Jim Weir: RST-442E operation query
Jim, I'm still troubleshooting a squelch problem - I can't easily overcome the squelch - on my RST-442E and have a query re the Operations and Maintenance Manual content. Section C. 3. Troubleshooting Procedures. Audio Microphone Response Tests (a) and (b) on Page C5 note that the output of U101A pin 1 should be 3.5 volts peak to peak from a 0.5 volts P-P microphone input [speech] but Section D. Theory of Operation para 1 on Page D1 notes the output at U101A pin 1 from speech will 1 volt peak to peak. Which is correct? Thanks, Leo |

I really would like to help, but...
Please, please, slow up and try it again. Please use whole sentences and don't abbreviate. Tell me what YOU are measuring. I can read the manual on this end.

[SNIP] With all due respect for Jim, who has lots of valuable experience and great products to offer, why is r.a.h. being used as a tech support centre for RST Engineering? Some of the questions may be of interest to other builders, but many of these "Jim Weir: help my hat's on fire" messages should not be here. Would it be very much trouble to head over to http://www.rst-engr.com/rst/contact_us.html and get in touch with Jim that way? Or maybe start a rec.aviation.jim.weir.questions newsgroup?? Just curious... Rob |

If *you* do not, set up some filters to get rid of the RST, or Weir, or whatever subjects, of just mark the topics read when you come across them. My vote is to leave the questions here. -- Jim in NC |

Rob,
I queried Jim direct but he didn't respond so I posted to him here as others do and got a fast reply. I think Jim prefers it that way because an answer to one individual often satisfies others with the same query who haven't asked. He kicked my query back with a 'simplify' so you'll have to bear another post when I re-phrase it. Happy flying, Leo "Rob Turk" wrote in message news:%X%ae.2221$184.2009@amstwist00...

So many of the posts are a morass of worthless personal invective: complain about those, why don't you? |

Actually,
I read in the old kitplanes article about Jim's Magneto Timer that he prefers to be asked questions in this forum and not by personal email. I think it is very fitting as this is a homebuilt newsgroup. Isn't that the entire point of this newsgroup to find out info on building our airplanes, and getting useful advice from each other? I would guess Jim's email is clogged up with biz stuff! I am more than happy to post a question here for him and wait for him to have time to reply at his leisure. Heck it may even be called being polite? Patrick student SPL aircraft structural mech |

Agreed, even though my (huh?) number is hovering right around 95%. I don't think the OP is on the mark, critiquing people for posting questions for RST Engineering on theses newsgroups - the help solicited from Jim/RST has been primarily for airplane applications, IIRC. Somewhat troubling however ...Jim W has branched out into real estate these days. g Montblack |
