XV144 ATF34143 phemt equivalent

[Chris Reed]

Hi all,
The ATF34143 Phemt used on the rx input is discontinued and I just wondered what the suggested replacement would be for this little gremlin. I've Just purchased a second hand XV144 and I'm not getting any variation when I adjust c1 and it looks like the 34143 has already been changed looking at the state of the solder.
Any guidance would be much appreciated.

I'd try a PGA-103+ as a retrofit... plenty of them around.

Chris,

Have you tried ordering the part from Elecraft?  I am assuming they
still have some in stock.  Email to [hidden email] with the part
number and description and you should receive a return email with the
cost.  That will allow you to use the Quick Order form on the website to
order and complete the purchase.

Hi Don,
I had thought about it, but it's a long way to send it and figured i should be able to find something more local.
The Doc's suggested an equivalent which I can get ( I'll get a few just in case), so will give it a go and see if fixes it. It certainly down on sensitivity, my IC7400 is better on 2m at the moment.
Thank you for the quick response, very much appreciated.
