Mark I looked at the 7 and the pulse out wasn't obvious. Indeed at that cost it would be great if it did produce 60 KHz as it would eliminate the whole counter chain + power. The chronverter wants GPS data so its a nice answer. I have some 6s here so will start with that. Love low power and crazy cheap technology. Regards Paul. WB8TSL
