-By the next night I had replaced the pre-amplifier with the lower noise one, and proceeded to work a total of 65 unique stations in my first week of operation with my compromised system. For the next period of operation I had replaced the dish feed with my Septum Feed and slowly increased my power to 300W or so. By March 2025 I had worked 133 unique stations off the moon, in all continents, in 102 grids, and in 37 DXCC entities. I think I have worked 15 US states.

 WSJT-X incorporates an Echo mode which transmits short pulses and detects the echo, and I can usually see returns of around -19dB (in a 3kHz bandwidth) which is more than enough to be able to work myself, if that were possible. Indeed I have worked many people running systems similar or smaller than mine. The smallest station that I have worked is G0HIK with two 33 element yagis, OE3JPC who uses two 56 element yagis is also regularly worked when the path loss is low.

 A potential problem is the results of WRC-23 which may have a huge impact on EME operation on 23cms, but at this time no-one knows for sure what it may be. In the extreme case I, and many others, may have to pack up on 23cms and look at getting going onto 13cms. This wouldn't be the most difficult change, the IC-905 can easily accommodate it, and the sequencer and relays would operate on 13cms without modification, but it would be an unwelcome termination of activity on 23cms, a band I have been active on since 1985.
