Swindled by a HAM, yes a HAM

I love working satellites but have been unable to for a bit due to an equipment failure and a lack of a budget.  Then I hear of a dual band radio that is being sold, and it comes with two batteries, a bunch of chargers and no manual.  Price asked was premium for the radio which looked to be in good condition but it had features that I will truly enjoy when working satellites.  Radio turned on and all modes were selectable and everything was looking in order.  Here in lies the start of the problem, how can one properly test batteries in the field when buying a radio?
Needless to say I did not test them

I bought the radio and headed home with the power running out on the first battery about 20 minutes after the purchase.  I attribute this to a “lack of a recent charge?” (at the time) and decide to go for slow charge for 24 hrs when I get home.            
tic-toc…
Radio fires up, key up… repeater talks to me.  Listen to some morning jabber and then the radio beeps and shuts down.  A quick measure of the voltage on the battery revealed that the battery was indeed dead and that the radio was reporting it properly.  Second battery, well… turn out it was not a battery but a battery case that needed new four new AA batteries.  To that I say he and myself rack up the idiot points.  I could have ruined the radio trying to cahrge the alkaline batteries in the battery case. oops. anyway

Long story short, I called the guy I bought it from and asked about the batteries and was told I “musta done something to them”.  Interesting, you mean “besides try to charge them both slow and fast methods?”.  He insisted that I had done something and stated that he had it on for a day or two before I bought it.  Anyway, here is where I went wrong I guess…

I said that “I felt a little swindled” (meaning I paid premium and thought I was getting radio with two good batteries” .   He immediately said I was calling him a liar and calling  him names and he would not stand for that. He then hung up on me.  Had he known what he was selling or just a nice guy he might have suggested some options for me to try but instead opted to loose any future sale with me.

Now being this is exactly what I wanted radio wise, separate tune and separate volume for each band, this poor guy thought I wanted to return it (still kinda laughing at him) but I would have felt like he was more human had he split an ebay battery with me… 
This radio makes satellite communication easier for me but that is for another day as I wait for the ebay batteries to arrive.
As for this “HAM” guy that sold me the radio, well I wish him the best as it seems he has his own issues…
Anyway you look at a HT with no batteries sucks and this guy inferred that I fried the batteries(2 of them) and then got offended when I told him how I felt swindled…

I love the radio BTW…

I just paid more than I would have paid had I known I had to buy a battery in order to use it at a decent output (9.6v factory battery vs the 6v AA battery case) The Radio is an Icom IC-w32a and is great for amateur satellite communication.

Chalk it up to a lesson learned.

BARC and Jeffco ARES in Alabama before and after the tornados

Pleasant Grove Alabama Tornado 2011-Devastation for milesI was impressed by the immense turnout on the BARC(146.88 tone88.5) repeater in Birmingham Alabama as the storms approached. Storm spotters reporting in, various other ham radio operators reporting conditions. The unity and control of the net was obvious. I listen more than I talk and enjoyed being a fly on the wall. This disaster is one that I personally will never forget for many reasons.

The main reason I will not forget this disaster is because of the voices on the radio that I heard throughout the disaster helping people they may never meet or see. Communicating across great distances where other forms of communication failed us. I especially noted N4HUB and WX4RON, two well trained and caring people that have great experience in the radio community. Though no one would wish this kind of devastation on anyone the two individuals were ready for the challenge of the tornados and the chaos that ensued. These two coordinated a large network of volunteer radio operators across the state in the recovery and support operations. There hard work justifies this hobby for all of us. They exemplify what all of us should do with this great hobby. All of us need to be prepared for a disaster and the preparedness of BARC, Jeffco ARES, Many unnamed ham radio operators not only saved life’s but helped many agencies including the EMA and the Red Cross. Well done N4HUB and WX4RON! Your leadership during this disaster was unparalleled. I am sure I am not the only one to say this but, Thank you for everything you guys do!

Biggest solar flare in years set to blast Earth’s atmosphere; could impact GPS, communication, power grids

The Sun is reaching out to us…Monday’s eruption, considered an X-class flare, is the biggest solar flare in four years. It is already being blamed for disrupting radio communication in China, and could potentially affect power grids and satellite communication around the globe.

