Products SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).[email protected]

The ONER HF Transmitter by GM3OXX The Oner HF CW transmitter was first described by George, GM3OXX in Sprat number 45 and has been widely used as a simple but effective transmitter. It is so called because it can be built on a PCB just one inch square! http://www.zerobeat.net/g3ycc/oner.htm
ICOM IC-7300 HF Plus 50 MHz Transceivers employ a new-technology real-time touch-screen spectrum scope that leads its class in resolution, sweep speed and dynamic range. While listening to received audio, you can check the real-time spectrum scope and quickly move to another signal. When you first touch the scope screen around the intended signal, the touched part is magnified.
The transmitter power transformer is a Stancor P4004 (175 ma DC rating) rather than the larger 200 ma rated Triad R-121-A. The P4004 was an old design in 1962 since it appears as XP-4004 in a 1937 Stancor catalog (for $8.50)1. Filter capacitors are the unusual 16 µF, 700Get Price
