My interests right now are both ragchewing and DXing using both CW and SSB. I've read the reviews, etc., and would like any input you have about the performance of these rigs. If you have had a chance to use both of these rigs, a comparison would be great!

Well, at very least, _you_ seem to be out to get him, or at least, you message carried some rather nasty overtones that I doubt reflect the way you'd really like us all to think of you -- or the way I imagine you'd like people to think of hams. People have all sorts of reasons for wanting anonymity. You don't even know if this message was from here in the U.S., and certainly I'd guess you'll concede that even if our government plays by the rules most of time, there are occasionally some spectacular lapses, and if you look outside the US, often, anything goes. Seems to me that if you're unable or unwilling to offer the assistance requested, that simply ignoring the request would be sufficient. Or if you'd be willing to help, but only under certain conditions (e.g., that the group requesting assistance disclose in private email the necessary facts to satisfy you) then say so and be done with it. I don't see a real need to be nasty and I'm sure, on reflection, you'll agree. I just don't believe this post reflects your true attitudes. You're a nicer guy than that, I think.

Well, depending on your country, you can pour a gallon of gasoline all over the upholstery and then set the car on fire. That should take care of the transmitter. Should solve the problem with the undercover types following the car as well.

After going through a couple of SWR/PWR meters that I thought were defective, I am beginning to think there might actually be a problem with my radio. Using a couple of different meters, I consistently measure very low power-- maybe 200 mW when it should be putting out 50 W. I find it difficult to believe that is all the power the unit is putting out (on 2 m) but that's what the meter says. No one complains about my audio quality and my PC screen even cants a little when I key the mike on high power. However, the reading remains. The only thing I could have possibly done to the radio is key the mike without the antenna attached-- this is bad, I'm sure, but would it necessarily be fatal? Could I still be putting out a signal with reduced power or would the failure be catastrophic? Now I ask, is there any way that I could screw up using the SWR meter? I mean it's not Big Science. Suggestions? Thanks, Eric E. Snyder Department of MCD Biology ...making feet for childrens' shoes.

Well, indeed there is a failure mode where you would be putting out a couple hundred mills. First thing to test is if your power supply is delivering 10 amps or more on full power xmit. Then, get someones known working power meter and cables. You could also do a de-facto test and A-B the mobile against an HT connected into the same antenna..running at low power. Compare your quieting into the repeater with different power settings on the HT and match it to the quieting on the mobil. If you do find out that you are generating 200MW, there is a great chance that your modular power amp in the Yaesu is fried. Have at it.

I have read reviews stating that it is capable of wide band reception, however mine is limited to amateur band FM only. Interestingly, there appears to be AM reception capacity within the circuit diagram. 73's Bruce, VK6XZ cascade@iinet.com.au huntbw@cs.curtin.edu.au ------------------------------ Date: 15 Mar 1994 21:21:30 GMT From: ihnp4.ucsd.edu!swrinde!cs.utexas.edu!howland.reston.ans.net!news.ans.net!newsgate.watson.ibm.com!watnews.watson.ibm.com!watson.ibm.com!uri@network.ucsd.edu To: ham-equip@ucsd.edu References <2m4qak$at9@news.iastate.edu>, <2m4s8t$3vq@doc.cc.utexas.edu>, <2m4sff$423@doc.cc.utexas.edu>ews Reply-To : uri@watson.ibm.com Subject : Re: FT-990 vs TS-850 In article <2m4sff$423@doc.cc.utexas.edu>, kreblon@doc.cc.utexas.edu (Bob Nagy) writes: > Ken..I own the 850..The reliability is better on the 990...
