Dave..
I should have mentioned that other than KSFO (560 kHz) in S.F. the
local south bay news station back in the earlier days was..
Do you remember what it was?
KXRX was the south bay news radio station. Yes, I realize that it's
not even in the state of Calif. these days. Nor does it have any
history on its Web site. To be able to rack up some free flight time,
my father flew the Peeper-in-the-Piper back in those days with the
late Bob Hallman of KNTV Channel 11 weather giving traffic reports as
my father flew. Later, Bob got his own license and started flying and
reporting on his own. After referencing KNTV history on Wikipedia, I'm
amazed to see no mention of Bob on KNTV alumni. I wonder if those
records are just lost or the company just doesn't keep historical
personnel files. With the transition of owners, I'll bet many a record
is either discarded or lost.
This was about the time my father was flying - perhaps a year or so
befo

Notice ALL the open space at then San Jose Airport - this was _before_
it became San Jose Municipal Airport.

| Greetings Dave..
|
| I did mention many years ago now.. To qualify that, how about back
in
| the 60's & 70's. I see that stations and licenses have moved all
| around the place. Back in those days KNTV wasn't affiliated with
| anyone since they were an independent station. Consider,
| (
http://en.wikipedia.org/wiki/KNTV). Heck, I remember when KLIV 1590
| (as I recall) in San Jose was playing top 40 rock and roll music -
NOT
| exclusively news at all. In fact, I was one of those 15th callers
| after hearing a certain song that won me a Coke jacket as I
remember.
| Too many years ago now but I AM curious how many San Jose folks
would
| ever remember KLIV playing top 40 - probably not many these days..
|
| Those small two-element antennas mounted under the larger TV log are
| still on MANY roofs in San Jose. Granted, probably not in the best
of
| shape but they're there! The twin lead would come from the larger
log
| down to the two-element Yagi, connect to it before going to the TV
| inside the house. After all the complaints of bad video, KNTV did
| something about it by offering these antennas - it DID work well!
| Further, it was a inexpensive solution. They sold them like hotcakes
| back in those days..
|
| Regarding:
| "I need to go up on the roof, and either re-aim the Yagi, or just
| jumper out the combiner and use the northwards-pointing log-periodic
| for all channels - the beamwidth is probably plenty sufficient."
|
| You should try (at least initially) to re-aim it and see if that
| resolves the issue. My bet, it will then work like a charm!! The
| beam-width on a two-element array is broad as a barn! In fact, if
you
| were to only move it an inch or so right now, it would probably
clear
| up considerably. You're probably picking up multipath off of Loma.
| Move away from that reflection point, and things will clear up
| substantially if not totally. My bet will be totally clear video.
|
| Ah, the things we do to avoid purchasing an inexpensive TV antenna
| rotator..

| Mr. Mentor

||
|| Doesn't work worth beans nowadays, since the Yagi towards Loma
