I Like Blue

I didn’t really like the yellowish backlight on my VHF/UHF SWR Meter so I opened it up and grabbed a blue LED to replace it with. I added a small toggle switch as well so I can power the backlight off without having to unplug the power from the back.

It had 12volts already coming in from a power supply so I had to find the right resistor to use on the LED. It is a basic formula:

To calculate the resistor needed for a simple LED circuit, simply take the voltage drop away from the source voltage then use Ohm’s Law.

  • Es is the source voltage, measured in volts (V)
  • Eled is the voltage drop across the LED, measured in volts (V)
  • Iled is the current through the LED, measured in Amperes (Amps/A)
  • R is the resistance, measured in Ohms (Ω)

so..  R=(Es – Eled) / iled

If you don’t want to bother with that you can go HERE

I needed a 560 Ohm resistor to make my LED work on 12volts

I just like the blue backlight!

Wish I had a little smaller switch to use but it gets the job done.

HAMFEST TOMORROW!

I am hoping to find a decent deal on an Antenna Tuner there and other goodies! Be nice to win that raffle as well but it will all be fun going to my first Hamfest.

First Radio

A couple days before I took my test I had also received my first radio. To start off I wanted to get on the 2Meter band being as I could talk phone right away with a Technician’s license and I would be more likely to make contacts on local repeaters than trying on 10meter sideband right off. I was skeptical at spending too much right away as I didn’t know enough about what was to be had out there without a further education.

So after reading quite a bit on forums and reviews I decide to give the very affordable BaoFeng UV5R+ a shot.

It is a tidy little Handheld with most the features you need or would want. Programmable via cable or keypad, scans frequencies or memory channels and even has a flashlight and a decent Fm broadcast radio.

I found the best price on Amazon  I picked up an programming cable, Mic and a TRAM model 1185 mobile dual band antenna for my Jeep. This is a lot of radio for 40 bucks is all I can say. 2Meters, 70CM bands. Can be used as police scanner, FMRS and MURS radio.

The stock software leaves a lot to be desired so I downloaded CHIRP and it works very well. I can load up repeaters from various sources and save the image of the radio etc. On my recent honeymoon through the Olympic Peninsula here in Washington State I was able to load up my radio with repeaters based on the counties I was going to be driving through.

I use this mostly at home with an outside antenna. Radioshack is among the many places you can get an adapter for this radio to connect to a PL-259. I built a couple different groundplane antennas that I have used to participate in a few local area Nets. I do have a little bit a trouble hitting all the repeaters which I thought was due to coax loss but a few tries in the car and just out in the yard with stock antenna I still feel a bit under powered.  I run into a lot of I can hear them but they can not hear me. I am keeping my eyes out for a mobile with a little more power or a linear amp.

I had picked up a Daiwa CN-103L SWR/Power meter from a friend and both of the antennas I have made tuned up nicely, so I will connect to the repeaters I can until I get a few more vhf/uhf watts under my belt.

Here It Starts

ImageGreetings!

I recently received the Call Sign KG7FDJ after passing my FCC Element 2 Technician test enabling me to operate an amateur radio on certain frequencies.

I used to be avid blogger about 10 years ago and have recently been looking for something to write about again. I like to write, I like most of you I have an opinion and like a lot of other older internet users I began my writing on the internet by being active with my opinion and words on forums and networks of blogs. Most of the words read or written had a certain heat to them fueled by politics and religion. Since those days I have lost most of my emotional energy to muster up a public opinion. My need to express my opinion was kept in check by my wisdom. My dad always told me never discuss politics or religion, little by little I listen to my father even though it takes me roughly 20 years per piece of advice.

Ham radio, electronics are some of the things that occupy my thoughts and I want to document my progress into the higher FCC amateur licenses, the things I am going to learn, the things I might pass on and the fun I am going to have.

So welcome to my words, hope to read yours and hope you enjoy reading mine.
