I assume you mean a USB to RS232 adaptor which has a DB9 connector. I also
assume you've already got a RS232 to CAT converter for the 847? (I think the
847 users the standard Yaesu round CAT connector).
If the the above is correct, there are loads of cheapies on Ebay for a few
£ but I'd recommend paying a bit extra and going to G4ZLP- a Google will
find his website.
Also, rather than end up with a "daisy chain" of USB>RS232>CAT why not
buy a USB>CAT converter. Price will be about the same and the set up much
neater. I'm pretty sure G4ZLP does those as well.
The issue with the cheapies can be driver support. The cheapie manufacturers
don't always follower the recommendations of the chip manufacturers and the
standard drivers don't always work.

thanks brian,
its a bit of a nightmare, yes i do want to keep it as neat as possible
with as few connections needed.
will go over it all again and see whats best but agree a driverless
solution would be best.
its to run ham radio deluxe.
You will need a driver, the question is finding one that works with your
operating system. What tends to happen at the cheapie end of the market is
that the manufacturers produce a driver for the operating system current at
the time they designed the interface. It may work with later operating
systems but if it doesn't, they don't update it. This happens even if
they've used one of the "big name" chips from a company which has updated
its drivers but the interface manufacturer hasn't followed the
recommendations etc. This is one reason I like G4ZLP- he recognises the
problem and ensures drivers are available on his website. He isn't the
cheapest but the quality and service are good.
I've got some cheapie interfaces as well, it is just a bit of a gamble.
hi brian,
just spotted a serial to usb adaptor on ebay that should do the trick--
it seems to have a better spec than the on i was using--which i dont
think was working properly anyway.
i did check out G4ZLP,s site and his prices are not too bad but would
have to daisy-chain cables and im not too keen on that.
but thanks again for the information provided brian.
The troublt with the 847 is that it's a null modem cable it requires.
Of course, the proper solution is to use a real computer, instead of a
netbook. Then you'd have a real serial port, and wouldn't have to spend
forever trying to find a USB to serial adaptor that actually works.
Nope, the 847 is the redheaded step-child of all rigs when it comes
to CAT. It has a standard RS232 port for CAT. No level converters
needed
It's actually a 3 wire serial port, so you need to make sure stuff
like hardware flow control is off.
2M0SIL, I would suggest a 9pin-9pin RS232 Null MODEM cable, and then
into your RS232-USB converter (most USB-RS232 converters are wired
as DTE rather than DCE)

PS, remember...two Null MODEM devices (cable *OR* box *OR* USB<->RS232
wired that way) make a MODEM (ie straight through) cable...A trick I've
used many a time

I must confess I've always been pretty lucky with all the RS232<->USB
converters I've used, all have supported all lines, and not just been
a 3-wire serial port
Then again, I've often been after 4 or even 8 ports, so they are not
shall we say the cheapest available.
However, if you have a free PCI slot there is always something like
this: http://linitx.com/viewproduct.php?prodid=11850
Ignore the fact it's a linux shop, it's essentially 6 *real* RS232 ports
on a PCI card, with 16550 UARTs, it'll work on pretty much any O/S

Never had a problem with FTDI's USB<>RS232 devices or drivers. But as
they're Scottish and not Chinese it's hardly surprising their stuff
works. ;-)

From experience, I wouldn't deal with G4ZLP. IMHO, a dodgy character.
Nothing a 2 port serial PCI card can't fix.
Oh, a useful thing to know. Thank you.
What OS does your netbook run? Check with the manufacturer of the CAT to USB
converter first to see if they supply a USB driver for that particular
operating system. Some of the cheaper netbooks run windows CE which is a bit
long in the tooth so developers don't bother with it.

check with the seller that the deal includes driver software for the
operating system of your network. - thats probably why your current one
isn't working.

Then it's not a PC.
A PC needs PCI and PCI-Express slots.
Anything less is just a Netbook in drag.
I have no problems with the Prolific chipset units and have two usb to
serial converters plus a USB to CAT interface for the FT857 (also
Prolific chipset)and two standard serial ports used for the FT1000MP CAT
interface and computer controlled rotator all running at the same time.
And yes they are all Chinese not Scottish!
Surely after your recent blurting out of silly childish remarks (as is your
wont)
directed to me about homebrew, you don't go out and buy things as
simple as cables off the shelf?
Sheesh!
Talk about the hypocrisy of the representatives of the RSCB who
post into this NG!
Hence why I build my own.
Claiming to be building your own motherboards will bring
Mrs.Confabulation down on your shoulders!
I meant build my own PCs, that way I get to choose how many PCI slots
and what's in them.
one of the best radios on the market for price . more people bought
these radios and hold on to them ,than anyonther kind , what does that
tell you about them
>In the "good old days", I would never buy a motherboard with less than

In the "good old days", I would never buy a motherboard with less than
six ISA slots.
In the good old days, the slots on the Unibus and Omnibus WERE the
motherboard!
Nah FT-2000 Shirley!
Overrated and over priced, like most other new rigs these days.
Find a good used FT990 or TS950, spend the difference on a good aerial
setup, and your money would go further (literally).
LOL!
I've still got a few ISA cards here.
theirs is a lot of spec for your spend , i wouldnt mind a got at one
always been one of those radios a looked at in a book and thought i
would like that , saw it back in the late 90's with matching psu,atu ,
md100 and rotater in a PW mag , and loved it even since if looks
could kill . and its a pretty good recever too
a would have a ft1000d,1000mp or 1000hp mk5 field over your pair . any
day , in fact a would prob take an ft847 before them pair . lol
thanks to all who replied to my question--mostly.
some good information to digest--will let you all know how i get on.
thanks.
Either of those two will blow holes in an 847, perform as near as dammit
on a par with the FT1000, and you can get one of each for the same money
you'd pay for an FT1000.
Like I said, spend the diff on a good aerial and you won't regret it.
you mean one like yours tee hee ......
CP-6 FROM DIAMOND you wont go wrong
I think you can .....
Does the job like no linear ever could.
