Dig the item on e-bay.. He can't spell either.. Title: EIMAC 4-1000A X 2 "8KW' RF DECK BIRD METER http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1361053282 THIS RF DECK IS IN GOOD SHAP USING TWO
Early days there was very little use for linear amplifiers. Most were using AM (plate modulation) or CW. So the question may be what was the first Radio Amateur RF Power Amplifier ( with or without m
If you want maintain the same Q in PI section you will have to increase the value of the output capacitor and increase it's spacing because the impedance at that point is higher than 50 ohms and the
I have several things that I am willing to take to Dayton only if a Licensed Amateur (general, adv or extra) is willing to buy(maybe swap) them and pick them up there. If anyone is interested we can
I am packing up tomorrow so if anyone wants load up anything please let me know. 73 Bill wa4lav spaces 2904,2905 -- StripMime Report -- processed MIME parts -- multipart/alternative text/plain (text
Last call for heavy stuff for dayton. I will be loading the van in a couple of hours. 73 Bill wa4lav You may want to email me at home at wa4lav@arrl.net just in case I have left work. 73 Bill wa4lav
A fundamental and its harmonics produce a waveform with same period and frequency as the fundamental frequency. If you introduce a "subharmonic" (a fractional frequency) then the "subharmonic" become
The paper published only describes superharmonics. None of the equations illustrate "Subharmonics". Also, It is possible in situations involving differential equations with a "time/amplitude dependen
I have not looked at the manual but I expect that there is a loop, a resistor, and a diode detector inside the slug. The loop does produce a voltage proportional to current in the feed-line center co
Someone help me out here. I am tired after a long day and may have some typos. There is both capacitive and inductive coupling to the loop in the slug in the Bird watt meter. The voltage to current r
I made that statement because the device detects the vector sum of the voltages generated by both capacitive and inductive coupling. Even though you may use a perfect square-law detector ( a diode co
By the way, I am in the need of a replacement meter (30uA)for a Bird® 43. I have some slugs and couplers and would like to make use of them. 73 Bill wa4lav
The self inductance of a straight wire can be found at http://www.hills2.u-net.com/electron/induct.htm#StraightWire However, how do you measure it without or use it with out making a loop? Unless you
Please define a little less vacuum. I don't have any experience with Covimag's 4-400 tubes but I do with its bigger brother. If Covimag 4RP1000A's had a little less vacuum I'd expect they would not p
I think part of the misconception that carbon anode tubes are more gassy is because when most people look at one they associate the carbon with something more familiar to them. Namely charcoal. Charc
