Having searched Amazon and eBay for a “complete Pi package” - It seems a self assembly package (put the parts in a supplied pre-cut box) costs at least €80 plus for a display at least another €40-70 (depending upon size) - to house the display a different box is then needed adding more cost up to €50.
For what I expected to be a cheap computer, it seems the Rasrberry Pi board itself is “reasonable” at about €30 but with all the other pieces needed the solution (still needing some assembly work) comes to a price close to a fully built cheap Windows 7" tablet!
Even leaving the display out and using a smartphone instead the price is higher than I had expected. Having tried to use a smartphone to run PSK31 from a SOTA summit, the readability of that solution doesn’t appeal to me albeit smartphones now can have larger displays that when I last tried it 5 years ago.
It seems a Windows tablet remains the most practical solution to run FT8 from a summit.
P.S. Just found this video on the DRAWS Raspberry Pi hat - it’s certainly not going to reduce the overall price of a raspberry Pi based solution - rather the contrary but if what the video “supposes” about the product is correct, it will simplify alot of the ancillary equipment that is needed.
