I think the mere fact that they came out with the "adapter" means that it will fair poorly for the radio if you simply "plug and play." Remember, the FT-530 runs a lot more power when plugged in (I think it's about 5 watts) and you will notice it heating up to the point of being too hot to hold if you are "long winded." 73, de Greg N6GK ------------------------------ Date: Wed, 2 Feb 1994 17:36:38 GMT From: netcomsv!netcom.com!jfh@decwrl.dec.com Subject: ARRL/QST equipment sale prices?

I am conducting some preliminary market research for a small business which I plan to start during 94. I am considering offering 2m amplifier kits. My questions at this point call for a survey of sorts to determine what features are important and in fact is such a kit likely to have any appeal. Please respond via email if you have opinions on the following. 1. Would you consider building a kit amplifier if the performance was comparable with current market offerings? 2. If yes to question 1, how much savings are required to justify building a kit versus buying a built amplifier. 3. What features would you most like to have in a kit? 4. Are there any features which current market offerings do not have that you would like to see in a kit? 5. Do you think use of amplifiers with HTs, particularly for mobile use would significantly improve your communications? Thanks in advance for any feedback, and please add any additional info that you think is appropriate for this research. -- Robert Craig Newbold Georgia Institute of Technology, Atlanta Georgia, 30332 uucp: ...!{decvax,hplabs,ncar,purdue,rutgers}!gatech!prism!gt6681a Internet: gt6681a@prism.gatech.edu ------------------------------ Date: Sun, 30 Jan 1994 13:35:19 GMT From: metro!news.cs.su.oz.au!harbinger.cc.monash.edu.au!msuinfo!netnews.upenn.edu!newsserver.jvnc.net!darwin.sura.net!jabba.ess.harris.com!mlb.semi.harris.com!controls.ccd.@@munnari.oz.au Subject: Semi QSK on Atlas 350XL To: ham-equip@ucsd.edu I am relatively new to amateur radio. Last August I got my Tech+ and last month I upgraded to Advanced. I've really been interested in HF CW. I bought an Atlas 350XL at a hamfest a couple of months ago and have tuned it to work ok, but while transmitting I often get a Vox feedback that keys the transmitter. No setting of anti-vox, vox gain or delay seems to prevent this. Also, the semi breakin mode does not work at all. The manual mentions that some older 350's do not support semi-QSK and that if you have one to "contact the factory". I can only guess that this means there is a bug in the design. Does anyone out there know of the design error and/or what the mod is to correct it? I have a feeling that my feedback problem is related to this defect. Any help?

To: ham-equip@ucsd.edu I'm posting this for Danny; please direct your replies to him. -Rusty- --- Does anyone out there in net.land know of a way to latch the lamp on the Yaesu FT-470 in the "on" position, as you can on the FT-530? It would sure be handy if you could. On the '530, it's F-LAMP, but this does not appear to work on the '470. Perhaps there's a mod (although I'm skeptical, if it can't already be done from the keyboard). Thanks for any suggestions (except the suggestion to buy a 530...I have one, the '470 is my lovely wife's :-) Danny -- ************************************************************************ * Danny Yarbrough, KE4DXA | Grumman Data Systems |703-713-4136 * * (yarbrda@gdss.grumman.com) | Herndon, VA | * ************************************************************************ -- _____ Rusty Haddock ## KD4WLZ -- Weird Looking Zucchini |\/ o \ o DOMAIN: rusty@btg.com UUCP: uunet!btg!rusty | ( -< O o I planted my antenna farm and aluminum and copper poles |/\__V__/ came up.

What may have happened is that the battery voltage has dropped below one of the thresholds and the internal micro-processor has locked up. Try a full hard reset : Put a pin or similar thru' the RESET hole in the back of the control head. Refit the control head. Press MHz and DVS whilst switching on. Good luck John N.

Actually, the wide Kiwa filter is just a Murata cermaic filter, and so has about the same insertion loss as the original Sony filter. The narrow Kiwa filter is actually a filter module, containing at least one filter and two buffer amps - one on the input, and one on the output.
