RF prototype boards arrived today from JLCPCB. The service was, as always, very fast and flawless. Seems they have a direct arrangements with Customs because I was not required to pay anything.
I ordered 100 pcs for a total amount of 157 euros, apx 1.57 euro per piece. This includes manufacturing and shipment via DHL. These are intended to accompany QSLs that I send to some very special ham contacts but also as gift for my friends, especially for those hams that I know are enthusiast and prolific builders and experimenters.
