Re: S-85 refurbish: I've got a problem during the RF alignment of bands 1 and 2 - trimcaps don't peak!
开云体育Emanuele, we are happy to see your success so far! We wonder firstly if band 1 and 2 work = bring in stations at all? It seems strange that 2 bands have the same symptoms, and they are in the first RF and the second RF tuning; in total 4 wonky circuits all acting the same way. ?? Could you have unintentionally moved the bandspread to counterclockwise ??before doing 2, and 1 ? Also, it is sometimes possible to accidentally tune onto image frequency and get trapped on the image frequency rather than the desired one. From the ranges I think the images should all be above the desired frequency by 910 Kc/s. If it is accidentally ?near the image now, I am wondering if you begin again on these bands with the cap fully in maybe it will latch onto the desired frequency first. There must be a better way to state all that stuff, but it is a thought. ? From: [email protected] [mailto:[email protected]] On Behalf Of Emanuele Girlando via groups.io
