The ko4bb.com site will be moving to a new home.
The traffic has slowly but surely increased over the years and our current home is
simply not big enough.
I have been advised that this site could be shut down without notice, so I
have temporarily suspended manual downloads until the new site is up (you will get
a 404 Page not found when trying to download).
Do not be concerned, none of the manuals will be lost in the process (they
have already been transferred to the new site).
However, it would be appreciated if you could delay uploading new material
until the transition is complete, in a week at the most.
For a quick look at how the site has evolved over the last 7 years, check
the Statistics page.
Thank you for your patience.

KO4BB's Ham Radio Pages
- Manuals for Ham Radio, HP, Tek, Fluke and other equipment
- Ham Radio VHF/UHF Beacons (sortable)
- Hardware Projects:
- Software Projects:
- ADIFLookup: A program to automatically add name and address to an ADIF file.
It uses the QRZ.com on-line database, so you need to be connected to the Internet for it to work.
This comes without guaranty of any kind. If it blows up your computer, wipe out the C: drive or anything else,
it's not my fault.
Check the Release Notes.
- QSORecorder: A program to facilitate recording and playback of audio captured
through the sound input of the computer.
- Product Reviews
A list of ham radio related frequently asked questions
- The world as seen from KO4BB (this is the desktop background on my computer :-)
Make a similar map for your QTH using SM3GSJ's software.
- Ham Equipment at KO4BB
- Spectrum plots of a few random stations, when propagation was particularly good.
The plot of AD4TK is different since Jack is my neighbor... It turns out his net on 7.165 MHz LSB is pretty much 1/7th of the calling
frequency on 6m. His powerful, yet clean signal causes severe overload of my 6m receiver (FT-817), worse when the 6m antenna
is pointed at Jack's dipole antenna, about 400 feet away. As shown on the picture, his signal is clean of intermod. Harmonic
on 6m is too low to be measured by the Tek 494 spectrum analyzer (no picture). Good thing the net is only once a week :-)
I think the fix is a high pass filter at the input of my 6m receiver to eliminate the fundamental 7 MHz signal before it
reaches the receiver.
