Nice Meteor M2-4 pass this afternoon on the equinox. SatDump with our 1m dish at EM00. Radio N5ZXO and N5ZKK.

@RFconsultantUK Our neighbor donated an old TV mast and my wife is N5ZXO so no troubles here.

Strange problem with my Vitality GOES station this past week. Pre-amp failed, replaced, worked until sunset and the VIT went thru the roof. I thought the sun must be the issue (Vernal Equinox occurs at 14:45 UT on March 20th) but it ended up being the COAX. Bad Coax.

Added some aluminum mesh while troubleshooting as I thought another DB or more would help. Now getting a super good signal from this small mesh dish in the heat of the day. VIT is in the 200's.

@USN_Submariner It was a training mission to test the new methods of long term storage for steak and lobster.

March 20, a cursed day for submarines...
OTD in 1993: US Navy Sturgeon-class boat USS Grayling (SSN 646) just coincidentally happened to be in the same location in the Barents Sea as Delta IV class submarine RFS Novomoskovsk (K-407) and put a little ding in the Russian SSBN.

OTD in 2009: USS Hartford (SSN 768) pulling into Bahrain after rolling 85° while running up under the keel of USS New Orleans (LPD-18) while at periscope depth in the Strait of Hormuz. Had to transit all the way back to the US on the surface for the $120 million repairs.

@johnkonrad Salt water will finish them off. Better go with the tail hook option.

@loebl_tom 1700Mhz. VHF is very noisy and takes a lot of effort to keep the household clean.

@david_trolinger is this on 137.9 or L band? What kind of antenna are you using? I'm just about to give up on reception.

Meteor M2-4 this afternoon at a clear springtime day here in Kerrville, EM00.

Meteor M2-4 today at EM00 with maybe random cell phone interference on the horizons and a couple of places during the pass.
