Thanks for the contribution - much appreciated. I've merged your PR into RC 1.2.30. There is already a test of MON-RF parsing in test_stream.py (testMONLOG) but unfortunately it contains a jammingState value of 0 so didn't show up the issue.

I note also that the attribute currently defined as jamInd is referred to as cwSuppression in later versions, but I'll retain the existing name to minimise regression impact.

If you happen to have a real raw binary datastream containing a UBX MON-RF with a jammingState > 1, I'd be grateful if you could send me it and I'll add it to the test scripts - otherwise I can synthesize one. Thanks.
