 +** Connecting it All Up **
 +
 +Due to the complexity of the system, it is better to show the connections between the various parts by type. These are: RF Connections, Sequencer Control, and Software Links. I do not claim any originality in the way my system is connected, but it probably reflects many others. I know that the sequencer control is very close to that used by Dave G0LBK although the hardware used is substantially different.

-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 April 2025 I had worked 154 unique stations off the moon (known as initials), in all continents, in 115 grids, and in 39 DXCC entities. I think I have worked 15 US states.+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.

 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. 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 order to hedge my bets, I have bought a 250W amplifier pallet for 13cms, and once built, and added a suitable dish feed and low noise amplifier, I should be able to be active on 13cms EME. I also bought a Pluto Plus as a suitable SDR for use on 13cms so I could keep using the QMAP program for spotting stations.
