2014 Fall Update…

November 1, 2014

Well, we had our first flakes of white stuff today, so guess summer is actually over. I spent most of the summer hiking and walking the many trails around our home town, but doubt I will be doing a lot of that for the next few months. The wifey has told me that we are staying put this winter as the weather forecast for most of the areas that we thought about going to during the colder months are not going to be much better. To be wet and cold is worse than snowy and cold in my book. When your in a 30 foot RV and can’t get out to do things, well it is better to stay home and play with all the toys!

I know I want to play with a lot of Arduino projects this winter and my spectrum analyzer I got at Dayton this last spring, so that should keep me busy for awhile. Still have a lot of kits to build and some homebrew ideas to work on, so won’t be bored. I have even thought about doing some antenna experiments.

I would really like to increase my operating time on CW this winter. I keep saying that every year but never quite get around to it. To be retired and not have the time to do things…go figure. But who knows, I might just do it this winter season. Have a few more winterizing chores to complete and then settle in for a few months of white “bear and grin it” weather…<smile>.

Todd, VE7BPO, has started a blog that looks to be excellent and a outstanding replacement for his web site that he had to terminate this fall. To see his new blog, go to http://qrp-popcorn.blogspot.ca/ and see what he is already posted.  He just conclude a three part series on a receiver called the “Funster”. Leave it to Todd to add excitement to a new project!

QRPHB Web Site Development

October 5, 2014

Todd, VE7BPO, who runs the “Pop Korn” site for homebrewers may have to discontinue the QRPHB web site (http://www.qrp.pops.net/) all together. He and the web master have been having bandwidth problems and it looks like the issues may continue for the foreseeable future. Throughput has been really bad the last few days, and today the site server simply froze up due to a lot of download requests.  At present, Todd has taken the site off-line and will probably not bring it back up. Stay tuned for further developments.

My personal thanks to Todd for all these years of service and sharing with the homebrew community. On the plus side, he will have more time to devote to experiments and testing/measurements that would normally be spent on web site updates. I came across Todd’s work and site back in the late 90’s and have been a fan ever since. He and his site will be missed!

KX1 Building Woes

March 2, 2013

Well, got up to the first Check and Alignment Section and then ran into a problem.The LED display does not work. I suspect U1 which is the microcontroller chip that controls practically everything on the PCB. Taking a break from the whole project and will get back to it in a few days. I have troubleshoot it for several days now and can’t find anything wrong. I can’t vouch for U1 without replacing it…so will have to order it and see if that fixes it.

Stay tuned…

New Project on the Workbench

February 26, 2013

I bought a KX1 back in 2004 while at Dayton and decided it was time to build it. I had forgot how much I enjoyed building Elecraft kits! I was missing a plastic screw and sent an e-mail to them yesterday…that was Sunday. They answered it today and sent out a new screw today…Monday. You can’t ask for better customer support than that.

Here are a few pictures of the build so far…as you can see, I am just now getting started.

CC-20 Build Completed

September 27, 2011

Finished the build on the beta CC-20 tonight. Have a tad over 2.5 watts…but want to look at output on SA and then listen to the tone on the FT-2000. Had a couple of issues along the way…but overall, enjoyed the build despite the dislike of SMDs. The CC-20 was built using 0805 sized parts and found that I could handle them comfortable. Did discover that SMD pinouts of BJTs and FETs are not the same as thru-hole parts…and that slowed me up some.

I still need to figure out why the PFR-3 died when I put it in its case. I have power getting to it…but no audio, and yet have to check transmit. Rain is in the forecast till Thursday, so guess I will start on that tomorrow once I decide how I want to case the CC-20.

CC-40 Update

August 30, 2011

Wow…the end of August is tomorrow, how time flies when your fat, dumb and lazy…LOL. Trying to figure out how to put all these smt (or is it smd) parts into egg cartons and not mess it up. Jason has bagged them in the order in which they are shown on the inventory…but pre-installed parts are not noted and I was wondering why I was missing so many parts.

Dave, AA7EE (another beta builder) has taken off like a rocket and built a lot of his CC-40 already. I’m tempted to wait on building mine until he finds all the snags (only a couple that I know of)…but beta builders are supposed to help out doing this as a team.

Anyway, I think my approach will be to keep the parts in the packaging until I need them…then use egg cartons when there are more than one of each type. I would like to have my built before we go camping next week, but not sure if that will happen or not. I may be going back to work when I return from camping (that is a story in itself), so may not have a lot of time on hand after this week.

I need to update my web page…but that will probably happen after my camping as well. Not much else to say…keep those irons hot and solder fumes floating!!!

Summer Update

August 19, 2011

Started building the PFR-3 from Hendrick’s Kits. Looks like it is going to be a fun build and great radio to use!

Awesome weather here at the home QTH has caused us to hang out here vice traveling around and spending $4.00 a gallon for diesel. With weather like this, I don’t need to travel somewhere else to enjoy it…LOL.

Found I have a stash of TL082’s…so thinking about playing around with some AF filters for a DC receiver or one that I already have on-hand. Using the PRG-80 receiver that Mike, KO4WX wrote about some time back.

That’s it for now. Drop me a line if you have any good ideas for a HB project!

Summer is Here

June 8, 2011

Went from cold, to a few days of warm and now it is just hot! What happened to spring???

Finished a kit from 4 States QRP, SS-40, a 40 meter VXO receiver with a 30Khz tuning range. Really great kit and enjoyed building it. Jim, K8IQY, is the designer and did his usual superb job! Listening to it right now, and it sounds great.

Need to finish the Reggie II kit I bought from QRP-Me a year ago.

Saw some really neat antenna ideas this year at the KOA in Dayton using just wire and the 33 foot fiberglass extending pole. This will be somewhat of a hot project as I can use it on our RV.

Near 1am, so need to get some sleep.

Still Cold…

March 24, 2011

Well the snow melted, but only 24 degrees at present…

Building a Reggie II from QRPme…but already found some mods to do to improve the performance. Never did a kit like this one before so it is fun to play around with it.

Can’t wait to finally start RV’ing this season and just move south as the temps drop next fall. Not sure what to take for HB’ing, but will figure that out this summer!
