Re: [Elecraft] OT: Warm climate for a vacation/DX holiday

2015-01-04 Thread Sandy Blaize
I have been to St. Croix years ago on business at the petroleum terminal 
on the South side of the island.  Had some time to kill and enjoyed it 
immensely.  Scuba/snorkeling tours were fun and beautiful.  Prices 
reasonable.  Good place for a expedition setup with a QRP rig and a 
Buddipole for some radio fun.  (I didn't have a Buddipole or a small 
compact QRP rig at the time.  That was about 25 years ago.)  Also was in 
Jamaica, Antigua, the Bahamas, and Cayman islands, and Bonaire on ship 
radio repair jobs.  I'm recently informed that one should stick to 
Western end of Jamaica, and avoid the eastern end of the island.  Never 
had any problem on any of these places or been threatened when I 
followed recommendations of previous visitors.


IF I EVER go to these places again, I'll be sure to get permits to setup 
with something like an FT-897, FT-817, or IC-703 using the Buddipole 
antenna system!


Good luck and have fun!

Hawaii (Big Island) is another great place to go if you know where to go.  East Hawaii is much less touristy than the Kona side.

Plenty of guest houses up in the Volcano rain forest where we used to live and 
also down around the quaint old town of Hilo.

YES  The 75 ohm series are UG-260/U connectors, the 50 ohm series is 
the UG-88/U.  If they don't have this stamped into the rear barrel of 
the connector, THEY ARE Counterfeits or JUST PLAIN TRASH!

While you are entirely correct that there are 75 ohm and 50 ohm BNCs, the
difference DOES NOT MATTER at HF, because the connector is such a small
fraction of a wavelength and the difference is small. 75 ohm connectors
were important with analog video because of the smearing of very fine
detail in a high res image, and because studios do lots of patching and
routing.

Re: [Elecraft] BNCs

2014-10-13 Thread Sandy Blaize
The big difference of the 75 and 50 ohm connectors is the fit of the 
connectors to the coax size, NOT the center pin size which is the same.  
BNC connectors are really NOT constant impedance especially at VHF/UHF 
frequencies like proper N series connectors are. This makes no 
difference impedance wise on HF gear.  I guess this is also why no one 
has standardized on a better connector for the HF frequency range

instead of the PL-259/SO-239impedance bumps!

Anyone need 200 silver plated 75 ohm BNCs?

Re: [Elecraft] RM-11708 proposal to FCC threatens CW and digital modes

2014-06-23 Thread Sandy Blaize

 think my comments on RM-11708 went thru.

This is very serious to ANYONE who wants to retain narrow band digital 
communications like JT9 and PSK31 and RTTY!!  Also to CW Dxers and 
contesters!  If this passes, it will change amateur radio as we have 
known it forever.  There will be no weak signal operation possible 
with the onset of digital noise in the analog receiver.


IF THIS IS REALLY A NECESSARY DIGITAL MODE, it belongs somewhere in a 
segment of the phone band sub-band and NOT THE narrow band digital and 
CW band.


I think this is REALLY a back door attempt to silence Continuous 
wave telegraphy..really!


I hope the old timers and the newbies who are still hanging on to CW 
will write comments against this sneaky move ARRL is backing to 
satisfy mostly the Yacht crowd who want to access the internet via HF 
radio!  It will violate the 300 baud or less rule of keeping wideband 
digital OUT of the narrow band digital space!


Don't rely on the FCC to nix this RM as there isn't any real 
engineers at the FCC anymore, just lawyers, bean counters and 
political hacks
running things there now.  Proof of this is higher authorities bypassing 
FCC and making rules that stand now in the new 60 meter band.


Please add your voices to the protest against RM-11708!

There is evidently a short window of opportunity to submit comments to the FCC

If you google for RM-11708 you can read some well-reasoned comments submitted

I can't evaluate the claims being made about ARRL's motivation  but it seems

Re: [Elecraft] O.T.: End of (another) era

2013-07-16 Thread Sandy Blaize
What I am curious about is:  Will they stop the use of AM on the MW 
Broadcast band, the private/commercial VHF and UHF aircraft band, (that is 
picking the primary users of AM) and the amateur bands?  Also will they 
decide that the use of CW will become illegal on the amateur bands, FM 
services to indicate calls signs, the aero NDB's and VORs using CW for ID 
indicators?  To substitute some digital technology for these essential and 
simple equipment technologies just because they are out of date?


Considering the non radio and non engineering political/legal types who are 
taking over as FCC Commissioners, I would bet they want to rub out the 
old systems from ceiling to floor!


