Hi Mike et al, BOGs have a well deserved reputation for being cantankerous, with great results for K4ABCD over here and awful results for K3WXYZ over there. There is a part of the explanation for tha
160 is coming back from 2, maybe 3 weeks of doldrums and not making it over the Sierras, or tickling Europe. RBN's tickled from CWT on 160 2345 to 0000 Wednesday night local Hits to the east: OL7M Hi
Hi, Gary. It is not clear from your description exactly how the "sloper" is fed, where the radials are in relation to the tower, etc. Quite a few things could be responsible for a change like that. N
The referenced Ameritron/MFJ part number is an 11 inch coil (aka BMW coil stock of old), coil wound into 4 polystyrene rods. This one is 3 inches diameter, four turns per inch, 10 AWG tinned bare sol
Hi Rick, Wes, I said it was a "killer piece of copper". I did not compare it to anything. Mostly I like the way that edge-wound coil looks (what was on my mind when I said "killer") The same way I li
Hi, Ed, Taking the vertical wire up next to the tree trunk will be fairly lossy. That usually also means that some part of the horizontal wire is going through the tree canopy, which will be further
Essential point that might be missed: each one of the elements, one at a time, must be tuned independently with the other three elements down. This is the initial tuning. If when everything hooked up
Hi Mike, For elevated 1/4 wave radials to work well, they need to be carrying the same RF current away from the common center point. This is to produce near net zero RF fields at the ground. 1/8 wave
I sometimes get around to posting on these things only when I'm not buried by something else. So late as this may be... I'm sure that the writer truly meant "worked very well", but that is not a scal
Hi, Julio, Sorry for delay. I didn't see this post when it hit the reflector. Around 2009 before publishing the FCP design, the change to polyimide coated wire and Teflon sleeve brought a string of t
Quite late in response, partly done much earlier. Sometimes I have time, and sometimes I have a house and a spouse. Peter's original question in this thread was why a radial and mesh mix in a counter
Went looking for them after finishing the 0300Z CWT on 160m. He was down the band some from where the CWT mob had been. I had seen somewhere that they were working up 2. Called him once up about 2 an
Hi, David, Regarding the FCP 160-80 meter dual banding project and circuit component sizing particulars ... I completely understand the urge to downsize. However, the devil is in the blasted details.
Hi Mike, You certainly are not the first to experience an antenna "grounding" that makes unbelievable the contacts actually made with it. BTDT for sure Another thing is our common predilection for th
Have to remember that W8JI, ON4UN and many others were not lying or deceived. What we are finding out is that a major rule has some exceptions. If you're talking to a club member in the US, you bette
Hi Kenny, You set your curiosity on a real toughie. Tread where angels fear to go, and all that. The N4KG feed is extremely situational in its efficiency, or some efficiency, or no efficiency. It can
Hi Terry. Whatever you are referring to didnt make it through the reflector. Can you provide us with a URL link to the connectors? Thanks and 73, Guy K2AV -- Sent via Gmail Mobile on my iPhone ______
I agree with Rick, If an N connector is not designed to fix the relationship of the center pin (soldered to the center conductor) to the body it should not be used outdoors or on long runs of unburie
Hi Chet, Before we start, a disclaimer: I still have my MP, maybe I'm a radio hoarder. I do have a 75A3 and a Johnson Ranger and Courier and an FT 101ZD. The only long used radios I don't still have
Apologies to all for delay in response. Losses related to ground and close dielectric materials remain the single monster gorilla in the room for improving TX performance of vertical antennas. Settin
