Since we have stopped watching football on Sunday afternoon.  What oh what can a ham do. What is the strangest thing you ever built a Qrp rig in.  Rig defined as either a transmitter, receiver or transceiver. Let’s say we will also allow it to be a keyer or antenna tuner. 

Now we desire our device to be something incredible, unique right out of this world. You know something we can talk about on our Qso between now and Christmas.  Perhaps a little bear with a pair of red led eyes. Or rocket ship going to Mars.  Or garden solar light that also becomes our power source. Or the old soup can in the trash can.

Where can we find such an enclosure?  Why in the kid’s junk box, antique store down the road, or perhaps at the dollar store or goodwill.  Now we want it small so we can post its picture on the web. Perhaps limit the size to equal or be less than 6 inches square.  We already know Qrp fans are cheap so we don’t want to spend very much money.  Who can prove they are the cheapest guy in the group.

Maximum ten dollars seems like a lot. Yes it has to be QRP.  Don/t cheat.

So here is the challenge -- small, unique, must work, cost pennies and be something to brag about on our next Qso, or at next club meetings or around the coffee pot tomorrow at work. And were proud to post a picture of our fabulous creative design for others to be a shamed they didn't attempt the challenge.

SO go to the starting line, the pistol goes bang and we are all off running. Smiley It has to be finished before Saint Nick climbs down your antenna mast.

1) How do I know if i'm over driving my TX? Is it simply an ALC thing like on PSK31? I was operating using 50-60 watts today and absolutely no ALC showing. Can I assume that my signal was clean?

2) Is there a cut off point at the start of your TX slot to where your transmission won't be able to be copied? Several times today I was late pulling the trigger calling a station. I didn't start my call until around :05 or so and it seemed like I always had to send a repeat even though my message finished before my :15 sec were up. Is there a point where I should just wait until my next TX slot?

ah, I see.  So maybe a 2 meter transverter is what you need?  Maybe something from Down East Microwave, SSB Electronic, Elecraft, or Kuhne Electronic.  Those usually work with your HF radio tuned to 10 meters as the IF.  Because of the 2 MHz range of the 10 meter IF, the transverters usually cover the lower 2 MHz of 2 meters, ie 144-146 MHz, which is fine because SSB and CW operation is usually in the 144.0-144.3 MHz area.  And if you want to listen to some SSB ham satellites, the downlinks of many those are around 145.8-146.0 MHz

Your original point is probably correct.  I think there are no SSB+CW radios made now that are only for the 2 meter band, so the transverter route seems to be your only option if you don`t want other bands (especially HF) included.  Meanwhile, Icom has shown a prototype of the IC-9700 VHF-UHF radio at the Tokyo Ham Fair a month or so ago, that will have coverage of 2 meters, 70 cm, and 23 cm (ie 144, 430, and 1240 MHz bands), but there is no date yet released for when that radio would become available for sale.  It looks just like the IC-7300 but for the higher bands.

At this time I am using the 7300 or a ftdx3K, they both have some excellent features, if I want a BIG display I put the 3000 in line with its IF out to an external sdr and it gives displays as good as any friends Flex 6300. On the higher bands I like to use the 7300, the NB is the best I have used thus far along with the NR which makes copy like FM, the rx is slightly hotter at times but on both radio's I don't use any pre amps except on 15,10 and 6 on the 3K when needed but both have excellent sensitivity. Do I want a 7610 well after looking at the under the hood pics of the RX board on the 7610 and 7300 from what I have seen its very close to whats used in the 7300 just double. I only wish that Icom would have installed some for of monitor output on the 7300 but its own display may be small but works very well. At this time the 7610 would have to be allot lower in price then the pre TBA has been so far to make me move in that direction.

Eric, please read what you just posted and then read it again.  Tomorrow I'm going to go down every paragraph you wrote and read it and then read it again.  By then I hope to have made some sense of your post and can have some sort of response to it.  Please think before you speak Eric.

Interesting.  ARRL's Letter of 10/19 says that the "Force of 50" (actually 22) has headed home to the mainland as they've been replaced by 10 paid Federal employees who happen to be amateurs.  I'm a tad puzzled.  SHARES is an HF network, coordinated by MARS members (or, it used to be) and MARS members aren't paid federal employees.  But, what do I know.....  Things may have changed.

So, all of the local coordination provided by ARRL's group, largely on VHF and UHF, will be replaced with less than half as many HF-only operators using government equipment on government frequencies?  Good luck.  While I guess the SHARES folks will use a STANAG protocol (and other than SCS Pactor modems to pass written traffic), it seems puzzling that if the needs still exist for regional assistance, another call was not put out for volunteers to rotate those who had been assigned there via the Red Cross instead of a sparse SHARES group.

From the jest of ARRL's writing, a great need still exists.  Not sure that 10 SHARES people can do much of what the 22 volunteers did.  After all, things like trying to contact someone in the states on a federal-only frequency might be a tad more difficult.  Especially since one story of MARS not working well in the Hurricane aftermath and needing amateur assistance to make a contact to summon aid.

ARRL ought to send a second group as there's still lots to be done......

My latest batch of QSLs from UA4WHX arrived in the mail today.

I waited quite a while for these, but as per usual, they do eventually arrive.
