site, enjoyed your history....brought back the good
First call here was KN8VOP, Livonia, Michigan, I think,
the late fifties. Had a DX 40, xtal controlled, and
an Hallicrafters S108 with a Heathkit QMultiplier.
Later became K8VOP but then discovered girls........I
am K9DP now, just an old cw operator.
Thanks for the trip back.

HAM RADIO and HOMEBREWING
Today, in amateur radio much too little HOMEBREWING
The modern integrated surface technology makes it nearly
impossible to do homebrewing of equipments, as the required
laboratory is rarely available to HAMs.
But this is quite different for antennas.
Here, homebrewing should be practiced much more, especially,
as we can obtain far better antennas by own construction
than many of the commercial ones. And at a much, much
lower price !
Good success and best 73s
I am VY glad for your description of the LP filter for
50 MHz. Am VY experienced and proff - but tried to look
up for a suitable filter for the 4CX1500B PA.
I have NOT finished the project, but the filter will be
used for the double 4CX250B stage until finished. It looks
like it suits the 1500W power-level fine.

you for providing this website. I hope to have a Z3801A soon.
The information here is just what someone needs to get it
up and running. I have spent a lot of time browsing this website

C. J. Robinson, K0CJ
for all the info on the Z3801A. It helped me quite a bit in
getting mine up. On the suggestion of another local ham I
connected the serial port directly to my PC with no level
conversion or any other interface between it and the normal
"RS-232" connector on the PC. It works just fine. Any thing
wrong in this?

Thanks for all the great info you're bringing together. I
have a Z3816 that won't sweep to find lock which gives an
EFC-err. I suspect, with all the Z3801 and Z3816 info you're
getting, that the answer will be hiding in there somewhere
once I digest it all. Nice QEX article too. 73.

site! I got so excited I ordered a Z3801A, a 48-volt power
supply from jameco, and the GPScon software. My plans are
to sync my test equipment to the GPS and perhaps find a way
to also drive my kenwood TS-2000. If anyone has looked into
that I'd appreciate an email. 73 - Juan - WA6HTP

to see a REAL Ham Radio site, where REAL hams still build
rather than recite Yaesu, Kenwood & Icom model numbers in
conjunction with their Visa card numbers. HI HI You have a
good start here, keep up the good work. My OM W7YZQ got me
interested in home-brew, and I still like busting my knuckles
with hole punches, etc. designing my own goodies. Gary Hildebrand

Location: warrens, wi USA
thanks for all the help with the Z3801-mine is showing holdover
around 1.6-2 microseconds/24 hours. and measuring timing errors
in the 15 nanosecond or less area. tracking minumum of 6 satellites
and 2 on standby at all times. i would be very interested
in finding a way to put the stats on the internet, so put
me on your mailing list for the new monitoring software. i
have been comparing it with WWVB using a HP-117A receiver-comparator.
i am 730 miles from WWVB, which is in a sky wave-ground wave
interference zone, so summer is a difficult time to compare.
but winter is usually quite stable. will continue working
on that. when the signal from WWVB is good, clean, without
propagation disturbances or thunderstorms, it is very accurate
for frequency comparison. i am using a prescaler divide by
100 chip to bring the 10 MHZ to 100 kHz to do the comparison,
and previous exprience leads me to believe the prescaler is
accurate. using the cone-shaped Motorola antenna designed
for this application, and signal strengths are usually above
100 to 250 or so or even higher. thanks again for all the
