First building projects for the new shack

It will take a few weeks to settle into the new home and get things straight, but already my mind is turning to projects for the autumn. Several of these are hang-overs from the current QTH i.e. "gunner" projects (I'm gunner do this or that!) or projects already started but needing to be completed. This is the list so far. You can be 100% certain this list will grow and change.
  1. Check the LF/MF/HF noise environment at the new QTH. I have no real idea how this will be. I am more in the middle of the village at the new QTH, so suspect switchmode PSU and other noise sources may be more of an issue?
  2. Finish the 10m WISPY transceiver. Both the direct conversion RX and DSB TX have been built and successfully used on air, but I have still to put the 2 bits together as one transceiver in a box.
  3. Finish the optics for my G4HJW designed Finningley optical transceiver. I finished the electronics build some weeks ago but the move got in the way of the mechanical parts. I need a new stable tripod for this too.
  4. Carry out some VLF earth-mode tests at 8.97kHz from the new QTH to compare results after the QTH move. My baseline earth-electrode "antenna" will be very slightly shorter and the direction more NW-SE (it was E-W before).
  5. Carry out some 472 and 136kHz WSPR tests using the earth-electrode antenna. Again, the aim is to see how results compare at the new QTH. The earth-electrode's new loop direction will affect who can copy me.
Whether I concentrate on HF/MF/LF or move more to VHF/UHF will depend on the noise environment. Although there are plenty of things to try to reduce QRM if this proves to be a problem, it may be the perfect excuse to try something new, such as weak signal QRP work at VHF and UHF. We'll soon know.

how about a wspr transceiver?

Anyway, a good job!
