One of my favourite hobbies is Amateur Radio. I am currently a licensed Amateur Extra, K6QT. My call sign originates from the California area, even though I am from 7 land in Utah. This call sign is a vanity call sign, one that can be hand-picked by the ham radio operator. The reason I picked this call sign is that I got tired of people repeating back to me my call sign wrong when I had AB7XT and NZ8C. I had so many letters that rhymed with e that people would always hear it wrong. Now I just have to tell stories about what I'm doing out here in Utah with a "6" call sign :).

 

Ive been in Amateur Radio since 18 April 1997. I got my Tech Plus on that day. Exactly 364 days later, on 17 April 1998, I received my Amateur Extra license. I passed it by the skin of my teeth. I got 7/10 questions right on the multiple choice test for 20 wpm (words per minute) Morse Code, which still had to be done in those days. The written exam was a bit easier, which I got 100% on. I also love the code, but it was tough in those days!

 

Other call signs I have had through the years are:

 

1.    KC7VYQ (Tech Plus)

2.    KC7VYQ (General)

3.    KK7JX (Advanced)

4.    AB7XT (Amateur Extra)

5.    N3JX (Amateur Extra)

6.    NZ8C (Amateur Extra)

7.    KO3U (Amateur Extra)

8.    And now currently: K6QT (Amateur Extra)

 

Im active and in charge of the in the Chelsie Park portion of the West Layton ERC, West Layton, Utah. Am working with my 8-, 9- (twins!), and 11-year old kids to get their ham licenses.  One just got his Tech 2 Jan 2010 and his General on 20 Jan 2010.  He first picked up a book only last Christmas Eve. Within a week, he had his Tech ticket and less than three weeks later, his General. We're studying his Extra now. He doesn't seem to get enough of it, so we're going to try to get through the world of polar coordinates, amateur bands, and mode types to try to help him get his Extra ticket by summer 2010. He is N1JSE (formerly KF7GXE). The twins passed their Techs, as well, although poor Seth had to take the test quite a few times before he passed. But they are now N2JAE (Jared) and N0SRE (Seth). Isaac will wait for a year or two to get his license. They're very excited little guys and I already have radios for them, which they are coveting! 

 

The General son is interested in EME, so we may set up a station at our cabin in Wyoming to do just this.  1500 W, some special software, and a good antenna is supposed to be all you need to do EME.  I've seen many of the huge antenna arrays used for this, but it's pretty discouraging if you need setups that only big companies and universities can afford to do it. 1500 W on 2M require an RF safety distance of 100ft away from the antenna at 100% duty cycle, but the average power is probably more like 57 feet, if you are holding a conversation. LMR-400 is rated for high power and is not at all a "lossy" cable, especially at higher frequencies, as well, so we've been lucky to have the things available to us that we need. Now the only trick is getting enough money for the projects.

Mainly I have worked with VHF/UHF phone, but am getting now into HF, and am interested in RTTY, packet, and some other things.  Am getting a new Hy-Gain AV-18HT 53 ft. vertical.  Thank heaven, the local CC&Rs and the city are fine with this.  This is a real thrill, since Hy-Gain touts this vertical as being the "best amateur vertical in the world".  With 60 radials of 32m long each, it's going to be 1920 m of copper wire, well over 6000 ft. (multiply m by a factor of 3.28083 to get1 ft.) and run me a nearly $400 hundred more dollars, just for the wire!  If I went with the specs that the FCC requires broadcast stations to operate at, they need 120 radials minimum at .4λ, costing me around $1700, if you can believe! The cement and truck to get it in for the antenna base will be a couple hundred more.  And since Hy-Gain doesn't ship something that big through the mail, they have to truck it in, which will cost over $200 more.  The antenna, with the 17M and 160M kits runs over $1100.  Wow, it will definitely be a couple of grand before I get this antenna up and running.  But I hear it will be worth it. 

I also have a Yaesu FT-7900R for the car (and am planning to get the exact same radio for the van in a few months) and have brought my FT-857D in from the car to the shack.  I haven't found much use for HF in the car up to now. I do 99.99% of my mobile communications on VHF/UHF anyway, so this is the route I've chosen. I'm also looking at an Ameritron AL-1500X (I'm hoping to get the export variety) power supply that will pump out 1500 watts (actually 2500).  The range of bands with the FT-857D is great.  If I remember correctly, it goes from 160 M to 70 CM, except for 1.25 M.   Not sure what the phobia is to 1.25 M.  I know rigs are not using it worldwide, but it could at least be used more here.  Same with 33 CM.  It's necessary to get an engineered radio on 900 MHz to be able to use the ham frequencies. There's an MFJ-4605 Window Feedthrough panel, which I can use to get my wires outside without breaking my windows or drilling through the wall. An Antenna Analyzer I've been told is a must, though as I add pieces I see the price cranking up. An MFJ-269 covers 1.8-170 MHz and 415-470 MHz, although I am obviously missing the 1.25 M band with this one, which I love to use partly because it's so dead (i.e., private) and partly because it's something new and up-and-coming around here, and there are a lot of exciting new ways to get involved. I might even put up a repeater on top of a tall peak here. One nice thing is that we are soon to get another 1.25 M repeater in our area. As of now, it's summer 2010, so I'm looking forward to this with a great deal of anticipation.

I also have been involved in commercial radio and have several licenses:

GMDSS Radio Operator/Maintainer License:  DB00000391 (this license and the next two with Ship Radar Endorsement)

General Radiotelephone Operator License:  PG00016801

2nd class radiotelephone:  T2GB064388

GMRS:  WQKW341

Am also a certified ARRL instructor.

Also an ARRL member since about 2005.

I'm extremely interested in the 900 MHz (33 CM) band. A fellow in Vegas is converting Motorola Spectras to ham and selling them for around $175.00 on Ebay. He is a reputable guy from Las Vegas, Blayne, KG7SS, whom you can look up on www.qrz.com.  His e-mail is:   kg7ss@cox.net.  I intend to get one of his Motorola Spectras when I have the chance. I hear they are some of the easiest to convert to ham.  There is a great club in the San Diego area, which is active in 900 MHz and looks like a great contact. Just google "SD 900MHz ARC (San Diego 900 MHz Amateur Radio Club)".

I'm also very interested in the 1200 MHz (23 CM) band and would like to get a mint condition radio from a seller back east that is meant for mobile use at 10W.  That would be a nice little gem for the car or the shack.  It's a Yaesu FT-912R and looks very nice.  This is a ham radio that the Japanese made back in the 90's, but is not manufactured any more.  I am have a little Alinco HT that transmits 300 mW on this band, and as far as I know, is the only equipment currently manufactured for this band. Update: Actually, there is an Icom radio, the ID-1, which is new this year and will work with the 23 CM band. It is D-Star ready radio. It provides digital phone and data, but will also work with analog. It's pretty cost-prohibitive at the moment ($929.00!), but it will certainly come down. Also, think there are other 23 CM radios coming out this year.

I'm also quite interested in the 1.25 M band. Although there are precious few repeaters to use, it's very nice and private, and there are actually some repeaters to use around here. Jimmy and I enjoy using it quite a bit, even if it's simplex that we use.

So 1500 W, SSB with a .5 averaging time would be 1500*.2*.5=150 W only! When you calculate 150 W av. power on this site, with an antenna of 6 dBi gain on 30 MHz, you come up with a safe RF distance of 2.2 m (controlled environment basically, within a hams domain, home) or 4.9 m (uncontrolled environment outside that domain).
