Hi Steve, Lowfers, It's something I might do once I've retired and have the time to search out the required components, as my QTH is in the "electronic boonies" of Ontario. The closest supplier/store is London, so it's that or order online. 73, J.B., VE3EAR LowFER Beacon "EAR" 188.830 kHz. QRSS30 EN93dr
