hi Hans, the message was not referring to you and your company, you are a person to be admired, you manage your whole company together with your family to give many radio amateurs all over the world

I read that same article last night! :D

Hello Giuseppe I'm sorry for the problems with a percentage of the power boards. I believe it to be a small proportion, I have been collecting statistics here on our assembled boards. I have so far

OK, some weeks later and a few issues with my GPS receiver and aerials, I have tied together the OSC5A vctcxo with the NB3N502 and a Progrock v1. ( I have no doubt the v2 Progrock will suffice, but
