Late last night I got round to connecting the Garmin GPS18x-LVC and just after midnight it stepped from around 60s to 0.5ms and 8 hours later is between -74us and +62us. The module is in south facing upstairs window in same location I failed to get anything useful from the Globalsat BR304. Now I need to make a 30m extender cable to get the signals downstairs to back of house to connect to servers.
