08:10 AM mun: anyone know of any good high-res camera modules? around 16MP?
02:04 PM rue_mohr: polprog,
02:04 PM rue_mohr: it could be silicon failure, which caps are electrolytic?
02:04 PM rue_mohr: or, thats a photo of them isn't it?
02:19 PM polprog: hmm. I dont know. I managed to get the pll to lock
02:19 PM polprog: Ill be probably checking the caps later
02:19 PM polprog: id like at least 100MHz of bandwidth
03:13 PM polprog: so far i have the PLL tuned at around 446MHz... now ill have to tune the filters and maybe TX power
03:13 PM polprog: although the TX connector is disconnected for now
03:15 PM polprog: rue_mohr: yeah the image in the tweet is the RF board
03:17 PM polprog: weve got 15MHz of PLL bandwidth now
03:18 PM polprog: these muppets did not put any values on some of the parts
03:18 PM polprog: on the schem
03:18 PM polprog: becuase the radio comes with so much different ranges and models
03:19 PM polprog: the good news is that, thanks to this it should be relatively easy to retune... i need to look for the guy i bought this one from
03:23 PM polprog: i reckon that if i replaced the cap and the inductor with similar in ratio, but smaller in value parts, the varicaps that are used to bias the VCO would have more "power"
03:23 PM polprog: because that 15MHz is really hitting the control voltage limit
