Interesting for RF gurus

Reviewer: from Somewhere, USA

Same applies to the base version of this module. Can't find the pinout for this module but it has an SA601 mixer, SA676 FM If/demod and UMA1015 dual PLL inside. Plus the usual assortment of transistors, varactors. Also has a ceramic discriminator and 12.8MHz crystal. Most interesting are a pair of 26.050 2-pole crystal filters. Some variable caps and what looks like a pair of SAW filters. Has potential for wasting a lot of time. Not so sure about using if for a cordless phone but who knows. Lotsa parts inside. I/O via a 2x6 female 2mm header.
