I have finished some maint. on my 2m eme station and have the array
back up for use.
I decided to remove my secondary TR relays (HP8765A) from the system
as the NARDA relays test >100 dB isolation. I kept the
double-shielded RG142 coax jumpers from the preamps to the TR relay
and continue to use RG-58 for dc supply (to avoid RF pickup on the
preamp power leads).
The other reason to remove the HP relays is their possible use for
3400-MHz (eme).
Progress continues on the 1296-eme system: I rebuilt my LNA into a
new larger enclosure with seals at the coax connectors. Also allows
me to add a second LNA to buffer gain needed for running MAP65.
The driver remains to be installed and final Tx tests. LNA need to
be reinstalled (15-min job). And one wheel replaced on the azimuth carriage.
I may be QRV on 2m around MR (2300utc Feb.28); check N0UK logger EME-1 for me.