Solar flare to hit earthA massive solar flare could make for a beautiful night for people in the northern United States – provided it doesn’t knock the lights out.
Common sense but, if you don’t need to have it(computers,radios,chargers,etc) turned on or plugged in right now, you should go ahead and turn it off and unplug it. I am not a “doom and gloom” kind of person, more it just makes sense that if there is an event (this thing hits us) and the device is not connected to the grid it will be more likely to survive. I digress…

The blast of charged particles unleashed from the sun earlier this week has been peppering the Earth over the last few days, but it’s biggest punch is expected to hit the Earth’s atmosphere on Thursday.

Monday’s eruption, considered an X-class flare, is the biggest solar flare in four years. It is already being blamed for disrupting radio communication in China, and could potentially affect power grids and satellite communication around the globe.

However, for the United States, the most likely outcome from this latest space storm could be a colorful night sky over New England and even parts of New York State.

“It won’t hit us dead-on,” physicist Dean Pesnell, project scientist for NASA’s Solar Dynamics Observatory, told National Geographic.

The moon may make it difficult to see, but stargazers may be able to catch a reddish glow among the stars.

x-class solar flare will not be a direct hit“X-class flares are the most powerful of all solar events that can trigger radio blackouts and long-lasting radiation storms,” NASA said on Tuesday.

The China Meteorological Administration reported that Monday’s solar flare caused “sudden ionospheric disturbances” in the atmosphere above China and jammed short-wave radio communications in the southern part of the country.

And Xinhua, the official Chinese news agency reported there was a high probability that large solar flares would appear over the next three days.

Solar flares in 2006 are blamed for causing disruptions of GPS systems, according to New Scientist magazine. Another in 1973 knocked out power in Canada, impacted six million people.

IFR am/fm-1200: Two-way radio repair, not yet (update 5 more pictures)

IFR am/fm-1200 arrived on time as expected but the IFR am/fm-1200 has more issues than the seller lead me to believe. I am still hopeful that I can figure this one out but at thispoint I am a little bit frustrated. I am still looking through the various boards and changing out the fuses. Maybe I will get this service monitor up and running soon… maybe not.

Edit 1 (1 hr in): 3 fuses later the unit is up and running in a basic FM narrow receive mode. Audio is good and receive seems to be on frequency. Scope seems to be having an issue and I have found multiple broken parts. The IFR am/fm-1200 is missing the antenna, AC and DC power cords, operation manual (3 ring binder is present but manual has been removed). It does have the Illustrated Parts Catalog for the fm/am-1200 communications service monitor.

Edit 2: Well, was able to tune a few radio but have no spectrum analyzer working.  When I turn on the scope I get a checksum error and then a memory error.   I sent an email to Kurt Graber at KG electronics but he is a business and suggested I ship it in.  Not much help there I guess unless I just want someone else to do it.  I will take the scope out and take a look at the power control board for it.  Surely I will find the melted part (at least one would hope…).  So for now the IFR FM/AM-1200 sits here on my desk, is able to do a variety of things but is without scope.  The scope on the IFR communications monitor is something I was looking forward to using so this is a pretty big set back. 

Sidenote: Sent an email to the person who sold me the device, they claimed another issue was “only” thing wrong with it.  Feeling a little burned at the moment, no pun intended. Now off to find the burned parts…..

ifr am/fm-1200 scope power supply board burned resistorifr am/fm-1200 scope power supply board burned by resistorEdit 3: Found the issue in the power control board of the IFR am/fm-1200. Now to decypher the results as my schematics do not match but I am 99% sure of the resistor in question… anyway here are the pictures, note the heavy board burn where the resistor on the ifr am/fm-1200’s spectrum/scope power supply shorted.  I imagine the smoke would have been a dead giveaway that the service monitor was in need of some internal love.  

Edit 4: in looking at the entire board and tracing out the current flow I have found more suspect parts, in particular is a irf520 that seems to be shorted. I am reviewing the spec sheet for that part and will be running some more tests.  Pictures are here and you can see the heat bubble in the pcb board where that resistor had overheated and failed.  following the schematics of the ifr am/fm-1200 I found that the source of the overvoltage in the resitor was the irf-520.  It is reading a short(see pictures).

Another view of the irf-520 is shorted and burned on the scope power supply in my ifr am/fm-1200

this spectrum scope power supply pcb board got hot enough to bubble. damage is still being assesed

  Thank you for all the great support and emails!  They have been great and very helpful!  Keep them coming!

more to come

P.S.  If you have any ideas or have one of these yourself, I would love to hear from you!!!

Thank you

more to come soon…

NASA seeks Amateur Radio operators aid with NanoSail-D

NASA seeks Amateur Radio operators’ aid

The US Space Agency NASA has asked for the help of Amateur Radio operators to help in receiving the signal from NanoSail-D on 437.270MHz.

