Just discover you can VHF (144-148 MHz) support for ZUMSpot by an external 18 nH inductor between L1 and L2 pins of ADF7021. This will enable dual band (VHF/UHF) operation.
How to Identify a Genuine MMDVM HS Hat by florian Wolters.
To help distinguish between an orginal #MMDVM_HS_Hat and a clone have a look at the two pics below. The first one is an original board revision 1.2 manufactured by us. It has the name “MMDVM_HS_Hat” on it in the upper right part. The silkscreen is properly placed and our callsigns are clearly readable. In addition to that there is the Open Source Hardware (OSHW) logo on the lower left.

The next picture shows the clone. It is only revision 1.1 and has misplaced silkscreen in the area of our callsings. The OSHW logo was removed as well as the “_HS” suffix on the name. Secondly it seems as if the RF parts are of poor quality. The picture is courtesy of Lindsay, VK2AMV.
Case was the recommended for the #MMDVM_HS_HAT. Antenna is a Retevis soft antenna, selected because it was short and weight was at the bottom for stability.
