The Tenbox may not get finished until the New Year now as we have family here for the next 10 days more or less. When there are 4 grandchildren around, amateur radio takes a back seat, especially as my operating shack is used as a bedroom for the 3 and 5 year olds.

Tenbox 10m AM crystal
Although I've not finished off the Tenbox 10m AM transceiver yet- too cold in the workshop and too many Christmas preparations! - I have been looking around for some low cost crystals that would be suitable for the transmitter. Ideally, I was looking for a low cost source of HC49 crystals on 29.05MHz but have not found any. Then I spotted that the German QRP-shop has 29.000MHz crystals at a reasonable 5.5 euros. I may order a couple so I can complete a pair of QRP 10m AM transceivers. I have used QRP-shop before and they give good service.

Designing crystal oscillators
If you want a range "sure fire" crystal oscillator designs to suit fundamental and various overtone modes you should check out the "Oscillators" page on the QuartSLab website. This has details of circuit values and configurations that will really work. Most of these designs are ones I recognise from my days at Pye/Philips PMR, so I know they are reliable and well tried.
