If you like DXing the broadcast band, then the weekly ‘DX Central MW Frequency Challenge' may be of interest to you. It’s run and organized by Loyd Van Horn, W4LVH, a dedicated DXer and a big promoter of BCB DXing.

Basically, participants are asked to listen on the chosen frequency for a one week period and report what they have been able to identify. Results of course will be different throughout the continent but if you are near any other listeners, it’s always fun to compare your final results.

The new frequency (or frequencies) are announced Sunday evening around 0100Z on Loyd's regular live-feed Youtube channel as well as on his Twitter feed   @dxcentral 

Loggings are reported via a fill-in form which is updated weekly.

As well, information on most aspects of AM BCB DXing can be found on Loyd’s website.

Hopefully you can give it a shot during the week and see what you can catch. 

 

                               This week’s frequency is 1450 kHz.

As I have blogged in the past I have been taking part in the CWops mini weekly contests. It gives me some nice practice for an hour. Things have been going very well using N1MM+ contest software. Until my last CWops contest. N1MM+ uses macros to send your call and the contest exchange, you just push the key for the designated macro and you are off to the races. Well up until my last contest this was how it was working....then not so much.
I pressed the key to send my exchange, the Icom 7610 went into transmit and N1MM+ sent "Mike NB" (my name and province) BUT this time the radio got locked in a transmit loop and sent the exchange over and over. The only way to stop it was to turn the power off on the radio. I was not sure if it was a software glitch with N1MM or what. I continued and the issue did not come back...well for a little while that is. This time I sent my call sign and it was locked in a transmit loop!
When these anomalies happen I always try to look back at what I had changed since the last time it was working just fine. The first thing that came to mind was just before the contest I updated N1MM, so I loaded a previous version. (always keep them in a desktop folder for the just in case moment) I then went back into the contest and within short time it happened again with a transmit loop.
There were no other changes that were made so instead of using the macros in N1MM I sent using my Key....old-style contesting. Doing this I had no issues at all so then I used my wireless keyboard. There was no issues using that so next, I used my old USB keyboard. and no issues with that.
Things are narrowing down to my Lenovo pro 2 keyboard as the issue. Since the issue only happens during transmit I am guessing it's an RF issue with the keyboard. I had some spare rf chokes and I placed them at the USB connector end of the keyboard and that did the trick. Funny thing I had been using this keyboard for over 2 weeks in contests without issue. But that is how RF works and I am glad that I am still able to use my Lenovo keyboard and have no more issues.

20m at 19:10 during the CWops 1 hour contest

 

With the increase in sunspots and rising flux comes some solar flares and the Kp-index will have it's ups and downs. This afternoon the Kp index up was up to 5 and 6 and that does not my Mike the ham a happy person. Now having said that right in the middle of the high Kp index the bands at 19:00 UTC came alive! It was the weekly running of the CWops test, a one hour contest. Before the contest 20m was dead and at 1900 UTC life was brought to the band. Stations from Canada, U.S and Europe warmed up 20 meters to a nice glow. It's great mini contests like these happen as it shows some action on the bands. 

Another great CW contest is the K1USN SST CW contest this contest happens on Fridays at 20:00-21:00 UTC and Monday 00:00-01:00 ( which for most of us is still Sunday evening) This contest is not one of speed but slower. You will find operators sending from 10 wpm to 20 wpm and if you are not sending at 10 wpm then speed is slowed to match your speed. These are nice contests that only asks for 1 hour a week and it can get  your feet wet with contesting.