The NASA Press release says:

Wednesday, Jan. 19 at 11:30 a.m. EST, engineers at Marshall SpacemFlight Center in Huntsville, Ala., confirmed that the NanoSail-D nanosatellite ejected from Fast Affordable Scientific and Technology Satellite, FASTSAT. The ejection event occurred spontaneously and was identified this morning when engineers at the center analyzed onboard FASTSAT telemetry. The ejection of NanoSail-D also has been confirmed by ground-based satellite tracking assets.

Amateur radio operators are asked to listen for the signal to verify NanoSail-D is operating. This information should be sent to the NanoSail-D dashboard here .

The NanoSail-D beacon signal can be found at 437.270 MHz.

The NanoSail-D science team is hopeful the nanosatellite is healthy and can complete its solar sail mission.
After ejection, a timer within NanoSail-D begins a three-day countdown as the satellite orbits the Earth. Once the timer reaches zero, four booms will quickly deploy and the NanoSail-D sail will start to unfold to a 100-square-foot polymer sail. Within five seconds the sail fully unfurls.

VX-7r out of alignment

Misaligned vx-7r – Not really sure what I did but my vx-7r is out of alignment and is picking up interference (voices barely breaking squelch but distinctly talking/dispatch). This pains me as I love this radio and use it EVERYDAY in dual band mode (monitoring two bands with scanning). Thus I broke out this procedure… Will be trying it and reporting back the results.
edit 1: Was able to connect the vx-7r to an fm/am-1200 (ifr-1200) communications service monitor. I was able to adjust the pll loop lock but found an issue in the IFR fm/am 1200 service monitor. yep, no fun. Will be leaving the rest of the setting alone for a bit while I address the IFR-1200.

Alignment of a Yaesu VX-7r

Setting up the vx-7r for the tests/alignment

Set up the test equipment as shown below for transceiver alignment, and apply 8.7 V DC power to the transceiver.

Internal System Alignment Routine
This uses a programmed routine in the transceiver which simplifies many previously complex discrete component settings and adjustments with digitally-controlled settings via front panel buttons and LCD indications.

  1. To begin, set the transceiver to the center of the 50 MHz, 144 MHz, 222 MHz and 430 MHz bands.
  2. Next, select the 430 MHz band, then turn the transceiver off.
  3. Now, press and hold in the MON/F, “link/internet”and 0 buttons (at the same time) while powering the radio on again. The display will show the first setting. Thereafter, the frequencies used during alignment will automatically be set without action by you.
  4. In the alignment process, each adjustment is selected by rotating the DIAL. Alignment is performed by:
  5. Pressing the V/M button;
  6. Injecting a signal of the required frequency and level; then
  7. Pressing the V/M button after a level setting or adjustment is made. This second pressing of the MON/F button stores the entry.
  8. To exit the alignment routine, press the HM/RV button.

After performing the system alignment in its entirety, individual settings can be returned to and adjusted should the need arise. As each vx-7r transceiver is individually optimized at the factory, the precise settings for the transceiver on your bench may be slightly different.

Italian amateur radio repeaters impact satellite operations by disregarding the IARU bandplan

Italian amateur radio repeaters disregard IARU bandplan

In Italy, FM and D-Star repeaters are being licensed in the 2m IARU Amateur Satellite segment 145.8-146.0MHz causing considerable interference to Amateur Radio Satellites and the International Space Station.

It would appear that the Italian regulator permits repeaters anywhere within 2m on a provisional basis for 60 days. Authorisation may become permanent if no complaints are received. It would appear it is up to Amateurs worldwide to make sure the Italian regulator is made aware of any problems.

Repeaters in 145.8-146.0MHz cause interference to both satellite transponders and to the important satellite control uplinks.

Communications via Amateur Radio satellites are possible using as little as 300mW to a quarter wave whip as demonstrated by EB4DKA on SO-50 – uplink frequency 145.850MHz, see
http://www.southgatearc.org/satellites/eb4dka.htm

In fact, contacts using as little as 50mW FM have been achieved via the Amateur Satellites. Any repeater operation in the satellite segment, no matter how low power, will block the transponders and critical satellite command and control systems.

Some of the Italian repeaters operating in the 2m Amateur Satellite allocation are:

Readers concerned about the blatent disregard of IARU bandplans are invited to make the Italian regulator aware of the international interference that repeaters operating in 145.8-146.0MHz cause. Email should be sent to:
