Baofeng UV-3R Mark II

So, as some of you may have guessed, I like to tinker.  For some reason I’m never satisfied with things the way they are when I buy gadgets.  I have an Acer NetBook running Mac OS X, an old Windows Mobile phone running Android Froyo, and a $50 CVS 7″ WinCE NetBook running Debian Linux.  If there’s a mod, I want to know about it.  I had been reading about the Baofeng UV-3R and its capabilities before I ordered the his and hers models and made sure I ordered a programming cable too, so that I could attempt the 220 mod that’s been talked about.  I ordered the cable from someone different than the radios, so as of Thursday it had not arrived yet.  Could I wait?  Of course not.

I also own a Radio Shack Pro-137 scanner.  This is a 1000-channel model that was marketed as a racing scanner.  You can usually pick them up on the cheap because of the racing moniker.  In reality, these are great all-around scanners, with a stalker function that helps when testing commercial radios.  I have a programming cable for the pro-137 that I used, along with ARC software and a RadioReference account, to load all of the local frequencies I wanted.  I was thinking that day, after dealing with several other forms of USB-to-serial adapters that these cables are not all that different.  Just the pins are different.  The scanner uses a 3-conductor 3.5mm plug, and the Baofeng uses a 4-conductor one.

I examined the pinouts for both radios, and realized that the ground and first ring are the same, but the third ring on the scanner’s plug corresponds to the fourth ring on the Baofeng, so it was probably not going to work.  I know this because when you plug standard stereo headphones into the UV-3R, you short

out pins 3 and 4 in the radio, causing the radio to transmit.  When using headphones though, if you pull the plug out just a little (about a mm), you get one ear (left) of sound.  I wondered if this would work with the programming cable.  I started the software. and hit the button to download the radio memories onto my computer.  After a couple of tries I found the sweet spot.  About a mm out there is a slight detent you can feel.  That is where you need to be.  It works!  I will post the results of my experimenting with the software and the mod later.  If any of you have one of these cables laying around, it will work.  The stock drivers in Vista and Win7 will even work!  Some Radio Shack’s have these on closeout still.  Stock number 20-047.

The funny thing is this:  Guess what was waiting in the mail when I got home?

I haven’t posted so much lately. Sinus issues have kept me from really spending the time on anything other than work and the necessities of life. There are some great goings-on here on Long Island though. My lovely and amazing fiance had been studying for her Technician license for the last month or so. Armed with a notebook, access to the QRZ.com practice tests, and Gordon West’s book, she finally took and passed the exam this past Saturday. Now we just need the callsign.  A friend of ours once told us that there are two types of Ham Radio spouses.  Ones that embrace the hobby, maybe not to the fullest, but will attend picnics and events, and there are the ones that run screaming from it.  I have been blessed with a fiance who fell in love with the Ham Radio community, and the people we have met through it.  I’m not sure that I’ll ever come home to find her staring at Smith Charts, but I think she and I might get to fight over the soldering iron a bit.

Fresh from Amazon

Well, anyway, on to the Baofengs you see here.  She sort-of owed  me a birthday gift for awhile, and I thought she needed a congratulatory gift for passing the exam, so we ordered his-n-hers Baofeng UV-3R Mark IIs.  I know quite a few hams that have purchased these little gems and most are quite pleased.  Now, I understand that I cannot expect the performance of a $300 Kenwood, or other similar HTs, but the value is quite amazing.  Here in the NY Metro area, a small 2 watt HT is not a bad thing to have.

As I do with practically everything I own, I have started the process of learning all I can about getting the most out of these little radios.  I will post the results as I experiment.  So far so good though.  Stay tuned, more to follow.

A reader sent this comment on my post about Heathkit’s demise:

“It would be a limited customer base, as with all the China crap coming in
hard to compete. Also noticed that they are selling 2mt/440 ht’s and
advertising that you do not need a license!!!look for interference to
public service and emergency com, reports against amateur radio, going
to be a tough nut to crack”

I have to disagree.  First of all, some of the “crap” from China is actually pretty good, and giving the “big 3” some serious competition.  You know, there was a time, back in the early seventies when everyone referred to the influx of Japanese-manufactured electronics as crap too.  I remember this first-hand, as my interest in SW and AM DXing started in 1972.  Look where that has gone.  The Japanese are now the manufacturers of choice for our radios.  Now, I cannot say that all of these new low cost radios are good (first-hand experience with a radio from FDC backs that up for me), but the BaoFeng UV-3R has set a new bar for value in a low-cost mini HT, as well as the highly-regarded Wouxun radios.  It should be interesting as these companies evolve.  Mobile radios are just starting to trickle in now, and who knows what’s next.  Outside of radio, what about smartphones?  Where are most of them made?

