HamShield for Arduino (VHF/UHF transceiver)
Turn your Arduino into a powerful radio transceiver!
HamShield lets your Arduino talk to far away people and things using powerful amateur radio bands! Best of all, the hardware and software is open source!
With the power of Arduino, you can use the HamShield to build and invent amazing things in minutes!
Here are some examples, right out of our sketch toolbox:
Packet Radio
Long range mesh networks
Emergency communication networks
High altitude ballooning
Talk to repeaters
Tracking devices (APRS)
Interface the HamShield to your computer!
Beacons
Weather stations
Repeaters
Remote controlled robots
Automated satellite tracking and reception
Weather satellites
Scanning police, fire, business, FRS, GMRS, and MURS frequencies
Logging and recording radio traffic
Touchscreen handhelds
Bulletin board systems
New inventions!

HOW DOES AN FM TRANSCEIVER WORK?
Take a look at this FM transmitter diagram:
The process is relatively straightforward:
1) The microphone takes the voice in.
2) This voice signal goes into an audio processor in order to create an input signal.
3) The input signal is combined with a carrier frequency that is generated by the voltage controlled oscillator (V.C.O.).
4) The result is a signal that carries our information but is not sufficiently powerful enough to be transmitted up through an antenna. The signal is amplified through two different stages:
5) The exciter stage amplifies the signal power up one level of output.
6) The power amplifier drives it up to another power output level, now sufficient for the transmitter’s antenna.

How to find active repeaters?
Hams have been complaining about lack of activity on repeaters for well over a decade. Way back in 2003 I created a cover of a magazine I was editing (the SERA Repeater Journal) that spoofed the ARRL's Now You're Talking license manual by changing the title to Now You're Missing. See the art for this episode if it shows up in your podcast feed. I also wrote an editorial about the phenomenon in that issue.

How to find active repeaters?
I've found quite a few repeaters in my area but most of them dont really have activity. One has a "Traffic report" at 8:30, and another is cw and some data. But none of them seem to be really active.

Looking for VHF/UHF HT recommendations
While I'm saving up for/learning to build my own HF base station I'd like to get a hand transceiver. The only problem is, there are so many options I have no idea where to begin.
What I'm looking for is:
- Dual-band 2m and 440. There are repeaters locally that support both.
- Digital support. My local club has d-star support built into their repeaters, and a few members use it. I was looking at an Icom ID-51a but if their are other or better options (not necessarily D-star mind you) I'd like to hear them.
- Priced between $250-500. I'm not really interested in Baofeng or the other Chinese brands. I've seen a few and messed with them. They're kinda tacky and definitely show their pricing in their build quality.
I've also looked at a few Yaesu models but I don't remember the specifics of them.

2017 Canada's 150th Birthday. Operators in Canada are allowed
Please note that next year is Canada's 150th Birthday. Operators in Canada are allowed (all year) in 2017 to operate with a special event prefix, that is, every Canadian amateur radio station may be a special event station automatically and with no paperwork.
(I'm just spreading the world early as last time we had special event prefixes, I didn't hear many at all besides myself using them on the air and no one seemed to know about it)
As listed on the Industry Canada site (linked below):
VA can become CF
VE can become CG
VO can become CH
VY can become CI
Any operator with a callsign starting with "VA", for example, may operate their callsign with "CF" instead. For example, VA3RAC could operate as CF3RAC, VE3RAC could operate as CG3RAC, etc.
All of the awards I've played with so far (DXCC, WAS, CQ WPX, WAZ, Counties, etc) all accept different callsigns in a submission as long as it's the same operator/QTH
PSA: Industry Canada permits hams to remove address from online database
IC permits hams to request that their address not be posted in the online databases, Of course, you still have to give them your mailing address and keep it
updated, and redacting a current address will still leave it mirrored
across other sites on the Internet).
callsign application has had a "do not publish" checkbox for years.

I am moving. What are my obligations to Industry Canada and the Amateur Radio Service Centre (ARSC)?
When you are moving to a new address within the same province notify the ARSC by requesting a "change of amateur address" which can be found on the Amateurs and Clubs page. If you are moving out of province and will no longer be retaining an address in the province of your call sign, request a "change of amateur province" which can be found on the Amateurs and Clubs page.
