Further details:
The builder claims the power is "about" 250 mW at the antenna, no other details on the transmitter. Antenna is said to be a hidden inverted V running N/S with good take off to the West, and obstruction to the East. Dit rate is now 60 dits/sec (I saw it at that rate this morning). The location is either in the Panamint Mountains on the West side of Death Valley or in Panamint Valley itself, as the emails just say "Panamint". The description of the antenna would suggest the West side of the Panamint range, but that is a guess.
The builder does not appear to be a poster here, but might be reading some of the threads. After his initial email to me (a couple of months back when the ditter was on 5711.8 kHz) I mentioned this site and his last email referenced the ditter having been heard.
