I have a JK 404C side mounted to a Rohn 45 tower. It is currently fixed on EU. It works great but now I want to rotate it. However, its weight (170 lbs) limits my choices. The new TIC rings are not a
Wow. This is the first time I've posted here and I'm blown away by the number and quality of the responses. Some more detail... The 404C sits just above a star guy bracket with three sets of Phillyst
All: First, many thanks again for all of the great responses. As a result, my way forward at this time is the swinging gate solution. The IDC Technology "Sidewinder" is at the top of the list. It see
Is anyone here using ChatGPT in the context of amateur radio? Potential use cases would be design of antennas and tower installations, software code generation, problem solving, etc. If so, what do y
I have a dead G1000 rotor controller. Push power button - nothing. Any suggestions as to where to look for a fix? Tnx &73 John NN1SS _______________________________________________ __________________
Something that has confused me since I started using this amp two months ago is the fact that it has two power switches - one on the rear panel of the amp and one on the remote control pod. The manua

I would like to suggest that there may be broader implications. On any given day, more than 80% of all activity on the HF bands is in the digital modes and largely in FT8. Look at RBN spot data that

All: As John/KK9A has pointed out, I was originally responding to the shutdown of MFJ because the supposed demise of ham radio is something I've been thinking about for a while - ever since a manufac

All I'm trying to post a picture of the swinging gate installed here that turns a JK 404C but the list won't allow posting the picture. Please email me if you want the picture. I also have the same s
FWIW I have two C31JK-XR tribanders - one at 90', the other at 55' - fed via a DXE phasing box (U/L/BIP/BOP). The lower C31 is on a swinging gate that rotates from 350 degrees and around through 0 de
All: I put up a pair of phased verticals for 80 on the slope of a hill. The verticals are wire supported by 60' spiderbeam poles. I picked a spot where the antenna bases were as level as possible but
I do the same. But I also do a final wrap with white Scotch 88. This reflects sunlight. Black coax seal (and anything else black) can get very hot in the summer and change. 73 John NN1SS ____________
Yes. Scotch 33. I typically find it at hardware stores or the big box home improvement stores in the same place where they keep the Scotch 88. The point is to reduce the heat that could transfer to u