I watched this same thing happen with Shortwave receivers over the last decade.  Companies like Degen, Tecsun, and Kchibo, first got into this market by being the manufacturers for labels like Grundig-Eton.  The early radios were not good, but then a funny thing happened.  The engineers listened to the public and made changes.  They adjusted the performance and feature-set of these radios based on what the users were asking for.  This is something that their predecessors never did.  Sony, Panasonic, Philips, and even Taiwan’s Sangean, rarely made changes based on the enthusiasts comments and reviews.  The result is that some of the best performing portable SW receivers for the money now come from China.  Panasonic, and Magnavox, are out of the market here.  Sony only makes one viable offering now, and Sangean continues to get mediocre reviews, after such a promising start.  I personally own a few Tecsun, and Degen radios and although the build quality is not quite as good as the Sony, it’s VERY close now.

As far as selling to the non-licensed public, that problem has always existed.  I don’t think that you were required to produce a license to buy any of the HTX radios at Radio Shack in the eighties and nineties, as well as the various commercial offerings they had.  You were told by the packaging, and again in the manuals that you were required to have a license.  Very few people at hamfests and flea markets ask for licenses before taking the cash from their potential customers.  Add to that garage sales, and classified ads, and you can see that the ability to buy un-authorized radio equipment has always been there.  Recent experience with jamming in my area led me to a small history lesson while investigating the source of the interference.  This has been going on for a VERY long time, and you’d be surprised how much of the problem is caused by licensed Hams.

Craigslist, and eBay have made this easier, yes, and I believe that the equipment being sold should at least be restricted to its intended purpose (limiting Xmit frequencies for Amateur equipment), but we will never stop the sale of equipment to the unlicensed public, just as we will never stop music and software pirating.

The biggest travesty here is the existing players not recognizing the changing market.  Kenwood’s new rig is gorgeous, but is another multi-thousand dollar rig what this hobby needs?  What the HF side of the hobby needs is a competent, basic 160-10 (or 6) transceiver that can keep the interest of a newly licensed ham going, with a target sell price UNDER $500.  50-100 watts would be ok at this price-point, with the option of adding some power later.  I honestly feel that if Kenwood, Yaesu, and Icom don’t wake up, and adjust to the changing market, they might go the way of the classic Shortwave manufacturers.

Sorry for the long editorial, but this is a sensitive subject for me.  I have only been a ham for 9 months, and with all of the obligations I have, and trying to make sure there’s something left for retirement, plunking down $1000 on a radio at the moment is out of the question.  Many of our new hams are in this same position.  Instead of having most of us stay as Technicians, it would be nice to get these new hams interested in something other than their newly acquired VHF/UHF privileges.  A General ticket is a fairly small step from Technician, and having some economical starter radios would help

Some of the kits, in my Kit Roundup post fit the bill, but most are CW kits.  The SSB kits available are usually low power.  There are a couple of examples with a bit more power, but fully assembled the price is already in the Alinco DX-SR8 range.  Having said that, the Alinco is probably the closest rig to what I’m thinking of price-wise, but seems to get rather mediocre reviews.  I guess for $519 you can’t be all that picky.

This is all my own opinion of course.  Feel free to discuss in the comments.

Awhile back when I assembled the Amateur Radio Kit Roundup,  I listed Heathkit as a potential source, and even answered a question in the comments about their rumored return to Amateur Radio stating that I would contact someone about it.  I sent an email off asking how they were doing in this regard.  Unfortunately I never received an answer.  Here is some sad news at the ARRL explaining why (courtesy of a mention at eHam.net this morning).  I was not a ham when Heathkit was in its heyday, but knew plenty of people who were, and like most of you, I was impatiently awaiting news of their return to the hobby.  Hopefully this is not a permanent end, but only a temporary setback.

I constantly search for new kit sources for the kit roundup list. Today I stumbled on this one:

One World Trade Center

Here in Manhattan, the highest point above the hustle and bustle, is the Empire State Building. Or, it was at least until yesterday. As of April 30th, 2012, the new One World Trade Center is officially the tallest building in Manhattan. As I listened to the news yesterday morning this got me thinking about the antennas on the Empire State Building, and the logistics and history of them. For those of you fascinated by these things, here are a collection of resources to consult, and some of what I learned about the tallest antennas in the city.

I found a great article on the history of the TV mast at www.lnl.com/esbantennas.htm.  The TV antenna portion was originally a mooring mast for dirigibles which was re-purposed 8 months after the building was completed in 1931.  The article was a reprint from Broadcast Engineering magazine, August 1967.  The mooring mast, which was part of the original design of the building, was supposed to be used by passenger airships for anchoring, while the passengers disembarked down a gangplank to the 102nd floor.  In reality, this proved to be unsafe, as the updrafts and other air currents around the building would not allow for safe mooring.  Only one dirigible ever successfully anchored to the mast after a 30 minute ordeal with mooring ropes, and even then was only able to stay anchored for 3 minutes.  The first entity to transmit from the re-purposed mast was NBC who began experimental TV transmissions from the ESB in December of 1931.  For you fans of  TV’s Fringe, the sequences shot in the alternate universe, show modern dirigibles moored to the Empire State Building, as well as a skyline that still contains the Twin Towers.