Considering the engineering types and the nostalgists and the growing 
interest of newbie amateur telegraphers, I would doubt it!  The iPhone and 
cellphone still hasn't completely erased the CW rag chewer from the 
airwaves.


It would be completely stupid to eliminate the root of radio Continuous 
Wave Telegraphy.  It is slow, but it is simple  and it WORKS.  Why get rid 
of it.

Hi All,

But CW is a conundrum.  It takes skill!  That is what seems to be 
disappearing from ham radio!  Look at the decline in the ability of the 
average ham to build his/her own gear, let alone repair it!  Admittedly, 
the radios we buy these days don't lend themselves to DIY repair, mainly 
due to the advanced technology of things like SMD's, etc.  These days, if 
you have a problem, it usually means swapping out an entire board rather 
than replacing a single part.

This is one reason that I didn't pursue electronics as a career.
Back in the early 70s I was in the Air Force, working on FAA-style air
traffic control radar systems.
One unit that I worked on was tube-based, with probably 100 or more
adjustments to keep it properly aligned (per channel - there were two of
them).
While the most common cause of problems was tube failure, we were
required to troubleshoot and repair to the component level.

Fast forward a couple of years, and we had installed a completely
solid-state/digital auxiliary system.  The only adjustment was the +5V;
not that we ever had to touch that after installation.
If anything failed, we had a flowchart to follow to determine the most
likely *board* that was the problem!  Power down, swap the board, power
up, see if the problem disappeared.
We were specifically prohibited from attempting to repair these boards
in the field.


The absence of a mandatory level of CW proficiency has clearly reduced the 
level of CW activity--except in contests! Interestingly, though, now 
that CW is no longer mandatory, a lot of newer hams (and some old ones 
too) seem to be having some sort of epiphany about the virtues of CW, and 
are voluntarily taking it up.  Very interesting!!!

I'm no psychologist, but it seems that humans respond more favorably to
discovering things on their own, rather than being forced to do so.
Heck, as afar as I'm concerned, anything to further my favorite mode of
communication on the radio.


The bottom line is that technology is apt to change everything! It might 
even substantially wipe away ham radio all together!  It certainly has 
distracted newcomers who now seem to be nearly totally focused on 
computers. I have some serious concerns about the survival of ham radio 
itself, but for now, I think the biggest threat is CC  R's!  Hi.

You got that right!  It's becoming almost impossible to find a new home
without CCRs.
We're planning a final move in the next few years, possibly to
KH6-land.  My two challenges to the realtor:  no CCRs and no HOA.

Re: [Elecraft] OT: Aircraft radio FM

2013-07-16 Thread Sandy Blaize
NO!  I wondered about that for YEARS, even when I was working in avionics! 
The REAL reason for using AM instead of FM is the FM capture effect.  A 
slightly stronger signal on the channel will takeover the channel.  You 
can't hear weaker signals thru it like AM.  This was the real reason for 
sticking with AM for aviation.SAFETY in emergencies or distress 
conditions.


Besides the usual 108-135 or so Mhz for AM aeronautical, the UHF (225-400 
Mhz) the military uses is also still AM.


I think Aeronautical AM will be around for many more years IF some dumb ass 
non engineer decides AM is Obsolete and screws things up.  Seeing the 
present bright political appointees nothing would surprise me!

I suppose the argument about no heterodyne with FM can be
made, BUT ...

AM aircraft radio has been around since the end of spark and
steadily growing world-wide since that time.  It was solidly in
place -long- before FM was a gleam in Armstrong's eye.  It
remains that the staggering cost of conversion to FM is the
real reason it continues today.

Re: [Elecraft] OT: Aircraft radio FM

Yes I read all about RCA screwing Edwin Armstrong on wideband FM.  David 
Sarnoff had connections with the FCC to eliminate the old FM band (pre war) 
and have the 88-108 region allotted  which made all of Armstrong's equipment 
obsolete.  Also RCA claims to have invented a new wideband FM system to 
work around Armstrong's patents.  Armstrong's wife finally managed to 
finally win out over the manufacturer's and RCA in lawsuits long after 
Armstrong jumped out of a hotel window in disgust and near broke from legal 
costs.


I remember FM heralded after the war but nothing ever overcoming the AM 
broadcasters until years later when all the principals were dead by then!  A 
sad story of corporate greed and corruption.  (With the help of the FCC back 
then, a lot of whose engineers got plum jobs with RCA!)

It would have to come from the ICAO through the ITU before the FCC would
consider it.

Digital TV and FM came about because of lobby pressure on The Congress
(money talks).  I can't foresee a lobby for Aeronautical AM.  Very few
technical changes start with staff recommendations.

Re: [Elecraft] QRP and amplifiers for same.

