Hi all

 

John sent me over this sketch of how best to interface my= 706 to a Hafler audio amp as well as some schematics from their excellent w= ebsite on the subject

 

http://www.w1= vd.com/page21.html

I have a 3000, though John informs me that these don't pl= ay nice on 472.

 

I've got the coax and the -77 material cores and caps so i= t's time to get building.

 

I'm on the lookout for a 9505 but most on Ebay  are o= utside my budget and also US spec and need 110V, though I could always get a= converter.

 

If the weather stays dry, then I'm hoping to crack on wit= h this, this week and get G7NKS to be a bit more QRO and hopefully crack the= T/A and 2000km barriers on WSPR 472.

 

That'll be the broadband gone then!   Stefan he= lpfully sent me over some ideas to look for how to proof the router against i= nterference, but it may well just be a cheapo BT Homehub 4 and it=E2=80=99s internal aerials.

 

Enjoy the darker months guys and hope to see you all on M= F and LF

 

 

 

With best regards

 

 

Jim