Here also, is another great article; from CQ Amateur Radio, March 2011, Digging Deeper With Bill Baker, W1BKR, where Bill visits the transmitter site for channel 13, WNET, in the Empire State Building.  Great pictures of the mast, and of the massive filter network that all signals have to pass through first to reduce interference with each other.

Today there are over 130 antennas on the Empire State Building at various heights.  This site lists the options available to anyone interested in locating an antenna up there.  I’m not sure how many Amateur Radio repeaters are on the building as of today, but one I know for sure is KQ2H.  KQ2H has a large linked network of repeaters that give it incredible range, including a 10 meter input up in the catskill mountains.  I can listen to the ESB 220, 440, and 900 repeaters from my desk at work, and get an idea of what’s going on with 10 meter propagation by taking note of where the incoming stations are.  Lately I’ve been hearing hams from Australia and New Zealand hitting the repeater late nights between 8 and 10 PM EDT.  KQ2H’s 10 meter FM machine transmits on 29.620, and listens on 29.520.  It is usually available on EchoLink, although the link has been down lately.  On EchoLink you need to search for the callsign W2FLA which belongs to the linked 2 meter repeater in the system up in the mountains.

Antenna Mast at the E.S.B. from CQ, March 2011 "Digging Deeper with Bill Baker"

Many of these entities that have antennas on the ESB, relocated there after the Twin Towers fell in the 9/11 disaster.  I was looking for antenna leasing info for the new One World Trade Center building, but nothing seems to be posted yet.  There is definitely going to be an antenna structure on the top of the building though.   I’d love to take a couple of radios up to the ESB observation deck sometime, but I hear the officials can be a little touchy about these things (understandably so).  As I learn more about One World Trade Center I’ll post it at a future date.

Does anyone else out there have stories about antennas on skyscrapers (like the former Sears Tower in Chicago, or even the CN Tower in Toronto)?  Leave some info in the comments.  73.

Stormville Airport Flea Market

Yesterday was opening day at the Stormville Airport flea market, which is about an hour and a half north of New York City.  This to me indicates the start of this year’s flea market season.  What’s available at a non-hamfest flea market?  Well, my radio interests extend beyond Amateur Radio, so I always manage to find something interesting.  I have a small collection of antique transistor radios, and always look for new, and interesting samples.  I picked up a pristine Bulova MW/SW portable last year, which reminded me of a set I had as a kid.  It has been re-capped, and is playing rather nicely.  Some purchases I’ll admit end up on eBay eventually, after a good evaluation and cleaning.  The Bulova is a keeper though.

So, is there anything of interest to a Ham at these events?  For sure!  A smartphone with good internet service is a HUGE help at flea markets.  Quick lookups can tell you a lot about a prospective purchase.  Yesterday I saw a few items, including some test equipment, an SWR meter, and 3 boxes filled with commercial radios and accessories.  Watch the boxes under the edges of the tables for things like comercial radios, especially later this year when businesses and municipalities start dumping equipment that isn’t narrow-band compliant.  The box I found had 450 mhz (not convertible to 440 according to some quick research on the iPhone) and 800 Mhz equipment, but a nice collection of Yaesu and Icom chargers, and some remote speakers.  There was also a Motorola power supply for a mobile, a bunch of batteries, and a bag of about 30 HT antennas.  After talking to the proprietor the price dropped to $100 for all three boxes of equipment.  Reality struck though, and I passed on the lot, since I’m still sorting through the last pile of commercial radios I picked up.

Motorola JT1000 "Jedi"

As far as the Motorolas go, Watch for the VHF and UHF Jedi series radios.  Many of the Jedis can be reprogrammed for amateur use.  Ask around, and I’m sure someone you know through your club, or casual ham contacts knows how to program these.  It requires the correct cable (eBay) and the Motorola MTSX software.  Some of my fellow LIMARC members can attest to my fondness for the Motorola Jedi Series radios, which when successfully reprogrammed make a very nice 2 meter or 440 HT for event use, even if they are a bit heavy.  The batteries will last through a whole event, and then some, and the durability is legendary.  The common models to watch for are: HT1000, MT2000, MTS2000, MTX2000, JT1000, and MTX9000.  The JT model is a great find, since it is actually field programmable.  The 9000, is an inexpensive way to get on the 900 Mhz band.  If you grab one that cannot be reprogrammed for Amateur radio use, don’t fret!  Since most of the Jedis can be programmed to operate narrow band, they can be re-sold for commercial use, and usually at a nice profit.  More info can be found over at Radio Reference.

LIttle Tattler Headphones from oldheadphones.com

One booth had a nice pile of antique headphones.  I picked out a pair of Little Tattlers in fairly nice condition for $5.  These will be used for a crystal radio project for now after getting cleaned up. There were 2 fairly clean Hallicrafters receivers, both S-120s though, which don’t impress me enough to consider.

We headed home with the Little Tattlers, a very interesting old espresso pot, and a bag of wasabi peas.  Nice weather, good company, and an enjoyable hunt for interesting garb.  A successful morning.
