OFF AIR but hope to be back by 1115z Saturday morning if I don't oversleep

Low activity due to ARRL Field Day hang over probably for the best with wide ranging storms generating QRN

– Posted in: 630 Meter Daily Reports, 630 Meters

This session was down to a “skeleton crew” as people convalesce after ARRL Field Day weekend.  A massive storm system from the Southwest through the Midwest also made it a very noisy night.  While we had experienced early renewed activity prior to this weekend we may see a bit of a back slide through July 4 as many people travel for Summer vacation.  I am sure many of us will keep signals on the air and just fight through whatever we are dealt.  This is potentially a stormy week in North Texas.

Geomagnetic activity has been quiet with an excursion to unsettled levels during one reporting period.  The Bz has been pointing to the South and the solar wind velocity is above 450 km/s with periods above 500 km/s:

Jim, W5EST, presents the following tidbit that was presented to him by Ken, SWL-EN61, in Indiana, entitled, “RECEIVE 630M WITH ASUS TABLET USING ELAD SDR”:

“Ken SWL/K9 e-mailed that his Asus tablet (T100TA)* runs Windows 10 and receives 630m using an Elad FDM-S2 sdr.**
HDSDR software on the tablet supports the sdr hardware http://www.hdsdr.de/ . WSJT-X on the tablet decodes the resulting audio of WSPR and other digital modes.

The sdr/tablet grounds are connected together and to the third wire ground at the receptacle. The receptacle feeds the tablet power supply. The tablet powers the sdr via USB.

The switching power supply for the tablet has only a two-wire plug… hot and neutral, no ground. So, for grounding, a special 120v ac plug only has the ground connected, not the hot and neutral wires, and brings out the third wire ground. This 3 prong plug for a ground plugs into the wall socket in addition to the plug for the tablet PS. The hot and neutral blades of this plug have no wiring attached to them. A 4 foot #14 solid jumper wire with alligator clips on both ends completes this ground connection. One clip goes to the #14 solid wire from the plug. The other end with the jumper connects directly to the sdr/tablet ground.”
