Well, I called "CQ" this evening on/about 7.295 and enjoyed a couple QSOs. Yes, still having to deal with the typical 40 meter summertime QRN, but not giving up on the band. I'll continue to call "CQ" and hopefully reel in a station or two. Please listen for me about 2300-0100 UTC around 7.290/295. Thanks much, Will KF4IZE

How about trying to get some AM activity on frequencies below 7200kcs.  There seems to be plenty of room.  At one time 7160 seemed to be mentioned.  I think for AM after sunset, it would be best to establish a frequency below 7200kcs.

That would be swell as there is still a fair amount of foreign broadcast at 7.290 and above. We'll give it a try below 7.200 sometime. Appreciate the suggestion.

I agree.  But we have to establish a frequency.  I was looking this afternoon & 7166 was very clear.  But we have to begin using it (or some other freq) so others know in advance it's an AM freq.

I have been operating in the afternoon between 7280 and 7295 .  the usual suspects are in Calif, Ariz, N Mex. Utah, Colo, Idaho but I sometimes hear the midwest and the East side too...By late afternoon I have to dodge a few SW BC carriers, but I usually find a spot in between them to call CQ..

I think 7190 might've seen some use a few years ago. The transmitter I've been using on the air the past few months is crystal controlled, a 3595 crystal will double and put you on 7190, the only other crystal i have that will get me on the general class phone portion of 40 is 7275, which also is in use by a broadcaster most of the afternoon. If only i upgraded to extra then i could put my 3580 crystal to use, which i could double to 7160. 40 is a great low power band, this transmitter only does about 25 watts there, but of course i don't have crystals that cover where everyone is at.

I had the same problem with my Philips transmitter SFZ395. A VFO build around one of those cheap Chinese DDS modules did solve that...
