Which BNC-to-SMA Adapter?

K6LCS <clintbrad4d@...>
 

From my In Box ...

... I have a large antenna with BNC male connector that I did not use because I need to get a adapter for the bnc so it can fit on my SMA radio ...
Please consider either a NCG/Comet HB-05 BNC female to SMA male 18-inch jumper, or the Stephen Gulyas adapter. Either will protect your radio's SMA jack and center pin from stress.

The HB-05 is available from fine ham radio stores nation-wide. Info on the Gulyas adapters available at ...

SO-67 Ops Notes from K8YSE

K6LCS <clintbrad4d@...>
 

From the FM-SATs group ...

Audio for the SO-67 eastern USA pass on 21Nov09
is on my webserver:

http://www.papays.com/SO-67_21Nov2009_143116z.mp3

Now that it is understood that there is a 3 second
tail after each transmission and audio will cut off
after that time has expired, ways to get around the
problem can be devised.

I found that when called by another station, if you start
transmitting before that station releases their transmitter,
you will be able to answer and not be cut off after 3 seconds.
This is because the "tail" never started. However, if this
continuous transmission goes on for 30(?) seconds, the next
timer will shut down the transmitter. Waiting for the tail
to expire, when the bird is over the USA with many stations
trying to get in, will not work. There will always be someone
who keys up during the 3 second tail.

Signals were loud as usual right down to the horizon. The extra
transmitter power will enable many new users to get on this bird.
Thanks to all of those who had a part in launching this satellite!

How to program the FT-51R

James H <jameshickox@...>
 

Hello all,

I am looking for an easy way to program in the FM satellite frequencies into my FT-51R.

My plan is to step throuth the channels as needed to correct for doppler, byt I don't have much experience with this radio yet.

Any help is appreciated.

Thanks and 73,

Re: More Mods to Arrow Satellite Antenna

From the IN Box ...

You can actually slip the duplexer out of the boom and see how long it is. I have about an inch of clearance.

FT-60R a Good Beginner's HT?

K6LCS <clintbrad4d@...>
 

From the In Box from a soon-to-be ham in Mesa, Arizona ...

... thinking about getting the Yaesu FT-60R. What do you think about this radio for a beginner?
It is a GREAT rig - not only for someone new to the hobby, but to anyone in Mesa who wants to communicate on your local repeaters, work the ham satellites, and talk simplex.

You have a couple good clubs in the region ... been to a Superstition Amateur Radio Club meeting? They have 2 meter machines up on the mountain. As well as several other clubs.

Back to the FT-60R. It features ...

- 1,000 memories
- Wide receive (essentially 108mHZ to a gig)
- Large, legible display
- Easy to manually program
- Bulletproof case design
- Strongest belt clip of ANY ham HT chassis on the market
- GREAT battery life - and a great power situation using the optional FBA-25 AA alkaline case: You have FULL TX POWER available to you using AA alkalines or NiMH cells. Many other ham radios do NOT offer high power TX when using their optional AA cases!

I own many handheld ham radios. Most were more expensive than the FT-60R. But you know which radio I have taken and shown its capabilities to ALL of my 50+ ham satellite demos and presentations? The FT-60R.

Please download a copy of my one-page programming instructions from my Web site (don't toss the 84-page Users manual ... just know that you don't need to memorize all that stuff to get on the air quickly with your FT-60R).

The FT-60R is available NEW and WARRANTEED for under $200 from Ham Radio Outlet, Amateur Electronics Supply, and other reputable Yaesu dealers. I recommend NOT looking for a used one ... you have no idea what abuse a used one may have been subjected to ... used ones never come with a NEW battery ... used ones are not, for the most part, guaranteed at all.

PLEASE WRITE BACK with any questions or comments. And congratulations on your interest in this magnificent hobby!

Tape Measure Yagi

PocketSat - RIP ???

K6LCS <clintbrad4d@...>
 

Unfortunately, I heard "one of us" report last week that "PocketSat isn't really popular any more, with the demise of the Palm computing platform ... "

That's woefully incorrect on many fronts.

Palm users are plentiful, and Jim is still supporting us. PocketSat+ is still the best Palm-platform satellite tracking software available, IMHO. Support still at ...

http://www.bigfattail.com

But Jim has not let his programming skills stagnate. We now have PocketSat3 for the Apple iPhone and iPod touch devices. It provides gorgeous screen graphics for our passes. Available in the Apple Store. Docs and support at Jim's new site at ...

http://www.pocketsat.com/

It works marvelously on my new 32GB iPod touch. AMSAT's keps are one of the four default sets for painless download. Recently added is a "View Constellation" mode - which overlays your view of the heavens on a sat pass.

There are several "satellite trackers" in the Apple Store ... from free to $.099 to a few bucks. I have tried five others. NONE of them come close to the feature set, ease of use, and product support that one receives with PocketSat3.

I would assume that "true" North would be correct ... since it is not "variable."

When the coordinates are given for a pass,
is the reference Magnetic North or True North?

FT-817 Programming Software

K6LCS <clintbrad4d@...>
 

On another subject; what is a good and affordable programming software for the FT-817?
I have an older copy (pre-USB cable setup) of RT System's ADMS-4A ...

The current version includes a USB cable:

ADMS-4A-USB - $49
Advanced Data Management System USB Kit
-with Version 4 Software and New USB Cable

Includes: Windows based software for programming the
memories and settings of the FT-817.
For Windows 2000, XP or Vista (32 or 64 bit).

