155.340 has been a longtime EMS to Hospital freq. and is still used in many area's. Thats not saying that things arent different in your area. Is there no listing in the database for your area? If not give that a try. Some squads use cell phones or local TRS for there hospital comms, others may still use a telemetry radio. Good Scannin Hoser
nyyanx18, since this is the DC forum, I'll assume that you are asking about the District, and let you know we do not use HEAR (155.340). The DC hospital communications occur on the 800mhz digital trunked system listed in the database here: http://www.radioreference.com/apps/db/?sid=234 Other than that, you can also hear some Maryland and Virginia hospital comms on the UHF MED channels, which are still patched to the systems around here.
