color=#0000ff size=2>I have a Panasonic W1 VHS machine that will play any
standard - did a stack of Ken Copeland tapes for our local Church. It will also
do an "EE" conversion. Of course, most of our stuff here in Oz is NTSC to Pal.It
is what I would call as lo-Pro machine, with no inbuilt tuner but fitted with
IEC power socket etc etc. That said, it does a great job of conversion with
clean burst blanking etc on a WFM. They come up occasionally on Ebay. This one
is from an Ad agency. It has selector buttons on the front panel for the direct
mode, with slide switches behind a panel for recording mode
etc,</FONT></SPAN></DIV>

<DIV><FONT face=Arial>I was considering their NTSC> PAL standards converter
for some basic conversion from an NTSC s-video camera signal to a PAL
system.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>However, seeing that its in the somewhat lower end of the
market i wondered how well it performed this conversion as if it introduced
dropped frames as its method of conversion resulting in jerky video</FONT></DIV>
<DIV><FONT face=Arial>then it would not be suitable for the job, emailing them
to see if they had a demo video or could explain what method it uses to convert,
they couldnt answer</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Perhaps someone could reccomend a decent but lowest priced
converter that does the job without noticable dropped frames or jerky
motion</FONT></DIV>

<DIV>Hi folks</DIV>
<DIV> </DIV>
<DIV>Attached are pics of both sides of the (rather nice) PCB for this
eBay.co.uk-sourced SB-3680 RGB-to-CVBS, Y/C converter (serial:
20048001106).</DIV>
<DIV> </DIV>
<DIV>It uses a KA2198BD encoder chip wired for PAL operation (pin 7 grounded)
and a 4.43MHz crystal oscillator employing a Schmitt-trigger inverter.</DIV>
<DIV> </DIV>
<DIV>Inspection reveals that R1 and C5 are not fitted, which means the 4.43MHz
subcarrier is not reaching pin 6 of the KA2198BD b so no wonder I am having
problems with the chroma output.</DIV>
<DIV> </DIV>
<DIV>Also, the KA2198BD datasheet says that for PAL the components connected
to pin 17 should be 82uH and 15pF whereas 100uH and an unmarked capacitor are
actually fitted; if the capacitor is 20pF, these values are what the datasheet
says should be fitted for NTSC operation.</DIV>
<DIV> </DIV>
<DIV>Weird.</DIV>
<DIV> </DIV>
<DIV>eBay seller swears blind it was working ok but decided not to return as
paid next-to-nothing for it and was curious to get to the root of the
problem. Ibve e-mailed Shinybow in Taiwan.</DIV>
