The specific question is will one of the smaller rotors work with the $100/200W units? Primary interest is use a backup power supply (marine battery) for emergency services. I know that some of the cheaper inverters only put out square waves. Does this cause a problem?

SSB no good! To: info-hams@ucsd.edu This weekend my Brother-in-law "dug-out" (literally) a SW radio Hallicrafters S-76. It is a 9 tube unit double conversion Superhetrodyne receiver. I threw on a single long wire (will improve this later) and turned it on lo and behold it warmed and started to work. My B-in-L estimated that the unit wasn't powered up for AT LEAST 15 years . I jumped to the 80 meter band and recieved CW fine. however when I went up in the band to do SSB I go lots of signals but they were all distorted/muffled The unit has a switch for either CW or AM reception. The manual says that if I use the narrowest (sharp) filter and tune in the station then switch to the widest filter it will then be ok for SSB reception. The afore mention switch engages a BFO when switched to CW mode, but I didn't read anything about AM. Has anyone used one of these old birds?? Has modern technology of todays transmitters made this units SSB or Psuedo-SSB capabilities a thing for the muesum shelf (although it work fine for CW!!)? Maybe something is lacking due to age or lack of use??

You are probably overdriving the detector. With the BFO on, the AGC doesn't work, so the incoming signal can easily overdrive the detector. (It's not a problem on CW since distortion doesn't affect copyability.) Try turning down the RF gain control.

The SSB reception is very touchy. CW mode is right, but you then need to use the band spread knob to very carefully adjust the frequency. The pitch control also helps on this. ------------------------------ Date: Mon, 14 Mar 1994 23:21:05 GMT From: ihnp4.ucsd.edu!munnari.oz.au!newshost.anu.edu.au!sserve!usage!metro!ipso!rwc@network.ucsd.edu Subject: IPS Daily Report 14 March 94 To: info-hams@ucsd.edu SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT ISSUED AT 14/2330Z MARCH 1994 BY IPS RADIO AND SPACE SERVICES FROM THE REGIONAL WARNING CENTRE (RWC), SYDNEY.

To: info-hams@ucsd.edu > I am having a hard time deciding between the Kenwood TM-732 > and the Yaesu FT-5100. Can anyone give me their opinion. Jon, If you live in a metropolitan area then I recommend that you NOT buy a TM-732. I live in Dallas and had to get rid of mine in less than a year. It is a feature-laden radio, but it has poor rejection. As a result you hear lots of "intermod", even with CTCSS decode turned on. If you look at the service manual, there is only one adjustment pot in the receiver, which only helped the problem by deafening the receiver to the point of unusability. In the home or in rural areas it would work fine. In heavy RF environments it becomes very annoying. I have at least 6 friends with the same radio and the same problem, but since they don't go downtown very often they have just put up with the occasional racket. I couldn't. I bought a TM-742 that has individual band modules and it works great. (See, I'm not anti-Kenwood!) I don't know anything about the Yaesu FT-5100. Hope this helps. John -- John A.
