Changed ANTONT=16.5 in locals.dat file (was 0.4 degrees since Nov 1992).
6-11 Feb
Various API experiments and tests using Heater and Dynasonde (Pmodes).
10 Feb (and various days afterwards)
Noticed bad (sticking) relay in attenuator in IF module, channel 2.
16 Feb
Replaced slow attenuator on ch2 (Unit 17). Replaced all 4 relays from a
spare unit.

11 Oct
A unit of 6 fans was installed between receivers 1 and 2 for extra cooling.
They no longer get hot.
13 Oct
Re-configured receiving antenna sampling scheme to Owen Jone's "L-configuration"
to mitigate the effects of the PRE antenna on the N and W antennas. Soundings
are numbered from TR300001.* onwards to distinguish them from the other
soundings.
15 Oct found SMA connector to ADC#3 loose, probably disconnected.
20 Nov
Sounder left in a 2-antenna configuration (s, e) for good polarization
discrimination but no direction of arrival information.
22 Dec
Old Interdata computer removed from rack, PC put in.
