Topband: Another good LP day on Top
The December Doldrums are officially over. For the second day we had good long path/skewed path conditions in the pre-dawn hours. This morning's excitement started with VK3IO (579) calling in at 1018z and VK3ZL (599!) at 1037z. Often when the VK's are this loud it's a sign the band will be poor to the tougher paths in Asia and the Pacific, so I didn't get my hopes up. But then KH2/N2NL came through nicely on the direct path at 1100z. And a few minutes later, Hiro, DU1/JJ5GMJ, showed up on 1811.5 and was being heard in New England. And I could copy him here in Delaware! DU has been a long, hard chase for me, having heard my first (a US station portable there) around 1980 when I was in Connecticut. I heard a few others over the years, including a 5-year pursuit of DU9/N0NM, who I heard many, many times with no QSO. And I've heard DU1IST both in our morning and LP in the evening the past two years. But unlike some of the others, Hiro manages to hear stations quite well. And his 300 watts and inverted L put out a good signal. I was fortunate to get him in the log at 1110z (no. 314) and numerous others also had success. Thanks Hiro for your persistence! About this time BU2AQ also started coming through, peaking due south though later shifting sometimes to SSW. I was copying him up till 1200z. No prize for me today but Allison did work several East Coast stations. DU1IST also started CQ'ing, and while his signal was stronger than Hiro's, he has difficulty hearing and no QSO's were observed though he had many callers from the USA East Coast. Peter, XU7ACY, has had a strong signal here on the long path the past two days, and he gave many a new one today. Ross, 9M2AX, also was coming through again today but had some trouble with local thunderstorms there. In other years with these long and skewed path openings, as sunrise approached the Asian signals often would shift around to the short path.

Re: Topband: Galvanized Beverage antenna wire inquiry
Any series resistance or inductance will slow the incoming wave down and increase the tilt and the length where it reverses direction can be calculated since a 50% VF is the crossover point. A Beverage by definition is a slow wave antenna. I use 2 types of military telephone wire for 5 reversible 2 wire Beverages. One is a copper/cadmium alloy and the other Im not sure but its the common WD-11A that many use. At 500-900' they seem to be no different than predicted. I find 60dB nulls a bit of a stretch on a regular basis on any sky wave signal. Some here may have hit 40 on a fluke but 20-25dB seems average and with some a bit worse.

Interlocked switches should not be necessary for receive applications. If by interlocked you're looking for a way to deselect one antenna when selecting the next, check K1TTT's web site.

The primary need for selection of RX antennas on TopBand is to be able to switch from any one to any other instantly without the tedium and confusion of having to spin a rotary switch back and forth whilst trying to find best copy out of an extreemly weak signal down in the noise. A matrix of quiet interlocked push button switches would be ideal, which require just one push to instantly change from any one antenna to any other. Unfortunately, they're not easy to come by these days which is why I'm thinking of a relay based solution.
