our website.

This is a monthly event that caters to the CW veteran, the CW newcomer, straight
key and bug fans. All are welcome to participate (this includes QRO); but you
must use QRP power levels to compete for awards.

If you've been hesitant to join in our sprints because you hear other sprints
running at breakneck speeds, have no fear. Our sprints are geared to the
newcomer to CW and/or contesting. Virtually everyone including the many veteran
contesters who regularly enter our sprints will slow down to YOUR speed to help
you make your contacts.

If you are not already a member of NAQCC... membership is FREE! Now is your
chance to join the largest QRP CW Club in the world!! We currently have 7100+
members in: All 50 States - 9 VE Provinces - 100 Countries. Sign up on the

FYBO2015 Summaries, Soapbox, and Logs

John Stevens (K5JS)
 

A question or two about logs has come up...  You really don't need to send logs if you don't want to.  All that is really necessary is the short scoring summary or something like it with all the info detailed on the FYBO 2015 rules page at http://www.azscqrpions.org.  If you want to send logs, feel free. Anything will do. Email text, adif, cabrillo, whatever.

Please do include a little write-up about your adventures and pictures for the Soapbox section.  OR send a link to them if you have already put them up somewhere.  We'll include your links so we all can enjoy your write-up.

Send your summaries and soapbox stuff to FYBO2015@... or even reply to this email.  It will get here.

Here's a point getting tip!  Remember to use the LOWEST temperature you experience. Send it all day long.  Have that thermometer out at the starting bell and get a cool number.

We are looking forward to Saturday and hope that you will jump in and make some contacts and let us know how you did!!

Tomorrow night is the deadline for putting together a team!  Email k7ddmjb@... with your team name and members!

Watch for several NQ7RP stations on multiple bands at White Tanks mountain park on the western edge of Phoenix.  NQ7RP/5 will operate from the swamps of Louisiana between Baton Rouge and New Orleans.  The Louisiana station will start out on 80M and work up the bands looking for stations.  Yep. That includes 10M later in the morning too.

See you Saturday!  Reply to this email with questions or to K7DD.
