I agree with Mike that it is usable on 136 with a bit of assistance, but not on the lower band. Not hearing much on one band and *!*!*! all in the other, I decided to do a proper test. If anyone is interested, the CW 10dB S+N/N in the narrow filter (270Hz) checked using a TF2008 sig.gen. (admittedly not recently calibrated but within a dB or so against a known source) at the two frequencies was - 136 KHz 10uV p.d. 73 KHz 83uV p.d. Now unless I happen to have a particularly dud sample, it would seem that there is a pretty good HPF in there. Due to circumstances beyond my control (building works to provide a 'boys dorm' for visiting grandsons and a home for the dispossessed shack/computer suite/workshop in a new 'west wing') it will be at least November before regular transmissions can be made on LF, but I do intend to keep the promise I made earlier this year. The only good thing to come out of all the excavation and general flapdoodle is that I got a five leg earth mat down under the founds of the extension. 73 de, Ian
