I agree--20 WPM a good working speed so the crashes don't wipe out the dits. Even a little slower might be best. S9SS runs slower, and makes LOTS of SOLID contacts where one knows if the contact is "

Problem here is that there is NO guarantee that whats right for sending TO the DX is best for COPY of the DX. The conditions can vary so much from one end of the path to the other that It might well

My two cents: I support beacons for a different reason. Every ham sitting listening to a beacon is one less that will clobber me when I call the DX! It seems to me that beacons on VHF, or even HF, ma

I have found that my Rx verts suffer considerably from being "hillside mounted". However, there does seem to be some advantage in some directions where the verts are blocked from noise sources. I thi

I believe that is called "wetting" the contacts. You'll need either RF chokes or perhaps--if you used higher voltages--you could use resistors chosen to get a few ma of current. Memory tells me it do

Another comment. Make sure you NEED a preamp. If everything is well matched and you have controlled any leakage into the system by decoupling, grounding, etc. you may find that you actually have enou

You'll find a apir or so of Inverted L antennas with a good ground system pretty hard to beat as a start. The ground you put in, if you plan ahead a bit, will last for future antennas. Get as much ve

To answer your question you need to measure the character of your antenna with considerable precision. Based upon what you describe, there will probably be very little difference between the two setu

In my experience anything that you can do that prevents noise from being conducted thru the wires in the area of your antennas will help you to hear weak signals in some case some time. Thus, it is m

It seems to me that the 160 bandplan needs a bit of study. While my observations may be off, it seems that the space above 1900 gets very little regular use. Perhaps a 10Khz non-dx cw segment?? The p

I too must make remarks. Topband WAS during this contest would have been very hard from here--I felt the band was rather flat and the general noise level was high. As to "how" easy 160 WAS can be, it

In my experience, inverted L and Vert antennas are often full of noise because of a "ground loop" (for want of a better term) between the local power company neutral and the antenna ground system. Th
