So, you got caught up thinking hey I could build a SSB Jr. Well, pilgrim think twice as the trick pony is the phase shift network. Back in the day you could just buy one from Barker and Williamson the Model 350 known as the type 2Q4.
They can be found on eBay but hold on to your butt -- this one cost $100.
You would be better served by researching the work of Rick Campbell, KK7B who designed the R2 and T2 which are phasing type receiver and transmitter boards. Campbell used operational amplifiers coupled with precision capacitors and resistors in his design. Components to build a complete rig based on his design can be had for the cost of the 2Q4.
When it rains it pours. I did build the IRF510 RF Linear amp and as I predicted about 4 watts to a dummy load. That said there is now some sort of anomaly on the receive side -- a perfect definition of SNAFU. Well, it does keep me out of the bars and/or getting into all sorts of trouble.
I am attending a Grief Group and the group leader in the last session was adamant: Don't take any sort of major action for the next 12 months -- you know selling your home, moving to Tahiti or hooking up with a 45-year-old divorced mother of two teenage sons.
I suspect purchasing a FLEX 6700 would also fall on the counselors list. But somehow an 82-inch wall mounted LED monitor along with the FLEX6700 and a 1500-watt legal limit amp is making a significant statement about your station!
Them that know can make it go.
