Is the SAL-30 available piecemeal? I have plenty of wire, coax, enclosures, support tubing, etc, and would just need the proprietary controller Since I already have 5 two wire 500-750' Beverages for
Utility company telemetry and control over the wires maybe? Carl KM1H I live in Waco Texas and there are no known windmils or inverters nearby that I know of. I have a lowband noise that is pretty br
I used it on 1296 a bit over 30 years ago, however both ends have to agree on which rotation they will use. I suspect it is more standardized now. And a lot easier to make power than a ring of 7289's
Hey, you had plenty of advanced warning this one was going to be brutal! I hope you and anyone else in the path get thru it OK. The 2008 ice storm up here still shows plenty of scars and some of my V
You can always prepare for your own safety Eddy; cut down trees that imperil buildings and vehicles, have a generator already pretested and in place, chain saw ready and tested in case you need to cu
From what I see on the forcasts I'll also be needing luck. Once the snow hits about 5AM the winds will be slowly rising with the temperature and once it hits about 31 it will be in double digits reac
Thats good news Charlie. After about 4 hrs of fluff it started coming down pretty heavy maybe 20 minutes ago, no winds yet. This photo could be my road about half way down the hill, houses on the low
While Tom touched on the subject yesterday the subject of an individuals ground conductivity has to be stressed, continuously it seems. The FCC maps arent perfect and hams usually dont have the optio
I used a noise bridge to cut all the RG-11 stacked yagi and phased verticals phasing lines as well as harmonic stubs here when running a 2 station single op contest, before SO2R. Using the station re
Null depth is a function of cable loss. ** Yup Heliax produces the deepest null, small diameter coax (RG-59, RG-58) is quite poor ** The highest VF and lowest loss produces the deepest null but also
Not always -- stubs made with higher Vf cables are longer, so in my experience they come out about the same for attenuation and bandwidth. The only way to get a deeper null (with the reduction in ban
The lowest loss cable I have here is 75 Ohm 1" General Cable Fused Disc; its under a differnt name these days. Mostly air with poly discs and used for the 200' runs for 10M, 2M, and 222 MHz. For the
The proper ferrites work well down into any frequency you want, even LF. I use them into UHF as a way to keep 2 and 4 bay yagis from having distorted patterns that can kill a good F/B. Several A-B te

Dielectric losses become evident at 2M with 1500W and at 432 400W of steady carrier will heat up even the best N connectors and RG-213. For that reason many are switching to the 7/16 DIN. That has no
Im not concerned by what is measured at the matching unit or a miniscule cable loss; just what is transformed back to the amp and its ability to load at full power without arcing, running out of or h
That 1.3 is only at ONE frequency Charlie, he is not crystal controlled. What is the 2:1 bandwidth at the amp? Carl KM1H -- Original Message -- From: "Charlie Cunningham" <charlie-cunningham@nc.rr.co
Charlie youre continually missing the point; ignore cable loss period. The only issue is what impedance does the amp see from lets say 1800 to 1900 KHz? AND can the amp load into it without a problem
I suppose I missed that part while doing things around here but this is the only pertinent info I can find from him. Nowhere does it say he has a 1:1 anywhere with the cap in the cabinet. Granted som
That is the type of report I really like to hear Carl. All that work has paid off in spades. As you increase the number of radials the VSWR bandwidth might decrease along with the R which is normal a
