I)enr Sirs:

Letters near TAt

First I would like to tell you that It has been several years since I have picked up a copy of 7 3, This happened because I more or less was interested in the hobby for a while. At that time 1 was subscribing to QST, CQ, 73, and VHF AMATEUR. I let all of them run out except QST.

About two months ago E picked up a copy of 73 a friend had down at work. After spend« ing several days almost reading it cover to cover I ordered the following books: Military TV, Index to Surplus, ATV-Anthology, and Parametric Amplifiers. I must say I was very impressed with the quality and material of the books.

For the past couple of weeks now my interest has been steadily building to the point where I have now checked out a 6 meter converter, purchased a used 2 meter converter and pre amp., dusted off the old BC-312, mounted the 6&2 meter beams, and will soon be trying the Heath Kit Seneca to see if it blows up when I turn it on. 1 also use to work on 432 MHz but that will have to wait for a little while,

I can honestly say that all of this interest has been sparked by reading a couple recent issues of 73. The many technical articles are related to up to date circuits and modern components, There are at least a hair' dozen cir* cuits I have seen in the October and December Issues that 1 would like to build.

Now the reason I am writing this letter Is that I have a rather unusual request. I would Hike to start another subscription to 73 with the October liMl« Issue* This is the first issue that I looked at and there are a couple of the circuits in it that I would like to build. T am afraid that I could not get a single copy away from my friend for anything- Trying to find 73s In the second hand book stores around here is a lost cause also.

So if it Is not too much trouble wotild you please start by subscription with the October 1966 issue. If this can not be done then do the next best thing and start with the latest issue.

Hear T*Ir, Greeni

An agreement permitting U.S. amateur radio operators to operate in India was recently concluded with the Government of India. Under the procedures established, an American amateur who wishes to operate in India should apply to do so, preferably before leaving the US,, by writing to the Wireless Adviser to the Government of India* Department of Communications, Sardar Patel Bhavanr Sardar Square, Parliament Street, New Delhi l„ India. The writer should receive full details by return mail. You might be interested to know that several Americans are already availing themselves of this opportunity and have received licenses to operate amateur radio stations In India.

I would like to correspond with a amateur who would like to assist a veterinarian in assembling equipment to monitor the heartbeat of an animal. I want to put a mike jack into the side of a pocket-size two-way radio thai can be attached to the harness on the animal, so I can monitor it from my car, which has a receiver in it, I also need a sensitive amplifier to pick up the same on animals inside by clinic. Since I know nothing about building such, 1 need the expert advice of a ham interested in the field of veterinary medicine. Would appreciate hearing from anyone.

Dear 73i

Reference is made to Bob Renfro's, WA4NXC, very interesting article in the November issue on the Air Force Eastern Test Range.

Since mention was made to the range prime and sub contractors, FA A and RCA, respectively, let us not forget another range contractor who is instrumental in up-grading the capabilities of the Eastern Test Range,

Federal Electric Corporation (ITT) is presently installing a submarine cable system for the Air Force, between Cape Kennedy and the downrange islands. The new Cable will provide up to 270 4kHz channels on which telementry and tracking data, and voice messages, will be sent to the Cape in "real time/'
