Dick, I don't see why it would not work. It is a Lacquer based primer and should not contain any lead products. However, I would query the SteppIR folks to be safe. The primer I use is: "Dupli-Color"
Mike, My Daughter had a swimming pool installed in a very rocky area. They dug the hole using a Bobcat mounted Jack Hammer. You might check the heavy equipment rental guys and see if you can locate o
Hans, Most gamma matches have a capacitor consisting of the feed coax or an insulated rod inside the outer rod. This is the series capacitor. Its adjusted by moving the outer rod in and out. This giv
Rob, You can use the MFJ-259 as a Dipper. All you need is a 2-3 turn loop soldered to a connector. I have the MFJ-269 and have used it many times to determine resonance of L/C circuits. I have a few
Dan, I have just installed an additional 8 ft. ground rod. I used a 5/8 copper clad steel ground rod from Home Depot. It went in very easy in caliche/limestone base below the top soil. I used a small
Terry, I have used a Prop Pitch rotor for the past 40 plus years and have always had slow response during cold weather. It rarely freezes for any duration here in central Texas, But the rotor thinks
Another option is clothes line. You can get it at most hardware stores. Its available in vinyl covered steel. It is small diameter and very strong. It has supported a 5 band vertical for several year
I use Aircraft stainless steel control cable for my inverted V's / slopers. They are tight and sag is minimal since I also use them as guy wires. I install them fixed at the top of the tower and allo
Mike, Check with a swimming pool installer. They install pools in rock or anywhere else. if they dont do the work themselves. I'm sure they could recommend the contractor they use to did the holes. A
Ted, There are several good Logging programs that will provide what you are looking for through software. I use Logger32. It has a sizeable Tracking map (Great Circle) that displays the rotor positio
Check the brushes. A worn brush will sometimes jam in one direction and still run ok in the other direction. 73s de Jim W5IFP _______________________________________________ _________________________
Kathy, I can attest that Dr. Pepper cans worked just as good as Beer cans and the antenna did not get drunk. But 40 meters sure took a lot of cans and solder. 73s de Jim W5IFP _______________________
Martin, I would suggest you install a Hazer. Then you could lower the antenna to work on it near ground level. 73s de Jim W5IFP _______________________________________________ _______________________
You can install the guy wires at the top of the tower above the Hazer. Use a longer mast. Then you loosen two guy wires to lower the antenna. Once the antenna is lowered, you can re-install the two g

Jim, Might I suggest you consider installing a Hazer: http://www.glenmartin.com/catalog/page10.html That way you can keep the TH-7 and lower it for any maintenance. 73s de Jim W5IFP _________________

Hans, Why not make the ground rod functional. I use a 3 band (144/223/440) J-Pole on top of my tower. I have a TH-6DXX with a 2M 14el beam above that and then the J-Pole on top. I built it using 1/2,
Dan, Sounds like a perhaps a waveform issue. This is especially critical on rotors that use a series capacitor on the motor. The Inverter may not be putting out a good sinewave. Perhaps it is more li
Charlie, You can go basic or elaborate, depending on the need: time/budget I modified an RCS-4 for my Son-n-law. To simplify the switching we installed a 4 wire control line and eliminated the RF cir
