CQWW used to have the Xtreme category that allowed/encouraged remote internet stations. Seems like that's the place for those who want to use remote receivers. I haven't kept up with that category bu
Tom, W8JI, has some good info on the proper use of silicone grease on his website: www.w8ji.com/dielectric_grease_vs_conductive_grease.htm Kris N5KM O-rings are good. :-) However, even if we use good
I use the MFJ-1025 (similar to the NCC-1) with my SAL-20. In my case I use my TX antenna as the sense input. My xcvr (FTdx5000) internally feeds the TX antenna to an output connector while in receive
I, too, have to agree with Larry, K5RK. From my location in NTX in a noisy urban area I struggle to hear any 160m DX (using an SAL-20 RX antenna). Last week there was a thread about a "Huge NA-EU ope
I was just lamenting in my last post that I hadn't worked any DX on 160m this season. Then this morning the propagation spotlight shown on N TX. Incredibly strong signals from Asia. JD1BMH, HL5IVL an
I know that fading can be caused by phase rotation of the arriving signal. Can fading be caused by the signal changing arrival angle over time (1-3 seconds)? I ask this because of something I observe
Which brings to mind another issue: 160m card checkers will disallow a card if the DX QSO occurred in the middle of the day since the path would be impossible. Can't make that assumption, anymore. Kr
JC, The shielded 50 ohm load is placed at the RX antenna feedpoint or at the radio's RX input? Kris N5KM -- original message -- Date: Thu, 24 Mar 2016 08:14:35 -0400 From: "JC" <n4is@comcast.net> To:
VOACAP and other propagation forecast tools provide shortpath and longpath predictions. However, at my sunrise I'd like to know the greyline path prediction. For instance, SouthWest to Asia (from Tex
Hi Carl, Well, I guess I was cheating a bit by posting here. I was hoping the folks who dwell here might be more knowledgeable about propagation than other forums. (You prove my case. Hi.) I've been
Hi Thomas, You've provided quite a wealth of information. I will study it to try to understand. For the past several years I've been collecting some lowband propagation data as well as stations heard
Hi Jim, I made a few of the RX chokes from your Chokes and Isolation Transformers for Receiving Antennas paper using CAT5 twisted pair. Why is it that these RX chokes are OK with twisted wires while
