I recently received a couple of excellent photos of completed Willamette transceivers, and I just can’t help but brag on these wonderful creations. W8BH completed his rig quite a while ago but recently upgraded it by adding a KD1JV digital dial. Looks very sharp, Bruce! I’m really getting a kick out of this one. K3PG,… Read More More Willamette Pix
I’m very pleased to report the first (to my knowledge) completed Willamette transceiver which was born in Europe. Vincenzo, IZ5GVP sent along to me a couple of photos of his very nicely constructed Willamette. He reports that it works well and that he’s considering modifying it to operate on the 30 meter band. Three cheers… Read More Willamette Goes To Europe
Thanks to some prompting from a Willamette builder who inquired about some performance issues with his rig, I was able to identify an error in the bill of materials which causes a significant degradation in receiver sensitivity. Fortunately the fix for this problem is very simple. Audio preamplifier collector resistor R49 was incorrectly called out… Read More Important Willamette Update
As I mentioned in a previous post, I did the calculations to change the AF filter in the Willamette from a low-pass filter with a 3.3 kHz cutoff to a peaked low-pass filter with a cutoff frequency nearer to 1 kHz. I finally got around to implementing the mod last night and got a chance… Read More Willamette AF Filter Mod
I know that the blog updates have been a bit light over the last week or so. Although we have been in our new house for three weeks now, it seems like the chores just keep piling up. However, I have done a little bit of work in the homebrewing department. Inspired by messages from… Read More Back to Basics
This weekend, two of the first wave of Willamette builders posted some photos of their completed rigs to the qrp-l.org mailing list. I present to you some of these great pictures with the permission of the builders. First up is the excellent work of Chris Howard, W0EP. Chris placed his finshed rig in a very… Read More Some Beautiful Builds
A few different things have conspired to bring me back around to finish up the documentation for the Willamette, as well as forcing me to re-examine a few elements of the rig design. One of those things was an e-mail from AA0ZZ (really cool to hear from the designer of the PIC-EL and the IQPro)… Read More Another Look at the Willamette AF Filter
Pardon me while I take a moment to direct your attention to the website of KC5WA, who has been simultaneously working on builds of both my Tualatin and Willamette transceivers. RC does an excellent and really thorough job in documenting his work on his projects, and his web pages are a great resource for those… Read More Another Willamette in the Wild
I just got my Summer copy of the QRP Quarterly and got a nice little surprise in the 2008 FDIM Building Competetion and Show & Tell article on page 32. Right down at the bottom-center of the page is a photo of the W8BH entry, his homebrew Willamette rig! Bruce did an incredible job with… Read More Willamette QRP Rig Spotted in the Wild
