On the above comment , I mention couplers that are in radio diagrams ....not the Bird. They switch the diode to measure forward and reverse readings. If there is any capacitive coupling into the link
Hi Heath. When you check the resistances , be sure to check from the primary to the core and the same for the secondary as the insulation to the core that would normally be at ground potential is som
Hi Gary. The output side of the tuner looking into the resistive load is reactive and is determined by the line length , velocity factor and frequency. If you have a reference on Smith Charts, you w
Hi Gary. If that is the case , it still is valid to use the Smith Chart with a zero line length . It has been a while since I played with one so I didn't dig it out an go through it. I believe you st
Hi Mike. Mike Gary mentions that his resistance is directly connected to the meter and is non-reactive . There wouldn't be any reflected power in this situation and the load and tuner output would be
I agree completely. I always object to those hams that think that everything they do is fine and any one less than them is a problem. I came from the CB band 20 years ago so I guess I am a CBer too.
I have thouroughly solved both problems of lightning and rf by using my cold water pipe. As we all know , the cold water pipe is the BEST ground that one can obtain and so I have expanded my cold wat
Actually , I had my petition to the zoning board of Cleveland denied to allow me to construct a 50 ft tower instead of a 35 ft that is currently allowed. One of the Black board members had a foul mou
When the amps are outlawed , Hams will start building them in their garages and sell them making great profits. There are hundreds of hams doing this and also many making the 10KW + amps for themselv
Like it or not Steve, the lion share of Hams are coming from the CB band as I told you before. Their numbers carry significant weight and the ARRL as well as other groups will depend on their numbers
Prototype PCB run ~$300 for 1 or two PCBs to about ~$500 for about 25 to 50 boards where the lower numbers would be for a physically larger board. This includes about $200+ for the artwork. I use him
Hi Dave. My comment is that air breaks down at 20 KV/cm meaning that there would be an arc over at that field strength. I didn't look it up but it happens to be one of those goofy things that sticks
Hi Al. I cut the HV windings from a small one and rewound it with HV wire to use as a filament transformer. Applying 120 volts to the primary gets the core hot so evidently , the load from the second
Hello All. The safty issue stems from the fact that it requires about 32 volts DC to maintain a plasma arc in air. If 18 lead acid cells are used , the charging voltage is 2.33 X 18 = 42 and the disc
