Subject: Beware of RADIOKIT kits (IMHO)
To: ham-homebrew@ucsd.edu
I purchased 2 kits from RADIOKIT (New Hampshire) recently (the QRP-20
by K1BQT and the 7MHz Optimized by W7EL).
First, the 7MHz kit was missing SEVEN parts (5 caps, 1 pot, 1 resistor). After
2 attempts to get these components replaced over 2 weeks, I received
ONLY the pot. No explanation as to where the rest of the parts are.
Now for the UGLY one...... the QRP-20 kit is a mess.....missing parts,
wrong-sized standoffs for critical transistor heat sink installation,
directions furnished are for the QRP 15 (!) with several "mod sheets",
undrilled PCB connections, PCB layout errors, gross assumptions in
directions, changes in kit that were not forwarded to customers, etc.
and etc. And gee, all this fun for $100. "Easy to build ....comes with
detailed manual and parts diagram [for a different RIG]..... easy to
wind coils with _full_pictorials_ [NOT] ...." etc. etc.
This is reckless merchandising at best. I'm no rocket scientist,
but this is NOT what it was portrayed to be.

That is unfortunate. Radiokit has been around for quite a few years;
surely they wouldn't have lasted that long if that kind of performance
were the norm.

Oh, I don't know, maybe they hired a MBA to run their quality control?

Howdy,
I am a new ham, waiting for my license. While I wait patiently for those
12 weeks to pass I figured I would start building some things. One
thing I would like to build is a CW practice oscillator.
Do you have any simple instrctions and parts list for such a job, or
do you know of any place that sells such kits?
I really would appreciate any info you could supply.
Thanks,
Rod

First of all, congrats on the new ticket. The standard simple
code-practice oscillator these days uses a 555 chip and a couple of
resistors and capacitors. You could pick up all the parts you need
(except key?) at any Radio Shack, and I'd bet they have the circuit in
one of their few books. If you key the power to the chip you'll get a
slight chirp at the beginning of each tone, which drives me nuts. You
might want to just switch on the oscillator and key the speaker lead.
If you're looking for more stuff to build, find a store that carrys ARRL
books. They have a number of books with lots of design and construction
info. They also have some files available listing parts sources. Don't
have the info handy, but I could dig it up.
Have fun,
Mike, KK6GM

Try a tv or vcr tuner. They can be tuned with a 4-30 volt source and
some can cover up to 310 Mhz or more. The if freq is dependant on
the unit so you will have to find a receiver that tunes to its if.

To: ham-homebrew@ucsd.edu
Will a coat of paint degrade the performance of a 1.2Ghz antenna? I have a
loop yagi from Downeast Microwave that I'd like to spray with some
"camouflage" paint. Any info is appreciated.
Thanks,
