Re: [-] Re: Re: Panasonic/Matsushita Switcher HV-PS u-Wave Oven
Paul Playford
Beyond installing your ECBS and parasitic suppression kits in an SB-220 and a Henry 2K-3 (both worked very well, thank you), the most serious project I have undertaken in the last 40 years is to take a perfectly good Alpha 76A and install a pair of 3CX800A7's in it and modify it for QSK.

Normally, my moto is "If it works, don't fix it." The 76A modification was a serious violation of my moto. However, the thought of a light weight high voltage power supply for my Alpha does have an appeal, especially when I would like to take it on DXpeditions and international airlines are almost to the point of weighing baggage by the ounce. de Paul, W8AEF ----- Original Message -----

开云体育very much so.

Mr. Rauch just censored my reply to the Henry 3KA
Step Start subject which I've posted to Ian White GM3SEK and the
group.
?
It seems that the hand of doom of the AMPS censor
will follow me for ever ;-))))))))))))))))

Since I think my contribution might be of interest
to other AMPS members I will post it on the AMPS bypass list and this

Re: New poll for ham_amplifiers

Peter I would like to see a schematic of that one. Funny?I was just looking at the specs of the 4cx350. I'm not sure if?I want to build an IPA of drive the grid. GG is very stable but needs a lot of drive. I can do class A and get 1500 watts out with 100 watts of drive but more drive is required for QRO.

(Do you suppose I should update? Hi)? I will explore the antenna reflector you mentioned.? It’s finally beginning to get a little cooler in east Texas(55 yesterday AM and 61 this AM) and I am more than ready for things to get quiet on 160.? Bring it on! Thanks again. ? 73, Mike, W5UC

I got so tired of the long term kicking of dead horses that I just started going through my unread mail and automatically clicking AMPs mail as read without opening it or looking at the subject. I should have left long before I did. When I saw the announcement about this reflector, I joined it and unsubscribed to AMPS, then deleted all AMPS messages and the AMPS mailbox from my system. God knows that I enjoy a little fun & BS, but I was having trouble finding boots with high enough tops.Mike -- In the Fall of 1996, when I accepted W8JI's challenge to debate him about parasites on the Internet on rec.amateur- radio.homebrew, I received an e-mail from a Ham in NYC advising me of Rauch's SOP during a debate. Examples: Bluster; bullying; the incredible word avalanche; use of lap-dogs to concur with his every utterance, and to nip at his opponent; and also never admitting to a technical misstep. In a nutshell: hubris. The defense for word avalanches was to read as far as the first technical misstep, stop, delete the rest, concentrate on Rauch's misstep and hang on to it as long as possible before moving on. This procedure seemed to work and in less than two months the debate was pretty much over, or so I thought until I got word from Carl, KM1H, informing me that the Rauchian camp had a brand new playground - the AMPS reflector/mailing-list - and this time it had a moderator/censor to protect Tom. I subscribed to AMPS and within hours I received a telephone call from the moderatpr/censor informing me that I would not be allowed to do to Mr. Rauch what I had just done to him on rec.amateur-radio.homebrew. I found this statement amusing because the worst damage to Mr. Rauch had been done by N7WS' Hewlett-Packard Model 4191A RF Impedance Analyzer. Editorial -- IMO, Mr. Rauch sincerely believes that a debate is not decided until one of the combatants Publically admits error. Thus, my guess is that Tom will never admit that Ni-Cr (resistance- wire) alloys do not have reverse skin-effect at HF, that VHF-resonant circuits can ring, and that the only reason to use resistance-wire in a R/L VHF suppressor is to increase its dissipative ability on 10m/ 12m - thereby reducing its Q & Rp at 100MHz Without toasting R-supp. Alas. cheers, Mike 73,R L MEASURES, AG6K. 805-386-3734 r@... |

Hal,

The softstarter in the Emtron amps is a phase control triac system, not a zero crosser. It allows gradually more of the primary AC sinewave into the powersupply. By doing so there is no need for a series resistor to limit the inrush current. Although the series resistor current limiter is effective I consider the phase control system more gracious. I have put a quicktime movieclip on showing the softstarter power up a lightbulb. Cheers, Dick PA3DUV ----- Original Message -----

Personal------------ REPLY FOLLOWS ------------ I agree 100%, but a distinction needs to be made between "personal grudge matches" and a spirited debate. I too abhor the postings where each side simply calls the other names, questions their parentage and generally reviles them any way they can. That is not the same as questioning the other's knowledge and application of theory, conclusions drawn or recommendations made. Those things SHOULD be questioned when appropriate and it often leads to a heated atmosphere, which I don't mind at all since that usually eventually leads to the truth. At the other end of the spectrum are posts which are so bland as to generate no interest at all. Those also should be avoided like the plague. Like most things in life, there is a balance to be found. 73, Bill W6WRT |

In my view, whenever two highly intelligent and experienced engineers can not agree on what seems to be a simple issue, there is something to be learned by the rest of us. The longer the debate goes on (as long as it stays polite) the more I learn. Earlier this year there was such a debate on the Usenet antenna group about current in a HF mobile loading coil. It was fascinating and I'm glad I followed it. I don't think either side convinced the other, but I learned a lot. Keep it up, guys. :-) Bill, W6WRT |
