Simple radio project

My original post was banned by the censors as it violated blogger guidelines, probably as the algorithm saw certain words.  Talk about nanny state!! In the gaps, insert letters!

With my own ch***n, I totally failed to get them interested in amateur radio! In 2 weeks time my gran###n is here.  His d*d has asked me to work with him on a radio project.

I have ordered a TA-7642 (ZN414) TRF chip from GQRP club sales, but realise I shall also need a small slab ferrite rod, a high impedance crystal earpiece and a 1.5V battery holder. My building skills are really poor compared with before my stroke: what would have been really easy is now hard.

If I cannot find these parts, I shall have to build an LED signaller instead.

It would be good to see another novice operator. Oh look, there's another flying pig.  😉
