Give them a couple days for thermal stabilization and I'll check the spectra then.  The HAM5 unit is the one from EndY which was with the BRS that just did not have the quality we wanted.  The HAM5 STS is located in the Bier Garten for huddling with the ITMY STS; it is maybe 2 meters away.  The HAM2 unit never moved, just borrowed the Host Box for a couple weeks.
