My HF vertical, veteran of GB6VMR had developed a severe wobble, the insulator on the feed point had failed. It was only a piece of tube with a liner and was riveted together. Over time the rivets had loosened and the tubing had cracked. Drastic repair was needed - there's nothing similar on the market at the moment, and as this was one with a raised radial kit, certainly not at a reasonable price.

Oh well, one to clock up.
Yes it's felt like a long haul so far this year.
The long haul has been up and down to the VHF Contesting location of course. The precise location is kept a trade secret to all but the select few such as G4RLQ (hardly as he lives about a mile away). It does lurk at about 273m ASL, and has a very good view to the south and east, where it appears most of the likely contacts are located.
Yes finally, we did it. A steam rally, just the place for steam powered radio.
No we didn't have as much room as previously experienced at the Vintage Machinery Rally, so the antenna situation was less than ideal. The VHF antenna worked very well, but hanging the 80m loaded dipole didn't work and we had problems getting out. I suspect that most of the RF was going to warm the ground.
The weather wasn't too good on Saturday, but the awning kept the rain off us and the tea kept flowing. The Flea Market brought me a nice gas lantern of fairly epic output.

QRP-labs.com offer a range of cost effective electronics kits for radio hams. I chose to order and build their 20W Dummy Load kit.
The kit is simple to build, consisting of x20 1KΩ 1W resistors sandwiched between two PCBs with a BNC connector. There is also a diode/capacitor circuit for detecting the peak voltage, if required.
