Date   

G-QRP Club On-Line Convention 5-6 September

Graham G3MFJ
 

From Steve Hartley - chairman of the G-QRP Club

Folks
 
I am just out of this week's progress meeting for the Convention and all is on track for it to be a great weekend of live QRP talks with Q&A sessions after each one. We have been able to secure speakers to cover the top 10 topics that were suggested in the survey we carried out including construction, antennas, digital modes, propagation test equipment, portable operations and more.
 
The ticket sales have been steady through the week and we have now sold over half of the seats available. If you have not yet booked, I would encourage you to do so in order to make sure you do not miss out; the Eventbrite system works really well but if you get stuck, please do not hesitate to get in touch.
 
The full programme is on the Club website, along with details on how to book tickets and some FAQs about the event: http://www.gqrp.com/convention.htm

Subject: [4SQRP] FS: Bayou Jumper (unbuilt)
 
Cleaning up the ham shack a bit and, after looking at all the rigs I have to work on, decided to put my Bayou Jumper up for sale. Never built - I believe I got it at the 2107 Convention and just have never had the time to build it.  It is an early model (white panel) I believe and I am pretty sure it is all there. No case, of course. Does include a printed copy of the manual, etc. 

Thinking $65 with postage included (US addresses only).  PayPal would be preferred but a personal check or even (gasp!!) cash.  No problemo.  Just drop me a line if you are interested or just have some questions.

Nice to know about the 7100-7125 segment. Kind of where I will wind up when I get back on.  Someday.

interested in CW would most likely enjoy this part of 40 meters when
first getting started with CW.

Johnny,

A nice thing about the Hilltopper is you don't have to go through a bunch of menus to use this radio.  You need to push a button to hear the audio frequency read out, change tuning steps, or change RIT for example, but these are not constantly used functions and there are not many of them to activate.  It's a simple to use radio putting out an honest 5 watts.  (You don't need to memorize or have a cheat sheet handy to be able to use this radio.)  Not a lot of frills but a great basic transceiver doing the basic things a transceiver needs to do and it does it very well.  The parts population is not super close either making construction much easier too.  The more you get to know this transceiver, the more you realize how nice it really is.

Lee-

Thanks for your post, and nice to see the Hilltopper offered once more!  Glad to hear that the top cover is now 'generic'.

I used my Hilltopper-40 for the recent Skeeter Hunt event to the tune of 11 contacts.  Most of those were in the first 20 minutes of operation. Perhaps the most interesting of those was with AF3Z-Jim in PA.  He was running 0.5W crystal-controlled, and was apparently operating from the grandkids' treehouse in their backyard.

Hi Gang,

About two weeks ago Gloria (WD5CMA) and I had a chance to spend a week at our son (W5WWX) and daughter-in-law's cabin the the north Georgia mountains (Blue Ridge GA) inside the Chatahoochee National Forest. Great spot for "luxury" POTA, with mains power,  A/C, comfy furnishings, kitchen, cable TV, WiFi, hot tub, etc. Rough duty, but somebody's got to get those Parks On The Air  :^))

Antennas were held up by a Jackite pole strapped to the deck railing. The deck at that spot is 17' above ground level, so for 20m it was a full size dipole suspended vertically, on 40m it was a slight sloper. Rig, for most of the time, was the K2-QRP running off a 7 aH AGM battery that was topped up periodically with a 600 mA solar panel. Had short-lived mini-pileups most days on both CW and SSB after spotting on the POTA site.

But for a brief 90 minute spell, I threw caution to winds and broke out the 20m Spy Radio, based on Dave Benson's Green Mountain 20, but packaged to look like the Bayou Jumper. A photo is attached. Output is about 1.5 to 2.0 W depending on battery health. Here the battery was three 18650 Li-ion cells in series.

I dived right into the roiling fray of the NA Sprint on 20m, and in that 90 minute span, with a couple of snack breaks thrown in, made 25 Qs, working all but three or four of the stations I called. It was a barrel of fun. So nice to be in an RF quiet environment. So quiet I could hear some slight noise from my Samlex switching 20A supply when I broke it out for a few minutes the next day. Never heard any amid the RF soup at the home QTH in Baton Rouge.

But probably the neatest part was introducing our grand daughter, Tessa, to ham radio. Not quite 3 years old yet, she was fascinated with the straight key and keyer, and we even managed a few words of chat back to grandma on 2m when we were out walking the trails on our "bear hunts". Couple of photos attached as well. All-in-all a wonderful getaway.

Blatant advertisement - they do list the cabin on airbnb - There's no permanent antenna installed, but a fishing pole, some wire and string is all that's needed. I shan't post a link here - that would be too blatant - but contact me privately if you wish.

You could easily unsolder Q3 and test it with your DVM on diode test.  I bought 5 minimodule LM386 amps for $10 delivered.  No constuction just hook them up.

I'm working on adding that $2 amp.  Darn single sided board with too-small pads is a pain to build.  However, I don't think the amp will solve this rig's problem.  I suspect Q3 is kaput.

Thanks.  I'll turn it back around again.  I assume the measurement of Can on Q3 in the Assembly Manual is incorrect.  That's what threw me off.
