This will give any newcomer a bad feeling of being snubbed. As you've listened to their conversations, I cannot, for the life in me, understand why you would want to converse with them. "W11WWW Monitoring" is a clique - call. some member of his clique will respond to him. You, as a non-clique member will get no response to such a call because there is no-one in your clique (Those who do it are actually in transmit when they say they're monitoring :-) No clique member will EVER call CQ on 2m or on any repeater because it risks ANYONE replying. There are terrible penalties for any clique member calling CQ or talking to strangers that make the Wouff Hongg seem tame. There are a few people worth meeting on the air, but it takes some effort to find them in some areas. It is worth the effort, though. : : I also wonder what all of these knobs on my HF rig (Kenwood TS-820) do. : The manual does not tell me, it just gives a tune up procedure. How : do I adjust my power on CW or SSB so as not to be rude like other : hams I hear on HF? Does the fact that I can't guess the answer because : of poor manuals make me a bad person or am I just stupid? NOW here I can help.... Your output valves have about an 800v power supply. The anodes are fed via an inductor (RF choke) so 800v is their average DC level. Any signal voltage will be an AC voltage superimposed on this. The anodes cannot go very close to ground potential (you don't want to go too far below the screen grid voltage of 250v or so, or else the screen starts to draw increased current and can overheat) This means the anodes can do about a 500v swing down to 300v above ground. During the other half of the cycle, they will swing 500v above their power supply to 1300v above ground. Got the picture ? OK. We have a 1000 volt peak-peak AC signal. How much power this relates to is undefined. It depends what resistive load impedance it is applied to. 1000v p-p is about 350v RMS. To take 100watts from this we use 100=V^2/R and get a load resistor of about 1200 ohms. At RF this is a very high impedance. To design a transformer to transform a 50 ohm load or antenna to 1200 ohms, AND withstand a kilovolt is a tall order. Some filtering is also needed. Way back in the mists of time, someone decided to do the transformation with a tapped resonant circuit and do both jobs with one circuit. A simple loop of 2 caps and one inductor. The high voltage input is applied across the smaller capacitor, the low impedance low voltage load is applied across the larger capacitor. OK so far? The junction of the two capacitors is chosen as the ground point as it makes life easier. A blocking capacitor is used in the feed from the anodes to block the DC component (800v) This is the classic Pi Tank. If you want less power, set the output capacitance larger (labelled LIGHTER loading on your panel just to create confusion!) and set the input capacitance a little lower until you get resonance again. You have changed the tappings of your resonator so your antenna presents a higher impedance to the anodes and so takes lass current and power. Easy ! Because the input cap (Labelled "PLATE") is much smaller, it has a greater influence on the tuned frequency than the large output cap (Labelled "Loading") to understand this, just think of the formula for 2 caps in series..... Light loading is GOOD, your tubes run less current, last longer run cooler, your pi tank is running with a higher Q, which makes it sharper (and more difficult) to tune, but gives much more attenuation of harmonics. Your Pi tank can be adjusted to avccomodate non-50 ohm loads, rather like a reduced range ATU (It has as much range as many built-in auto ATUs. : : Hey, concept, maybe I'm just new to this and need some help from an : experienced HAM who gives a damn and believes in the ideals that : created this hobby in the first place.

I've found the QRP folk to be very friendly (They even help other competitors in competitions!) There is a list of "Elmers" on usenet. try rec.radio.amateur.info "You are no older than you think you are" is a cliche, but as I estimate my mental age at 6.125, perhaps it's not far off target.

I took my test May 15 and recieved my ticket August 5. After waiting 8 weeks, I was talking to a couple of W5YI guys at a swap meet and they swore that ALL their new licenses were coming back in six-seven weeks. They encouraged me to check on the situation as they thought maybe something had gone wrong. My findings: The local VE's sent the paperwork out on the May 17th, (overnight mail). ARRL, (Association for Retarding Radio Licensing 8-) ), sent it to the FCC on or about June 6. That's about 18 days. In any case, it was somewhere other than at the FCC from May 17 and June 6 or 7. I talked the the folks at ARRL and they were quite nice and helpful. They said that May is a heavy test month and that they are understaffed. W5YI claims they complete the process in 1 day. Of course, W5YI isn't busy dealing with critical stuff like: Wanked all Unincorporated Areas Wanked All Cities Wanked All Counties Wanked All States Wanked All Countries Wanked All Planets Kerchunked All Repeaters etc. ad nauseum. 8-) 8-) I don't mean to disparage contesting or the time honored "Worked All ____" aspect of amateur radio, but if bringing new hams on line is as important as everyone says, shouldn't that have priority? I don't know if W5YI can deliver as fast as they say or not. It might be fun to collect reports from new licensees and make the comparison. For now I suggest that new licensees go through W5YI, if available.

I've inherited my dad's Icom 230 (bought in 1974), and would like to continue using it. The radio appears to receive just fine, and the crystal-controlled tuner has to be TLC'd, but the output section has died. I've already run the radio through a cost estimate with Icom, and they said $200-300. To be honest, I'm hoping to come in a little under that (as I can buy a 229H new for around $325 or so). A friend at work here believe the power amplifier module (PA U-49 on the schematic) is most likely at fault.

Even the sheriff could not argue that. Assuming that the story is completely true, then he did the right thing irregardless of the consequences. The shreriff's department probably knows nothing of amateur radio and they apparently felt that confiscation was necessary - even if they personally agreed with what he did. Whether or not the FCC will support him is the real issue here. When studying for my Tech license, one of the study questions emphasized that in an emergency, anything goes. I am not sure whether this is addressed in part 97 or how much is left for interpretation. I hope that the FCC supports him on this and sees to it that the radio is returned. They may ask him to 'unmodify' his radio. If he is not supported by the FCC, is fined and demands a trial, I don't see how a jury (or even a reasonable judge) could convict him.
