[Premium-Rx] Shortwave receiver EN-R2, Intermarine Electronics Inc.

[Heinz Breuer]

Hello Steve,
no internally the EN-R2 is totally different. The EN-R2 has a power supply on the left and a couple large plug-in boards with a motherboard underneath.

I am on the road to pick up more stuff over the weekend and will take pictures of the EN-R2 innards next week.

There is an empty spot for a sixth filter but the front panel has only 4 push buttons to select filters which are labeled VNAR, NAR, INTR, LSB (very narrow, narrow, intermediate and LSB. If no push botton is pressed the USB filter is selected.
