136kHz QRSS3

My big project for the week (this would have been trivial a few years ago) will be to rebuild my E-field probe for 136kHz and do a fairly local test with it on the car roof on QRSS3. I have the TX beacon, although it has not been used for over 2 years and never from this QTH. I think I have the RX bits somewhere but need to find these first!  For the TX antenna I am going to use my earth-electrodes which will need rematching for 136kHz.
