Topband: Conditions on 160m for ARRL Contest

[terry burge]

I listened a bit on 40 and 80 mtrs last night and the night before on SSB. I thought conditions were practically non-existent on 80 especially.  40 wasn't much better. Turned the radio off again and worked on other things. Don't exactly see any reason for it on the propagation page since the sunspots have been at least a bit active (26,20,18, 15,12). Hoping for better conditions this coming weekend during the SSB contest on 160. I know that FT8 activity is likely to get some qrm around 1842 KHz.


All this talk about inv-L's has got me wondering about adding a second one longer than my '1/4WL' one. But being so cold and the possibility of messing of the operation of what I have now has kept me from trying a longer inv-L. That and not being sure exactly how much and how high of voltage a variable capacitor I would need. I do have some 500pF 10KV doorknob cap I can parallel a variable cap with. And now hearing I might need longer radials. An acres and a half only allows only about one 160 meter antenna at a time along with my other ones.


But the talk has me thinking.
