I have been told by Mike at M2 that I should have an additional bearing, or bushing, above my Orion rotor. I have the flat beacon plate with a thrust bearing at the top of the tower. According to Mik
Page 154, October 2002 QST: "performs as predicted by YO and EZNEC within .25-.50 dB" is patently unverifiable. I have no problem with the ad included a chart based on computer modeling but they have
How did they confirm the power losses in the conductors were 0.17 dB? Did they put the entire antenna in an infinitely large thermos bottle and measure the heat gain? Or did they use a COMPUTER MODEL
I have used the multi-pack of SCOTCH brand colored tape available at Target stores. In outdoor usage, the Red has faded severely after a couple of years in sunlight. The Yellow, Green, and White have
I bought a bottle of 242 Loctite at my local Fastenal store for about $40. I used it yesterday on the hardware for the driven element; carefully snapping back the tip to seal the bottle. Today, the b
I just received some coax from Tessco that is supposed to be Belden 8267 RG-213. There is no marking of any sort on the jacket, which is a dull black, not the shiny-er black that I normally associate
Thanks for the info from the members of this group. The Belden people indicated to me that there should be markings every two feet, which I couldn't find in the light of my garage workshop or the dif
Ron Chambers (and friends) The easiest way to increase the voltage to your DC powered rotator is to merely install an outboard DC power supply in series with the negative lead from your Orion control
Beware that much of the LMR-400 type cable available at attractive prices has aluminum braid, which requires special crimp-on connectors. The original LMR-400 and CNT-400 has copper braid over the al
Tessco currently shows the Rohn 45JBK (set of 6 bolts & nuts) for $4.70 list ($4.14 "gold" level pricing) also, the 25JBK $2.80 ($2.45) and the 55JBK $5.05 ($4.43). When I purchased the 45JBK some ye
I use 7 x #18 cable - 3 for the pot and double the others (equivalent to #15) for 400 foot plus runs to my 1022 rings. Works fine with moderate sized antennas (11 element 38 foot boom 10/15meter duob
It is very easy to drill accurate holes for the 3/8" bolt to pin the mast - just tightly bolt the clamp into place, and then use the holes in the clamp as a drill guide from each side. The M2 clamp i
I seem to be having some problems with my small prop pitch rotor freezing up When the temperature is below freezing. I'm assuming it's a two part problem. First, water must be getting in somehow. Sec
I still have an M2 Orion box for my prop-pitch rotor; used a different Orion box for my Orion rotor. Generally, I am happy with the 12 programmable presets; covers 99% of my contesting needs. The Ori
degs. The digital display always shows the CURRENT heading. You simply crank the knob over from say ZL land to say EU [ 30 deg from me].... and sit back and watch the show. After a brief pause, the r
What do you mean by 'smoking?' Does a fuse blow? Does the control box stop smoking when you fire it up on the dining room table? You should be able to turn the DC Orion with a 12v power supply or bat
The OR2800DC runs on 30-47VDC. Polarity determines rotation direction and voltage determines speed. If the control box is smoking, there is probably a stray wire strand shorted in the control cable s
All the big cables connecting my lightning rods are installed inside the attics, right next to the ridgepoles. Terry Zivney, N4TZ/9 _______________________________________________ ___________________
I have had a similar problem - if any of the motor windings have a low resistance to ground, turn on. Looking at the schematic, the output of the power supply is turned on by a low impedance to groun
I have the M2 box for my Kurt's prop pitch - the BOX has been pretty reliable..... and is much cheaper to ship back and forth than the prop pitch assembly :^( I also have the old M2 box for my Orion
