Thank you all for the information!
I initially built the kit using the supplied parts. In troubleshooting its lower output I made a few modifications...
When I rewound T1, the output transformer, I used 24 gauge wire for the secondary, but kept 22g for the primary. I thought it might reduce any negative capacitive coupling within the transformer. It didn't seem to make much if any difference.
I rewound the 2 of the 3 LPF also using 24g wire. I wanted to make it easier to compress/expand the windings. Again, not much improvement.
I'm using SIP sockets for the BS-170s. Mill-Max brand, Mouser??I've found the to be better than the generic one's I'd used on a series 4 QDX-LB. These are 14-pin strips that I cut down to two 6x1s and were more cost effective, IMO.
Again, it's a 9V build that I mainly use now on WSPR running at 7.49V and draws ~700mA in transmit on 10m.
Any thoughts about using Type 61 mix for the binocular core?
Thanks again!
