RTL SDR, Ham It UP!, and more

A quick video I put together at BCIT of me messing with my new “Ham It UP!” upconverter for HF signals.


The BCIT ARC is back on BCWARN with a new 5.8ghz data link. This new radio replaces the previous VINE radio which operated at 2.4ghz.

BCWARN is a network of EOC (Emergency Operations Centers) and radio clubs which support emergency communications. The BCWARN network is based on high-elevation sites which act as hub-nodes for the network. These nodes are often multi-homed with other sites, forming a partial-mesh or ring topology. The current network map shows a ring between UBC (main internet gateway and server host), SFU (busiest RF site), and Mount Seymour (Highest elevation location), as well as a ring between SFU, UBC, and a high rise in Burnaby known as “The Boot”. These multiple rings allow for sites to fail without sever impact to other sites in the network.

BCIT is a single homed site as SFU is the only site which BCIT can see reliably. A path to Mount Seymour is not possible due to tree cover, even though the mountain is prominent to the north.

Check out the installation photos, and a time-lapse below:

A special thanks goes out to Jeremy (VA7NSA) and Ian (VE7HHS) who did the tower work. Ground support was provided by Duncan (VE7NEO) and Patrick (VE7SDI) while I “supervised” the stationary camera.

Cheers, VE7WNK

3710 Audio tests from BCIT

Recordings from the BCIT ARC. Many hams were chatting on 3710kc about their audio quality after a station ended up with some RF (maybe) on their signal.

The following is audio captured at 44100hz mono on BCIT’s IC7600 with filters set to 3.6kHz. I have opted NOT to encode this to MP3 as it will ruin the fidelity, so it’s in 16PCM audio.

Link 1: 3710_1908PDT.wav (61MB)

Link 2: 3710_1937PDT.wav (107MB)

Note: There is white space (silence) in the audio, that is due to me transmitting and I have the monitor circuit disabled. Thanks to the BCIT ARC (VE7BFC).

Here is the LIVE audio (well, about 15seconds behind).




It was a good year for 10 meters and 80 meters. From the BCIT ARC I made 514 contacts in a rather small amount of time.

Friday evening I headed to the station around 7/7:30 after finishing dinner and driving down there. On my way I listened via my phone to a local station (VE7GL, Dale) as he worked probably EVERY JA on the band. Once I got there, the first thing I did was spin up 10 meters and found wall to wall stations. By the time I had the N1MM software loaded the band had gone soggy as the grey line had long since passed.

I dropped down to 15 and made about 30 Q’s by hunting for mults and calling CQ a time or two. My CQ’ing was cut short by RF blowing up the computer and getting into everything. Well deserved tho, we are using a laptop as our main station. The RF issues continued as I jumped onto 20, then 40, and eventually 80. By 3AM I figured I should head out, and I made my way home.

The next morning I had plans with some co-workers to take our XYL’s to a pumpkin patch, but all I could think about was picking off rare DX on 10. By 14/1500 local I was back on air and went directly to 10. For the next 4 hours I hopped between 10, 15, and 20, mostly looking for mults. I took some time to call CQ, but found I did better when busting up pile ups. I did have a pretty good run on 28.501 (Giving plenty of room to the DXpedition on 28.490).

Don, VA7LNX came to the rescue, and brought in some toroids to deal with the RF leaking into the USB! Problem solved!

The station stayed empty Sunday as I didn’t get out of my warm bed until after 11 – I was burned out.

Here is my final score after just a few hours invested – maybe 10?

If you look up VE7BFC on ustream.tv you will find some video from the weekend.

Thanks for checking it out.


VE7WNK Remote from a meeting room

Bored in a meeting? Stuck waiting on people to show up? Yup! I dialed into my remote HF setup and listened to some DX on 10meters this morning from a meeting room.
