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.

LED light bulbs cause RFI
Last week I purchased 3 two packs of FEIT BR30 LED bulbs from Costco. I was really happy with them at first, very bright, instant on - not like the florescent bulbs they replaced. However, over the last few days I have become aware that I can not listen to our weather radio, an FM radio, or HF radio with these bulbs on. They totally block out the wx radio, they produce a lot of noise on FM radio, and they increase the noise level on 14m by 5 S units. I am therefore taking these back to Costco for credit. I have also contacted FEIT Electric about this and await a reply. They need to do a much better job of engineering the power supply circuitry so they do NOT cause this harmful interference with radio communications.
BTW, I also tried installing ferret core snap on filters to the power leads in the can lighting, but it had no affect on the noise. .

DMR Plus North America - DMR-MARC and DMR Plus partnership
DMR Plus is the original network that developed tools to interconnect Hytera and Motorola repeaters. It has been popular in Europe for years but now, with the cooperation of DMR-MARC, it has finally arrived in North America and the South Pacific. The DMR Plus architecture is similar to D-Star. Users have talkgroups to converse, to disconnect, and to monitor channel status. Users choose from a large pool of reflectors and move back to the converse talkgroup for all QSOs.
The DMR-MARC and DMR Plus partnership is ideal. The DMR-MARC network is robust and reliable. The DMR Plus network is more aligned with experimentation and interoperability of technologies. Think of DMR Plus as the best possible implementation of the former DMR-MARC Sandbox.
DMR Plus also supports a configuration that features the traditional DMR-MARC talkgroups like Worldwide English, North America, Latin America, etc. on TS1 and the DMR-Plus reflectors on TS2. The USA Regional talkgroups and the Canadian Provincial talkgroups are now connected to the TS2 reflectors.
DMR Plus supports connectivity via the DV4mini USB hotspot and the DVMEGA add-on board for the Raspberry Pi. DMR Plus also features MMDVM connectivity. Be sure to visit the Contact Us link at the top of the page and join either Traditional DMR-MARC or DMR Plus North America. You asked for more control over your repeaters and now you have it!

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.

LED Lights In The Shack | Amateur HAM Radio
LED Lights In The Shack Utilitech Pro Soft White LED Bulb
A recent posting by Phil, KO6BB, to Yahoo Group's ndblist, described his recent search for some LED lamps to replace the CFL's in his shack / radio workbench area. If you have been wondering how much RFI that LED lamps might be producing, you may find Phil's findings of some value.
"Recap
I had a 60W equivalent CFL in the floor lamp directly over my operating position. I'd tried a 100W equiv one but it was extremely noisy! Also a couple CFLs in the ceiling lamp.
This is a floor lamp with a crookneck at the top and a triangular metal shade reminiscent of the old style desk lamps, bulb is horiz to the floor. I've used it for years and like it because it places the light directly over the operating position work area (keyboard, radios etc). The actual bulb was about 4.5 inches from the front of the Softrock SDR receiver (in a plastic case), with the base of the lamp (where the electronics are) about 7.5 inches (somebody asked about the distances).

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.
New and Old Regulations and Policies
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.
