Annual Field Day Special Edition

Travelogue:   To the Dominican Republic! 

New dog -- Meet Guapo (see below). 

A great Father's Day for Pete and Bill.  I got a TinySA. 

Pete got some cool chick magnet glasses (see below).  

Watch out Newbury Park! 

Bill's Activity

SST Transceiver. Took it to Dominican Republic.

Made only one contact, but QRP-QRP. 

Not a lot of CW activity, and not a lot around 14.060. 

A lot more FT8 visible on the NA5B WebSDR.

That might be better for this kind of operation.  

I might try SST CW out today from the backyard. Field Day!

Fired up my 20 meter DSB NE602 rigs.  Made two contacts.  

Still trying to fully understand the NE602 Gilbert Cell.  Lots of mystery in there. 

Building "The MythBuster."  75/20 with sideband inversion.  

10 pole 5.2 MHz filter.  Used Dishal and AADE. 

Used NanoVNA to see the passband. 

G3UUR for crystal parameters.

Cohn Constant K topology. 

Also used NanoVNA to check input and output impedance on the TIA amps I will use around the filter. 

Pete's activity: 

Article on DC receiver in SPRAT. FB response. 50 receivers under construction.   

Work on Drake A Line.  

Jim Spillsbury.
