All, Would there be any noticeable pattern changes while receiving on a Yagi antenna i.e., reduced f/b f/s if it's balun became faulty? If so, could this happen with a 1:1 bead type balun? Tony _____
Hi Jim, Thanks for the informative reply. I have an M2 mono band Yagi and I'm using the 1:1 balun that M2 supplied with the antenna. I'm told there are better baluns available and was wondering if yo
Thanks for all Steve... Jim Browns excellent paper on baluns is a real eyeopener. Seems there isn't anything commercially available that can duplicate the line isolation of his home brew ideas. The F
All, Jim Browns paper on baluns and chokes is very informative. It's written so even a layman (like me) can get the gist of what a choke is supposed to do. As far as I can tell, the pattern on my M-S
Thanks for all Steve... The total length of feed line to the rig is about 85 feet. It's grounded at 70 feet where it then goes into the shack using a 15 foot jumper. Which do you take into account as
All, Has anyone had any problems fitting LMR400 PL-259 crimp-on connectors to Davis Buryflex cable? Their dimensions seem close, but I thought I'd ask before I use them. Thanks Tony, K2MO ___________
All, There seems to be pros and cons when it comes to using dielectric grease (STUF) on connectors. Flooding or sealing the connector at both ends seems controversial since it might actually cause ai
All, I've always assumed that UHF connectors had negligible insertion loss below 30MHz, but I recently spotted a couple of quotes on the web that put losses between 0.3 and 0.5db @ 30Mhz. If that wer
All, Came across this Youtube video on Wrenchlok ground connectors. They appear to make a solid connection. http://www.youtube.com/watch?v=s-TRfm9n8ng Tony ___________________________________________
All, My Yaesu 1000 rotator stopped working today. It's locked in position and does not move. I tried connecting another 1000DXA control box to it and it's still dead. The connector at the rotor is cl
Mike: I pushed the pins into the connector a little further. They seem to be making contact, but the problem still exists. I'd like to see if the rotor will spin by applying DC power to it, but can't
Thanks for the info Peter... It turns out that pins 1 through 3 are for the 500 ohm position pot. Pins 4 and 5 are connected to the DC motor. Viewing the connector on the back of the controller, the
I'm hoping it's a broken cable Henk, but if it is the rotor, I'll probably buy a Yaesu 2800 this time. It should handle my 20 meter 5el mono band Yagi + 3 el Steppir better than the 1000. I just hope
All, I called Fulton and asked if the bolt pattern on their K2550 winch was the same as the K1550. The tech said it was close, but not a match. I know that more than one member of this reflector has
All, I'll be installing a new Yaesu G-2800 rotor next week to replace a broken G-1000. The rotor had been making noise before it finally stopped turning so it's most likely mechanical failure. The ma
Dick et al... Thanks for the suggestions and comments. I installed the new Yaesu G-2800 this week and decided to use the shear pin. This rotor seems to be a big step up from the G-1000 and I think it
All, Has anyone heard of any positive or negative reports about the MFJ-994BRT remote Tuner? It's sells for $379 at HRO and is supposed to handle 600 watts. http://www.hamradio.com/detail.cfm?pid=H0-
All: I recently spoke to a ham who was using an active loop antenna for low-band reception on 80 and 160 meters. He said the signal-to-noise ratio was far better on the magnetic loop than it is on lo
All: My shacks location makes it difficult to keep ladder line away from other cables that enter the house. Someone suggested I use 2 runs of RG-11 coax in parallel to route the coax inside the house
All: My crank-up tower is located a few feet from the house and each leg is attached to a ground rod that's about a foot or so away from the foundation. I'd like to add 3 more rods in a radial patter
