The QSO-per-hour rate is not I he problem. The problem is that while such an operation is in process, all normal dayto day communications come to an abrupt halt. This hardly endears us to our fellow hams. While a few wrote to say that all split-frequency operations should be banned (transceiver owners, no doubt), the majority favored spreading the calling stations out over no more than 15 to 20 kHz. If this proves inadequate, the DX station can go by call areas or even by prefixes...

With pre cut and prebent leads, You won't be pushing diodes with plier-nicked leads or the wrong spread into the sockets, damaging the contacts. For this reason, if the 50 diodes supplied aren't enough (unlikely), 1 recommend ordering the extras from Drake. Since the extra offsets beyond the standard ones are set up on a diode board, elimination of diodes would require the oddball offsets to be set up with switches on the front panel. That wouldn't be a bad idea, anyway. The power connector is...
