Lets look in Bill Orr's VHF Handbook. Plenty ot real good dope in there on lots of VHF problems. A good 3M pages entitled Analysis of neutralizing circuits, Starts right in with a tetrode tube. No mention of triodes there. Further along in the book under he grounded-grid rf amplifier we find One of the undesirable characteristics of the conventional triode rf amplifier is that the stage must be neutralized to prevent self-oscillation. As the frequency of operation is raised the stage becomes...

T just finished reading through the September issue of 73 and was quite interested in the article Mors On the 6DOS by K5JKX. 1 believe I have another interesting little bit of information that can be added to this that will only help to verify his information.

Spiralray Antena

the midget model with 27 ft. boom, that is. The big brothers have booms some 36 and 47 feet long respectively. The Spiralray is a mighty odd looking beast. It looks like a big Vagi that has been through a tornado. The elements make a 90 degree twist between the relict'tor and the last director. The theory is that the Spiralray transmits a circularly polarized signal, similar to a heliv. Like a helix it attains maximum gain when the antenna at the other end is also a Spiralray. In the case of...

Dc connection to the 5894 plate is made through an rf choke visible in the bottom-view photo directly behind the meter switch. The ead from this choke runs through a -inch clearance hole in the chassis, through a 1 16-inch hole in the phenolic sheet, to the brass plate, where it is soldered. The other lead goes to the meter switch shunt assembly, Rf output from the 5894 tank comes from a link made of No. 12 wire which is insulated with Teflon tuning. The link is 2K inches above the chassis, and...
