Thanks to all who have contributed to the column. I am preparing two columns
for the next two issues and am anticipating a very insightful guest column
from a well-known European DXer, but also want to get your inputs on another
topic. I'll forward the most promising article for submission this time and
refine the remaining article for the May-June issue.
The topic: Is now the time to homebrew that dream linear or monster antenna
tuner?
There are two words that help answer the question: "Russian parts"!! Just
like the post-WWII era, we're enjoying the "Peace Dividend" resulting from the
end of the Cold War that has produced a windfall of RF components. Russian
parts, including good quality amplifier tubes, vacuum variables, and inductors
are cheap and plentiful on the Internet. Do you have plans to build a new amp?
Do you plan to upgrade a present amp with cheaper and more robust Russian
tubes? Are you looking to buy and modify one of the several amps (such as the
GLA-2500) that can be retrofitted with Russian tubes? Are you planning on
building that monster antenna tuner with vacuum variables and big inductors?
Are
there other parts bargains that you'd like to share with the community?
How you might take advantage of this RF parts windfall? Please provide
inputs by Friday, January 16th.
Thanks in advance and 73,
Paul, K5AF
