All those kinds of rigs with parallel BS170 PAs are sensitive to VSWR excursions. The absolute worst thing you can do is tweak an ATU with the rig at full power. Either use an attenuator (e.g QRPOMETER) or reduce the rig supply voltage to tune up and then increase the supply voltage once tuned.

My QMX has been fine, I haven't tripped the SWR protection with the latest firmwares - I think the default was put up to 3:1. I run either a home made dipole or home made 7MHz EFHW on 40m and 20m.

Great to catch up with Trainee Search Dog Jura at Kendal Mountain Festival today. It was meeting Jura last year that inspired me to volunteer with my local MRSDE group as a 'body'.

This Traveller was good only for scrap or total rebuild. The original engine did come back to life with a replacement cylinder head which happened to be laying around. The engine was sold for project funds.

It's not stupid fast, but it can keep up with modern traffic. With the six speed box it cruises on the motorway with ease. Yes, the brakes are good and the mass is low anyway.

Yeah, a little bit more up to date to make it usable. I tripped the engine management light yesterday, looks like we'll have to plug into the OBD port again.

No need for a key, no clockwork in this Moggy. 1.8l VVC twin cam provides the go.

AA batteries are generally a poor power source, but they'd probably work to some extent. A lipo battery and charger would be a good investment and needn't cost an arm and a leg.

This is my second one. This time I went for 60-15m as I want the option of 40m SSB. Last time I got a 20-10m version but I don't use 10m! I didn't want to risk re-working a perfectly functional rig, so I bought another.

Really enjoyed the series, just a bit sad that there aren't more episodes! Particularly enjoyed the bits about Atlantis as I witnessed the STS-112 launch from Cocoa Beach, and then later went to the press launch of an IMAX film, presented by the whole STS-112 crew.

Last year I was weighing my t-shirts and buying titanium cookware, trying to get my all up bike weight below 115kg for my bike tour trip. 115kg is the stated bike+rider weight in the Cube handbook. I've just found out that the 25kg rear carrier load isn't counted in that! Gross weight is 140kg. Doh!
