Colorado Governor signs Amateur Radio antenna bill into law
Friday the 13th turned out to be a lucky day for Colorado hams, as Gov John Hickenlooper signed into law an Amateur Radio antenna bill that mirrors the PRB-1 federal pre-emption policy.

The tallest towers in the world
Name the tallest structures in the world. You’re almost certainly not thinking of TV towers. But dozens of nearly anonymous towers around the United States, most in small rural communities, dwarf all but the tallest man-made structures in the world.

Reviews

Baofeng FF-12P (UV-5X)
A clip on YouTube suggested that the UV-5X / FF12P scans faster. This proves to be true: the FF-12P outperforms all other Baofeng radios I own, including the GT-3 Mark II. Scan speed is about 5-6 channels/sec.

SSTRAN AMT3000 AM transmitter kit
The AMT3000 can be configured to work with the supplied simple wire antenna, which will essentially broadcast AM to radios throughout your home, or it can be configured for a Part 15 compliant outdoor base-loaded vertical antenna which will extend your range up to 3/4 of a mile, should your shack be down the road or in an outbuilding.

FT817 replacement?

I have mentioned this before, but I am truly amazed that Yaesu has not updated the FT817.  OK, I have heard the “if it ain’t broke don’t fix it” argument but on simple commercial arguments I think they must be stupid. There is a worldwide market (500000?) ready to upgrade yet I think they have now missed the window of opportunity as sunspot numbers are falling.

I wonder if any sharp eyed, sharp eared readers have heard any rumours of an imminent replacement?

Severe solar storm

We are currently experiencing the most severe solar storm in very many years with HF very badly disturbed. There are auroras expected far further south than normal. This is a result of a CME event on the Sun interacting with the magnetic field of our planet.

If the weather is clear, check for a visual aurora!

It is also worth keeping eyes and ears alert for auroral propagation on 10m, 6m, 4m and 2m. I have in the past worked stations via aurora using QRP SSB and CW with very simple wire antennas on 10m and 6m. As frequency goes down SSB becomes more possible. What may be a very rough hissy CW note on 2m maybe a fairly decent SSB signal on 10m. The 10m and 6m bands are very worth a try when there is an aurora about.

PI Day Outing with the PRC-104 3.14.15

Saturday being PI Day 3.14 on the calendar and with still major remnants of cabin fever after what seems to be a very long and never ending winter I decided to head out to a place South of Thunder Bay towards the ON/MN border.

The site is located off of Memory Road and is a slight walk up to the top of the hill and from there is a beautiful look at Pine Bay and Lake Superior.

VE3FAL_PM Memory Road Lookout3The wind was quite strong but at 4C and bright sun peeking through the clouds made this outing a great one.  I snowshoed in as the snow was soft but had to take them off when I got to the hill for the last part of the climb to prevent sliding down. Once at the top the view is awesome, there is also a Shrine that was built many years ago now and serves as place for people to go and share some thoughts I guess, as well on the way up are benches for resting with the words, LOVE,HOPE and FAITH on them, As well there are various pictures of Jesus carrying the cross.

VE3FAL_PM Shrine Memory Road

I brought my PRC-104 with me and the PRC-74 antenna with counterpoise and figured that since we were in the time frame for both RaDAR and the HFPack roundup on 18157.5 I would call CQ if the band was not busy, I used cw first and was able to work KC5UN, after that I worked WB4ETT on voice. I then tried the other bands but no joy. I then went and checked into the MMN on 20 meters on 14.300 and checked in with NCS.

So once again another good day to take the radio out and enjoy the day and just to get out. The video of my outing can be seen on my YouTube Channel at:

I do say Trout Bay in the video but it is Pine Bay, Trout Bay is just a bit further down the road from where I was but is also a bay along the shores of Lake Superior. I thanks all those who listen and work me, and for all the others who enjoy the hobby as much as I do. Portable Ops have really taken the front seat for me and I have no ambition to be cooped up inside the house in a room, but would much rather be outside. The cold I can kinda deal with in my outings, but come summer it brings along the mosquitoes, ticks and blackflies that really have no way to stop or get away from, unless you wait till after 11 PM at night when things cool off and the bugs slow down. But lets see how things work out. See you all down the logbook and have fun. Next RaDAR event is April 4th and I look forward to operating from the same place my winter survival shelter is located near Prince-Jarvis Bay.

Changing propagation

If proof were needed that we are now on the way down to the next minimum then take a look at the sunspot number graphs at http://www.solen.info/solar/ .

Although conditions are sliding, do not abandon the higher HF bands like 10m. There is (usually) quite a lot of good DX around still. In the last solar minimum I was still able to work well into southern South America on 10m with QRP SSB.  WSPR should be even more reliable when conditions are edgy.

I really do hope a strong core of WSPR operators stick with 10m as, in many ways, in the poorer times are when WSPR will be most valuable as a tool. I am hoping that when not on traditional modes like SSB or CW people will still WSPR so we can catch fleeting openings, which are probably far more common than people expect on 10m. Remember, the F2  or transequatorial propagation has only to go above 28.126MHz for 120 seconds and someone on WSPR may spot it!

Motion sensing using the doppler effect
In order to measure the doppler effect for motion detection on a conventional computer, what you can do is send out a sinusoid at some known (inaudible) frequency, say, 20 kHz.
