Simple TSA5511 schematic

Everything technical about radio can be discussed here, whether it's transmitting or receiving. Guides, charts, diagrams, etc. are all welcome.

"Piratenpraten" is Dutch. It means "pirate talk"

Tot ziens!

nice to know
tot ziens = Until I see you, could be whenever. slightly formal.

tot gauw and tot snel are roughly equivalent I believe, though tot snel is more common = see you next time (could be up to a couple of months)

tot straks = later that day (would sound weird if used to refer to a time not the same day)

tot zo = in a few minutes (like if you could bump into them at work)

not sure where tot binnenkort fits in.

"Tot straks" is "see you soon", but seldom used these days, it seems. Dutch is a really rapidly changing language. I'm told by my youthful friends that I sound "antiquated" (ouderwets)!

Tot Mandag - amongst the last things I'd say to my colleagues on Friday afternoon (I worked in Holland for a couple of years).
Come to think of it, in the company I worked for at least, they'd wheel a trolley full of beer around on Friday afternoons and we'd all be invited to have a "borreltje" (a "little drink"). You don't get that in England these days do you!! :)
He said shuffy! I said WOT? Woo!

This PLL schematic.

My favoured approach is to "sniff" the Band II signal and feed that to the PLL from a later stage (where there's signal to spare) rather than risk unbalancing the oscillator. I found (for my cheap PLLs) that the 74F74 would easily clock at >120 MHz, so used this to "pre-scale" the Band II signal (dividing by 4) to feed the 74HC4040 diode-programmed frequency divider. The reference was a 74HC4060, which was programmed to allow the use of the cheap 4MHz crystals, and allow 100 kHz steps up the band. My phase comparator used a 74HC74 and 74HC00, feeding a low noise dual op-amp to give the loop filter, which works much better than the 4046, and gives clear "locked" and "unlocked" outputs.

Regards,
Marcel
