radio
I am a ham radio operator since October 2010, when I passed my "Basic
Qualification" in Canada, which gave me the callsign VA2ANK
.
I also volunteered at CKUT for a while, but I didn't have time to commit long term. It was still a pretty awesome experience. See communication for more details on that side.

There's a great guide on how to setup a mobile HF rig that I could reuse with my FT-100d. It seems I am missing:
- a (smaller, automatic) antenna tuner
- a Condor pack insert
- a Bienno LiFePO4 battery - smaller, lighter and safer than SLA batteries
- some sort of powerpole adapter for the FT-100d, maybe this thing from Powererx?
That guy also made an emcomm kit guide (emergency communications) that we might want to learn from. In particular, it ships:
- a UV-5R USB charger
- a Nagoya UT-72 magmount antenna with RP-SMA connector
- a waterproof box - i would rather use a metal box to provide some sort of shielding, some people use ammo boxes for that reason
- the ARRL repeater handbook, which does include Canada listings
- a tutorial card
- the radio's manual
- a bandplan
I did a review of FmTransmitters a long time ago that is probably now completely useless.

Quad antenna project
I was working on building a new antenna. It was based on this design, which uses a mix of PVC pipes and fiberglass rods, except I adapted it to a 20m antenna and replace the PVC with aluminium for solidity. It should be possible to take the antenna apart and rebuild it if necessary.
I have mostly lost the parts to this and it's now just an old crazy project that never materialized. I'm keeping it here for future reference and to inspire other people to do crazy things like this.
Parts list
Mast
Part | Amount | Where | Weight | Price | Notes |
---|---|---|---|---|---|
tripod | 1 | addison | ? | 45.56$ | ~2' x 2' |
3m steel pole | 1 | downstairs | ? | 0$ | to connect the boom and tripod, 1-1¼" |
sandbags | 3 | home depot | 30kg ea. | 10.76$ | one per leg |
plywood | 3'x4' | attic | ? | 0$ | |
Mast clamps (1"3/4) | 4 | hardware store | ? | 4.92$ | to connect the boom with the mast, bigger mast, 1.23¢ ea |
Mast clamps (1"3/8) | 2 | hardware store | ? | 1.60$ | to connect the boom with the mast, 80¢ ea |
guy rope | 2x100' | hardware store | ? | 63.98$ | to secure the mast, using poplypropylene/nylon rope, each line should support around 300lbs of pressure, enough for the 500lbs of pressure with a 90mph wind |
Antenna and accessories
Part | Amount | Where | Weight | Price | Notes |
---|---|---|---|---|---|
1" hose clamps | 8 | home depot | ? | ? | to tie the antenna line to the spreaders |
tie wraps, small | 100 | hardware store | ? | 3.09$ | to tie the antenna line to the spreaders |
2"½ hose clamps | 19 | hardware store | ? | 26.41$ | to tie-up the boom together (2), the spreaders to the spider (8) and the spreaders themselves (8), +spare (1) |
8"x½" plastic tube | 1 | home depot | ~0 | 0$ | for spreader/wire attachment - found some |
15' 1¼" fiberglass | 8 | mgs4u.com (type 1) | 17.6lbs | ~160$ - actual: 255$CAD (!!) | 4.4lbs ea, unit price 19.80$ |
Clamps | 10-pack | dxengineering | ~0 | 14.95$ | to secure the feedline |
4m aluminium boom | 2 | DX engineering | 2.5lbs | 24.90$ | |
500' of wiring | 1 | DX engineering | N/A | 74.95$ | only parts of this will be used (120' to be more precise) |
U clamps and bolts | 4 | |
~0 | 0$ | included in the beam/pole fitting |
boom/pole plate | 1 | Rick Adams | ? | 45$ + 30$ shipping | need to drill holes, includes reinforcement pole |
spider | 2 | Rick Adams | 2.3lbs | 70$USD | 14oz ea. 40$/ea, seems strong and sturdy, and Rick helped me through email, let's try! |
Total planned price: ~373.77$
Total planned weight: ~25lbs++ - not including 180lbs of sandbags, the pole and tripod.
Notes:
- Gauge: 10-16 AWG is okay (see AWG, that is 1.2-2.5mm or 1/10" - 1/20"), and can be insulated, according to this page
- Using welding wire is a good idea, as the lightning bolt quad uses
- I was suggested Dubo for electric supplies
Current blocker(s): Waiting for parts to be shipped and for the rain to stop.
Discarded approaches
Those parts were considered during the design phase but were discarded for various reasons.
Part | Amount | Where | Price | Notes |
---|---|---|---|---|
welding wire aluminium | 270' spool | canadian tire? | ? | example: Aluminium 5356 MIG alloy - too hard to find |
|
1 | home depot | ? | according to Rick, this could create interference |
|
2 | creativeshelters.com | 3.08$ | couldn't order, they don't accept canadian zip codes, and shipping is 30$ anyways, and I don't trust PVC |
|
8 | home depot | ~5$ | we'll use tie-wraps instead for spreader/wire attachment |
|
4 | home depot | ? | PVC pipes are too flexible to hold properly, we need fiberglass |
|
44.4m | ??? | 29.32$ (addison?) 48.64$ pour 2x12 22m (dubo) | |
I had a lot of problems finding proper parts (pipes, raw materials like wiring and so on) in Montreal, which made building the antenna quite tricky, as a lot of things needed to be ordered online, which raised the overall costs because of shipping.

This needs to be merged into Software

- minimuf - allows you to compute the WikiPedia:MUF depending on salar activity and so on, but has an unusuable interface (you need to enter a series of digits... how about a GUI?!)
