Dear Brian, Many thanks for your encouraging approach concerning the AM mode.
I can work all bands on SSB but nothing arrives here in AM, including the neighbourhood: Then it must be the receiver and the antennas... something I have to optmize... although I'm a bit sceptic now about significant results. I'm going to try a Swan 500cx from an OM and see what happens. It should be nice to know better the AM working conditions from G and EA colleagues , to see if I can join them some time.

To: Discussion of AM Radio <[email protected]> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=US-ASCII Dear Jose, I think the problem may be that your TS140 does not have an AM filter. If that is the case, then it is trying to squeeze all of a 6 kHz AM signal through a 2.3 or 2.7 kHz wide SSB filter. It appears to lose al ot of sensitivity, especially on the higher audio frequencies. You will generally find the sensitivity of the receiver sufficient for hearing AM. I do prefer Yaesu rigs on AM over a Kenwood, however, your TS140s certainly ought to be sensitive enough to hear the guys on AM from around Europe. What bands are you using? Perhpas you can consult with some of the fellows like my friend Dave, G3UUR who is a regular on 160m, 80m, 20m and 10m AM. He is close enough that you ought to be abable to hear each other well. He also knows a number of other active G-stations using AM.
