I suspect that, overall, very few hams actually take the time to read ham radio blogs. Of those that do, there is probably only a small percentage that take the time to read any post-blog 'comments' that might be made by others....so...if you missed the comments regarding my recent e-Bay resistor purchase, the following information may be of interest.

Steve, G1KQH, commented that he had found an even better deal on resistors from China at Banggood, in Guangzhou. I have heard good things about this company, which sells a large variety of items from electronic parts to the latest quadcopters. Steve reported a good buy on 1%, 1/4W resistors...50 different values and 50 of each....2500 resistors in total. The offering may be found here.

Steve adds: "The values of resistor are: 10M ,4,7M, 2M, 1M, 390K, 330K, 300K, 220K, 200K, 180K, 150K, 100K, 82K, 68K, 47K, 33K, 37K, 20K, 18K, 15K, 10K, 9K1, 8K2, 6K8, 5K6, 4K3, 3K9, 3K3, 3K, 2K7, 2K4, 2K, 1K5, 1K2, 1K, 680R, 470R, 300R, 270R, 180R, 91R, 68R, 56R, 47R, 20R, 10R, 6,6R, 1,8R, 1,2R , 1R.
They are five banded resistors inc one for the tolerance.
Arrived quick and you can use Paypal on Banggood, so no problem getting your money back if things go wrong."

With the free shipping, this is a super price and could be very difficult to beat! In addition, they offer smaller 1/4W resistor kits, a nice kit of 1/2W resistors, SMD kits and capacitor kits.

G1KQH maintains an interesting amateur radio blog, well worth a read. Thanks for the info Steve.

I received an email this morning from ML&S, that they are moving their Chertsey store to bigger premises in the New Year:

A fire has destroyed the manufacturing facility of Hardened Power Systems, a research, design and fabrication facility in middle Tennessee. Popular among radio amateurs for their portable power hardware the DHAP, and other unique equipment. Current orders destroyed, but owner Bill Harrison says they will be back.

In this fortnight’s episode of Linux in the Ham Shack, Pete (VE2XPL), returns to the land of the living. Your intrepid hosts discuss explosions in the sky, a “holiday” for ham radio operators, Linux vulnerabilities, caipirinhas, and ask the vital question: What is Allstar Link and does anyone use it? All that and more in this action-packed installment of LHS. Thanks for watching, and as always…

Jay has been working on new versions of his little WSPR beacons. All being well I should receive a 10m 500mW out version in the next few weeks.

Jay is writing the manual(s) and has asked me for my feedback, which I shall, of course, provide. The new version is a single board (again) but transmits continuously, randomising the TX frequency on each TX burst to minimise interference to/from others. It needs several minutes to thermally stabilise but uses the uP to generate everything needed such as the WSPR tones, so no PC is needed. The transmission is started manually on the start of an even minute with a push button. The PA can be separately enabled.

This should be fun. I’ll give more information when it arrives and I get a chance to try it on the air.

Some years ago I went to a BBQ where someone had a wi-fi controlled quadcopter remotely controlled from an iPad. It was very impressive with its on-board cameras for navigation and filming what was happening down below.

I see AE5X has a video showing the inspection of his antennas (from above) using one of these. My antenna farm is trivial by comparison and can be pretty well examined at ground level.
