Hi, I was sent here by some folks from RAT (rec.audio.tubes), and was attracted by the "boatanchor" part of this NG's name - descriptive of, pretty much, everything I'm into. From old RCA racks filled with ancient test gear & power supplies to restoring vintage recording gear etc., etc. Restoring vintage cameras got me interested in photography, and now... My Mr. Know-It-All bliss came to an end when a friend gave me a (Henry?) Tempo One transceiver & an ECI (no model name) Linear Amp (both flea finds). I *Had* to bring them up - downloaded the operating manual & schematics for Tempo One, cleaned the rotary switches etc, brought up the power, and managed to align the receiver the best I could (all my test gear is mainly audio, funct. generators only going up to 1 & 2 KHz, so had to rely on harmonics to get the RF outs' them (triangle)... Got the transmitter section putting out *some sort* of rf into a dummy load (once again, followed the manual's step-by step idiot guide). The dummy load was a *wirewound* 50Ohm resistor in a can of motor oil (i know it must be an absurd load for RF, but i had nothing non-inductive - any hints?) Anyhow, here are my problems & questions: I'm pretty much RF illiterate, and don't have an operator's license. I remember thinking of getting one as a kid, but code didn't come too easy. Some HAM at a swap meet told me that code is no longer required - is there a site where I could download a sample exam / list of requirements? An appy which I could download so I could hook up to a soundcard of my computer to encode /decode Morse code (I could build any required peripherals)? A FAQ for this NG? Any info on NYC swaps (I just moved from Boston a while ago, the MIT swap was amazing...) Any hints /tricks? Any info (schematics /manual?) on the ECI linear amp (no model on the case (chrome with 2 meters & machined aluminum knobs wgich look just like the early AKAI knobs), a bunch of gas voltage regulators, and a single octal / top plate output toob, can't remember the name, looks like an oversized 2e26. Any info / feedback would be nice, Thanks in advance, -dim Don't know what the ECI is. The 50 Ohm resistor is fine. I used to use a lightbulb on my DX-60. Now I just load up a wire. If you got the Tempo working and were able to load up the transmitter, you'll have no problem with the theory part of the exams. The exams cover 3 broad areas, theory -which you have knocked except maybe you need to pick up some HF, power, and mode jargon, SSB, XTAL filter, passband tuning, PSK-3, envelope, key click, 2,000 VDC, oil capacitor, director element, balun, SWR, if this makes sense, no sweat. practice - If the net control asks for xxxx, what do you do...., and regulations - on 14,065 kHz can you call CQ on LSB? www.qrz.com has practice exams and you can download the entire pool from www.arrl.com. I've been hoping that the FCC changes the regs to give more privileges to techs (including HF SSB) and makes the General and Extra exams more difficult. de ah6gi/4 check out my boatanchor page at www.kiyoinc.com/heathstuff.html and flame away on codenocode at groups.yahoo.com/group/codenocode -- |
