I think the future of radio hardware is a piece of wire connected to a GPIO pin. The rest of the radio will be “gcc compilable” free software running on commodity CPU horsepower.

BCB DX – Two New States

With the recent quieting of the geomagnetic field, resulting in K values of 0's and 1's, along with a positive-going DST value, the broadcast band on Wednesday and Thursday night was much more vibrant than it has been in several weeks.

Being located on the eastern shoreline of Mayne Island, the direction towards all of the U.S.A. is over many miles of saltwater, so my main interest is in domestic / U.S.A. DX.

Wednesday evening netted two new states on the BCB ... Kansas and Indiana, for states #27 and #28 respectively, both heard on the Perseus SDR and my 10' x 20' amplified loop.

KWOD, on 1660KHz, identifying as "The Business Channel", was logged during a short top-of-the-hour fade-up at 0600z (10PM local time). Their night power is listed as 1,000 watts while their day power is 10,000 watts.

The transmitter site is located in the middle of a quiet residential district of older homes ... on all four sides.

I shudder to think what RFI problems those living in the adjacent homes must suffer when they are on daytime power!

WSLM, on 1220KHz, was also logged at 0600z, during a two-minute fade-up and in the middle of the local weather report.



Interestingly, the station's night-power is listed as "82 watts", which, judging by the readability of their signal, was not the case. Perhaps the engineer just 'forgot' to switch from their daylight power of 5,000 watts!

Their phased antenna array puts their main lobes, due east and west, so evidently I was catching the northern edge of their pattern.

See what you can hear their during the short recording made of  the "Country WSLM" weather report





I have yet to check last night's recordings to see if conditions have held-up for two night's running ... more later if so.

Frog 40m transceiver

This is the Pixie’s “big brother”. I have mentioned it before in this blog. It has more power than the Pixie and a better RX. Best of all it costs just over £15 built with free shipping from Hong Kong.

40m Pixie

Yesterday I found my rechargeable 12V battery and charged it up. I also checked the Pixie I built as a kit for dry joints and shorts. As all looks good, I hope to test this on the air over the weekend or early next week.

There are a couple of locals I’d like to test with initially, although I am expecting to suffer from AM breakthrough mainly from broadcast stations very close to our 40m band. Probably there would be less breakthrough in the daytime? My antenna is short and low on 40m (a Par triband end-fed covering 10m/20m/40m) so any contacts will be good!

I can test it first on a signal generator and then a power meter. If it works, I’d expect a sensitivity of around -100dBm and a power out of around 200mW on 40m. We’ll see. Even -80dBm and 100mW would be enough to work locals as long as AM breakthrough is at a manageable level.

Cale, KK4HSX

I began reading Cale’s (KK4HSX) newsletter a few weeks ago and was impressed by its style and organization. He does a tremendous job curating some of the best articles and posts from the week and puts them into his newsletter. I think you’ll find he has a real knack for finding the interesting stuff that might not otherwise make it onto your radar — without having to wade through lists of endless links.

If you’re already a subscriber to our daily Amateur Radio Newsletter, we’ll include a link each week to a post featuring the latest issue of Amateur Radio Weekly so you won’t miss it. You can also subscribe directly to his weekly e-mail newsletter by clicking here.

Thank you, Cale! We’re excited to read what you discover!

TSM Reviews: Teak Publishing’s 2015 Air Show Guide

Here’s a review of his latest Air Show Guide.

When Good Caps Go Bad

I’ve been helping out the guys in Springfield, IL get the W9DUA DSTAR gateway back up and running. We were successful reviving it after some Linux magic and Google-foo I performed a few weeks ago. We did notice that the server would reboot occasionally. Weird, but hey this is amateur radio not public safety.

After a few more hiccups it was time to investigate. Steve, K9CZ brought the server to me to take a closer look. After putting it on the bench and doing some more testing, I got to the point where I could scare it into a reboot on demand. Nothing in the logs, memory was properly seated, Dell diagnostics all passed, and reverting the last OS patch didn’t help.

Hmmm….looking around some more…I found these four capacitors on this Dell SC440 motherboard. Yep, they are toast. Something bad has happened in this server’s past. I yanked the hard drive and have it in a new machine now…after some more testing it should be back up and running by the weekend.

When capacitors go bad, bad things happen.