2013-06-18 Thread Sandy Blaize

To ALL,

Agreed, we should have clean signals as there is a plethora of lids who 
are only interested in getting the absolute amount of power out of ANY 
amplifier, be they simple, or super fancy.  Too many GOOD amps are 
overdriven and cause a lot of trouble on the band they are used on, let 
alone the harmonic by products.  Technically the regulations in a round 
about way say an SSB signal should be limited to a 3 Khz bandwidth MAX! 
There are way too many hi fi broadcast lids and such that seem to delight 
in putting their garbage into the next 3 khz channel up or down from the QSO 
they are in!  Politeness seems to have vanished from amateur radio at times! 
NOTHING that the FCC writes into regulations, or forces the manufacturers to 
include in their products will eliminate the common mule headed LID 
operator.


In my humble opinion, the ONLY way to properly tune a SSB linear amplifier 
up correctly, is by the two tone method.  You will get the MOST talk power 
and cleanest signal this way with no guessing.

most do not have any real semblance of ALC making it very easy to overdrive

Re: [Elecraft] why mix rf connector types within the product line?

2013-04-26 Thread Sandy Blaize
Obviously you are not listening.  In the Elecraft line, the QRP rigs ALL use 
the BNC connector.  They work well.  Adapters are available for BNC/binding 
Posts...very practical in a filed installation.  Who wants to be bothered 
with perhaps the poorest connector ever devised for no big impedance bump, 
very poor connector in the VHF UHF range.  (Any sharp repeater technician 
will curse the PL259 and favor the MUCH better N connector in the VHF/UHF 
range!)   Three cheers for throwing the damned RCA phono plug out that was 
so pushed by Collins radio.  They actually are BETTER at VHF than the 
PL-259/SO-239 which should have been made obsolete years ago.


All I can say is Get used to making up the BNC plugs.  They made the best 
choice for QRP stuff over the PL-259/SO-239 and the RCA plugs for RF use.

I don't want to buy or make or use any adapters.

Why not keep the connector consistent across the product line?

That is the question!

In effect now we are forced to need adapters.


Or you could get some thing like:

ssemblies-bnc-n-pl259-sma-so23/pl259-to-bnc-male-jumpers/

I can't vouch for ABR's products (never tried them). Personally, I would
make my own

TOO MUCH, especially on weekends!   Shouldn't there be a small segment of 
the bands set aside for non contest use?  Or would this be asking too 
much??

Re: [Elecraft] Is ham radio a sport ??

2013-03-21 Thread Sandy Blaize
Bill,

AGREED!  Also don’t forget about 60 meters!  A lot of people miss a “good bet” 
to contact some of the people they usually work on 80 or 40 meters when those 
bands are jammed packed on weekends with contesting!  Unfortunately, for the 
most part, you can’t work 60 with old boatanchor gear.  It is even more useful 
now that they have allocated a “new channel 3” instead of the one that always 
seemed in government use.  

Even though there is no contesting on WARC bands, there are times the 
propagation isn’t right for some areas you 
normally work on 80/40/20 meters  (especially 80/40 for short skip stuff).  It 
would be helpful to have a small section of the bands “off limits” for 
contesting on the CW-data and SSB segments of each band in areas that 
General/Tech class people or higher could use during the “tests”.  I queried 
ARRL about it a couple of times.  The ARRL Official Observers could be 
reporting those stations and times that the “violations” occurred.  If you got 
more than say 5 contacts in the “off limits” segments, You could have you 
entire log disqualified.  The “segments could be small, say 10-15 khz max.and 
leave a hole for those needing to work buddies across the continent.  I didn’t 
even get an answer from them about this.

What operating courtesy existed 20+ years ago and the use of calling protocols 
during CW contacts has almost ceased to exist now.  Some of the “no coders” ARE 
trying, so it’s up to us old timers to “educate” them about on the air 
politeness, even if ARRL doesn’t care anymore.  (They no longer put the 
“Operating an Amateur Station” chapter in the “Handbook” anymore!)

Most of the “newbies” I have QSOed are willing to learn, but seem to be 
mimicking the techniques of the “hit and run” techniques used by the hard core 
contesters, most of which has no place in a casual polite  QSO!

Just my 2 cents worth from someone that’s pounded a key since 1951.  All my 
stern “Elmers” are “SK” now I’m afraid.  Sometimes they had stern words for us 
beginners back then.

Sandy, 

Actually, ALL WARC BANDS (30, 17, 12 meters) are already off limits to contest 
activity.  This is strictly enforced by contest organizers by rejecting any 
QSOs submitted for those bands.  Although I am a contester, I don't enter every 
contest.  The WARC bands offer a wide variety of propagation characteristics 
and I really enjoy using them.