AND

USB-62 - USB to 8-pin mini din cable computer interface cable.


But if you already have a Yaesu CT-62 serial port to the radio cable, you might like this software for $15 ...

I managed to listen in on two passes of AO-51 this afternoon and evening. There were lots of signals and managing the Arrow II in the gusty winds was a bit of a challenge. I didn't change frequency to allow for the doppler shift but the signals were still very readable through most of the passes.

I hate to admit it, but I used programming software to program my '817.

But I *can* manually program split freqs on an FT-60R! (At least I think I remember ...).

Clint,
 
Thanks for your un-scientific analysis of the two antennas which I found very enjoyable to read. I just received my used Arrow II yesterday and got it put together this morning. I'm going to see if I can hear AO-51 this afternoon here in south central Iowa. If successful then on to the daunting task of programming memories into the FT-817ND.
 
I'll keep the group posted with my progress. I'm retiring later this week so should have more time for ham radio and for flying my homebuilt as well.

I have not been able to determine WHEN and WHY that "anti-Arrow" sentiment started.

Some will tell you that you need to add little washers to each Arrow Antenna element. Others state that its duplexer is a miserable performer. Let me tell you a story ...

While I was working at Ham Radio Outlet, a client - an ENGINEER - bought an Arrow Sat Antenna w/duplexer from me - on my recommendation. I mean, I bought one myself, and was enjoying it. I wanted all my clients to enjoy them, too.

But there he was, waiting for me to open up the shop the next morning, Arrow Antenna in hand. "This cannot possibly work," he declared. "It is engineered all wrong. I want to return it."

Part of me wanted to "question / challenge" him and find out what troubled him. But he was so adamant that I immediately dropped that idea. Instead, I began to think, "Open Stock item - 10% discount ... " So I cheerfully refunded him his money, and bought the "defective, engineered all wrong" unit myself as soon as he left the store.

And you know what's coming next: Honest to gawd, it is the exact same antenna I have been using the past five or six years for my demos and presentations. The only "degradation" from Day One has been the color of the elements (brand new out of the bag, they're a vibrant purple. Mine, however, have "faded" over time to what I term an "elegant, well-worn light purple ... "

There WAS an honest, un-biased test result posted recently on the 'Net of the Arrow duplexer used, indicating about a 1/3 of one db loss through it. That is quite reasonable, and what I would expect from that circuitry.

And if one uses one of those little 18" thin jumper cables to convert from the Arrow BNC to a radio's SMA connector, possibly another quarter or third of one db loss. Bottom line - NO PROBLEMS. Both "additions" add up to 2/3 of ONE db loss.

Why doesn't the Arrow Antenna manufacturer post "gain" figures? Well, the emotional part of me thinks, "Heck, it works so great, I don't really need to know ... " But the inquisitive Clint would like to know. I personally have felt that there's about 7-12db gain on the 440 side, and about 4-6db gain on the 2 meter side. THOSE NUMBERS ARE PERSONAL OPINIONS ONLY, and not based on my own personal scientific analysis. But there are a couple "non-biased" tests out there that ARE reporting numbers very close to what I "feel."

ARROW'S YAGI vs. ELK'S LOG PERIODIC - I own both. They both work well for FM satellite work (as well as for Earth-based comms, too!). I have used the Arrow for my demos and presentations the past several years for a couple of (very un-scientific) reasons ...

- The Arrow for me just seems to "capture" the satellite's signal in a more "pronounced" way. (Talk about UN-scientific opinions! (grin)) I mean, when the satellite is rising ... and gets to about five or seven degrees above the horizon ... moving it slowly and pointing it towards the path of the sat gives me that slight audio "deadening" ("capturing" ) sooner than the Elk does. Although this phenomenon IS real to my ears, it is probably something that cannot be measured easily. But audiences hear me say, "There it is ... " well before voices are heard - as the Arrow "finds" the sat's approach.

- The Arrow is a great conversation starter, even if just sitting on a tabletop or mounted on a tripod. It is elegant ... simple ... new ones are a vibrant purple (grin) ... And after adding my Stanley(tm) hacksaw handle to it, it can be more easily passed around to visitors to handle.

POLARIZATION ISSUES - Engineers (darn those engineers!) tell us that there may be up to a 22-or-23db INCREASE or DECREASE in signal strength workin' the FM birds by simply twisting your antenna 90 degrees.

That's the engineers talking. And, on paper, that 22db loss/gain may be correct. But in the real world? It is nonsense. At EVERY demo I have given over the years, and on EVERY pass in my back yard, I talk with stations, and, during the pass, twist my antenna 90 degrees to see if I can "hear" a signal increase or signal degradation using the Arrow. It just doesn't occur - at lease noting that I can HEAR myself.

Elk antenna devotees state that it is easier to turn the Elk 90 degrees to accommodate the polarization issue. And that is probably true. I just haven't experienced this to BE an issue.

I *do* like the job Elk has done with the paint/protective coating on their elements. It is a weatherized sort of black coating. Gives a real "serious" look to the antenna!

SO ... there you go. More info than you probably ever wanted to know about the topic. I am packing up this moment to give my sat presentation to a club in Norwalk, CA this afternoon, it's my "elegantly well-worn light purple" Arrow that is going with me.
