One year had passed, and the SLAMS team was once again gearing up for another ARRL VHF Contest. The calendar read "June 2023" and the thermometer soared past 90F ....
But no, we can't start the story like this, even though it is true. In reality, the preparations began months in advance, and we even conducted a testing event just one week before the VHF contest. Harry WA0NCS built a new station based on the famous SDR Pluto. The design is called "Project Langstone" and Harry used a Raspberry Pi instead of a laptop with Windows to control the unit. Herbert AF4JF got a new set of transverters from a Bulgarian company SG Labs with decent PA units for 902, 1296 and 2304 MHz. Herbert and Harry tested these new units on Saturday, June 3. AF4JF went to Cottleville Community College in EM48qs while Harry was at High Ridge in EM48rl. The distance between these was about 20 miles.

After the hamfest, we all headed to our usual lunch spot - Uncle Linny's restaurant in Pontoon Beach. They serve fantastic burgers in sizes of 1lb, 2lbs or 3.75lbs.
