Hi Ulrich: I think the answer is what other low cost options are available? I would like to have a more modern TIC capability to add to the clock I'm working on. But although there's been a lot of discussion about different ways of making TIC measurements, it's not clear to me how to do it on a budget.
For example the TIC232 circuit by Richard H McCorkle is easy to implement, but how good is it's noise floor. See: http://www.piclist.com/techref/member/RHM-SSS-SC4/TIC232.htm Then there's the low cost frequency counting TIC that appeared in QEX that we know trades performance for low cost so it's not a candidate. Any ideas on what circuits have a noise floor that's compatible with the M12+T or it's newer equivalents and at the same time are in the low cost category?
