The SBAS test transmission services
The test transmission services has been extended and will be available until 31 July 2020. This will provide continuity of SBAS signals to support R&D, industry testing and encourage early adoption.

and it seems that some existing units can be used to receive this test signal:

Can my existing WAAS/EGNOS enabled receiver be used with the new SBAS services?
For the L1 legacy service existing SBAS-capable equipment can be used, however a firmware upgrade might be required.

Question: Does anyone know if either or both of the Garmin Oregon 600 and eTrex 10 are capable of receiving and utilising this signal?

Both units are WAAS/EGNOS capable, and I have the latest firmware in each.

If they are capable in this area, I assume that WAAS/EGNOS would need to be "On" in the unit, or would a separate SBAS menu option need to be available? (which it isn't after the latest firmware update)
