Concentrating on one or two bands?
With limited space for antennas, it seems sensible to concentrate efforts on just a couple of bands only. As my favorite band is 10m, I am tempted to erect a more efficient antenna for this band and maybe put up the 6m V2000 only during the Es season. My problems are (a) a lack of mobility because of my stroke and (b) choice of compact, efficient antennas. At present I can cover 40, 20, 10, 6, 2 and 70cms, plus 630m rather inefficiently with my earth electrode antenna. Perhaps, whilst my health is not too good, I am better sticking with what I’ve got? I know that on 10m my antenna could be better but the Par end-fed covers 3 bands (10, 20 and 40m) and my 2W QRP has reached VK on WSPR on all these bands and doesn’t do a bad job.The Par is is almost impossible to see in the air.

CWT Mini-Contest – QRP Style
In my continuing effort to evaluate my attic dipole, several guys have given me advice to get on during a contest because the activity level is higher on the bands and I could better evaluate what I can hear.
Every Wednesday (local) evening from 0300-0400Z (Thursday) the CW Operators Club has a mini-contest the call CWT. The exchange is name and member number or name and state if a non-member.
These guys are serious CW operators, and I knew the pace would be fast. I downloaded N1MM for logging as they have a dedicated module for the contest. They also have a call history file that you can load which allows you to enter the call and it matches the name and member number up for you.
So I had everything setup and ready. I started on 20 meters and heard some activity. I made one contact there before heading to 40 meters.
On 40 meters the band was filled with signals – this warmed my heart after my recent worries with my antenna!
CW was being sent very fast – but after several listens I could usually get the call. I just looked at the scores here http://3830scores.com/currecscores.php?arg=JxfqcDz6ficvT – I ended up last in the QRP category, but NOT last in the contest!
I ended the night with 6 QSO’s during the hour long contest. Honestly, I am happy with those results. My goal was 10 contacts, but I learned some valuable lessons which will help me next time!
Here is the list of my contacts (all CW Ops Members):
K1BG Bruce 20M – MA
N1LN Bruce 40M – NC
KC4D Bill 40M – VA
N5ZO Marko 40M – CA
AD4EB Jim 40M – TN
N5AW Marv 40M – TX
So I worked 6 different states – MA, NC, VA, CA, TN, TX – coast to coast!
Thanks to those that pulled my QRP signal out! I will be back to this contest in the future!

6m GDX tonight
No Es here on 6m WSPR since I QSYed to 6m around 1500z. There has been some GDX again, G8JNJ/A (184km) was spotting me at -24dB S/N at 2128z. Doppler was low suggesting tropo without aircraft reflections, or aircraft crossing the path at right angles (so little/no Doppler).
Again I am bitterly disappointed with the lack if USA/Canadian east coast stations on WSPR. As of 2145z there were still ZERO stations active on WSPR from that area. Come on lads! Give we Europeans a chance of being spotted over there!
Unless there is some interest from the east coast USA/Canada on WSPR very soon it will be time to abandon 6m WSPR this season. I have been spotted all over Europe, in N.Africa and in Israel (3519km) with just 1W ERP in the last few months. I was hoping for the USA or Canada on WSPR this season. If there are zero stations at the other side there is no point in continuing.

New Chinese multi-mode HF rig – Xiegu X108
Steve, G1KQH has sent this link about a new Chinese multi-mode transceiver. See http://www.brickolore.com/ . Prices start at 2800 Yuan apparently. It is called the Xiegu X108. There is a video and some pictures of the rig.
To my mind, this still looks like a “back shed” radio, rather than a mature, well engineered and thoroughly well tested radio. I may be wrong. I am still waiting to see when the Chinese launch a proper Yaesu or Icom competitor. These will come but I’ve not seen one yet. Maybe in the next 12 months?

Great amateur radio-related technical explanation videos
While searching for an informational video about exactly how parasitic antenna elements work, I found a treasure trove of ham and electronics videos made by Stan Gibilisco, W1GV. There’s a lot of good information here and his YouTube channel is worth a bookmark.

Finished work on the TYT TH-9800 quadbander review for Practical Wireless
I’ve had a review model of the TYT TH-9800 quadbander (28/50/144/433MHz) around for a little while, to do a review for Practical Wireless and over the last few days, I’ve wrapped the review up.
Clearly, I can’t give too much away here – the review will be in the next issue of PW – but it’s fair to say that the rig worked out well. As regular readers will know, I’ve had a Yaesu FT-8900 for a few years now. The TH-9800 follows that pattern very closely and works well (though is not identical). Well worth a look if you’re in the market for an FM quadbander. I’ll be sorry to send it back!

The One Frequency You Should Never Use on Field Day
At the local radio club meeting, I encouraged everyone to get on the air during Field Day, which led to this conversation:
New Tech: I just have a 2 meter fm radio. Can I still make Field Day contacts?
Me: Sure, VHF contacts are encouraged during Field Day.
New Tech: So I just call on 146.52 MHz and see who’s out there?
Me: Well, no, the 2m fm calling frequency is not allowed for Field Day.
New Tech: Really? We can’t use any of the calling frequencies we learned during our license class?
Me: Well, no, all of the other standard calling frequencies are fine, just 146.52 MHz is prohibited.
New Tech: That seems really dumb.
Me: No comment.
