I know I worked you in some of the next few contests. I don't have the logs any more, so I cant look up what really happened. I think I made something like 40 contacts. What I clearly remember was be
If you try this (good) approach, be SURE you get a PASSIVE video switch. You do NOT want video class distribution amplifiers in the path from your beverages, noise, overload, etc. will kill you. If t
I like your definite answer: It Depends! Truly! It unfortunately seems a bit complex to make a rule other than build it and see! Your experiences match what I would expect, but there seems to be more
And if you cant work Dietmar, you sure aren't going to work anybody else within 5000 Km. He can dig out and work stuff I can just sorta barely hear listening with my headphones in parallel with his!
Maybe this is a good time to share the techniques we individually find successful for hearing through the giant sparks. Directional receive antennas, obviously, Receiver AGC? IF bandwidth? IF and RF
not to belabor the point excessively, but.... when I was sailing up from ZL on Braveheart headed to Mangareva on the way to VP6DX, I listened to the Friday night beginning of the CQ160CW contest. I h
an experiment to see if a couple of photos will make it through- I shrunk them to be small enough that they might be tolerated - but I suspect they will be stripped off these are two of the fish beac

I seriously doubt it - check the links - they all seem to be crystal based. There are "smart" beacons that respond only when interrogated by the owning vessel. Nowhere is there any indication that th
In the trip across the south pacific from ZL to VP6DX, we were about in the middle when the CQWW160 CW contest started. ( I was the only expedition member aboard at that pointwe were bound for Mangar
wont waste bandwidth recapping in any detail but they are a C H E A P crystal controlled "MOPA" with a 6-8 meter long whip. the ID runs on a cycle like Merv says. The beacons have something like 36 D

ALL of the 10 KHz frequencies are bad somewhere in NA, and the same issues apply to the 9 KHz spaced MW stations in other parts of the world. Second harmonic, and regular ordered products abound. Exa
an added note/comment here During the XZ0A expedition, I think we conclusively proved that: 1: Skew paths exist and are repeatable 2: the arrival angle of the signals is NOT reciprocal. The arrival a
I have a mostly similar background and experience, 2way radio and silicone grease, except, they learned. At 400 mhz and higher, flooding an N connector with silicone greade (dow #4) introduces a
Towers less than 200 ft are not painted except in specific unusual cases.If someone bought surplus tower sections that are painted, unless the tower is a special case, just let the paint fade and do
And that period at and after sunrise is MUCH quieter considering that more than half of the directions for propagated noise sources have been reduced or eliminated. Depending on where you are that re
Milt Jensen, N5IA (SK) constructed his original (circa 1990s) 160M station TX antenna based on a similar design I encouraged him use. He built a 180 ft tower with an insulator at 50 ft, Four elevated
I operated 160 CW mobile - back when the band was segmented. I did it in a VW beetle with a tank whip mount and the whip cut with an insulator and a big loading coil. and a straight key 6 Volt system
I worked KH6DX in his mobile -- as I recall he was /W6 -- from XZ1N. 1998 or 1999 Its on tape - somewhere. I dug him out of the pile up and started laughing! I had worked him in his mobile several ti
