LF It now takes hundreds of watts to be observed or heard around EU on 137 Khz whereas some years back less than 200 watts achieved a good result like a QSO on CW. The 130 watt Ropex used by many res

LF Well it seems some are of the opinion that the problem is not Antennas but increased environmental noise and Seasonal conditions. Others say that a small antenna for RX es Grabbers is better than

Hi Mal and others, It would be interesting to know if their reports of other Txs have changed over the same time. In other words, is it a change in their sensitivity (whether due to Ae change, pre-am

Mal, Most grabbers do not use the main antenna, I have only one main antenna for LF & MF so the grabber uses an active antenna which has got to be better than none, therefore no grabber. 73 Gary - G4
