sorry, found the script (yay) but I did not actually implement UTM input, not that this is.
for reference,  Tlafore, the coördinates for this note you left are, in OSM internal format 42.6554875,-73.9324093 (signed decimal degrees north and east.  negative east is also 73 and some degrees west - of, well, london).
Your given 18m05s corresponds to 0,30139° at the end of something, which is far away from here, so it must be a completely different reference, just like the S 57 does not correspond to the UTM grid I expect here (hard to say when my Garmin suffering the 1024-week bug has lost all its maps making panning in other grids or datum more than a bit difficult).
Can you check the coörds again or explain how and where you got them, and if from some handheld device, see if you can get numbers close to those above?  (that is the GPS standard WGS84, though either decimal degrees or some variant of decimal or whole minutes and seconds sees common use)
Thanks!
I ask this on behalf of Constable, a volunteer as myself, more than happy to help if the info is correct and as self-explanatory as possible.
sorry if what i write is too much detail, or greek...
