An IC-729 mod : From original two FET mixer to a FET ring doubl balanced mixer

Imahe
Ages ago I had a chance to service an FT-1000 which belonged to an American ham. I was impressed with the radio and in the course of the service I got to read the schematic and focused on the first mixer.  I noticed the difference between it and my old IC-729 was it had parralled FETs in the mixer so instead of just two (see IC-729 mixer circuit in the photo), The FT-1000 had a total of four which accounts for its signal handling capability. On a lark, I set out and bought s ome FETS and thought I would try out the mod. Just before I started construction, I consulted my CQ ferrite core handbook (in Japanese) and saw a circuit for a FET double balanced mixer which promised good strong signal performance as well as gain over the standard diode ring double balanced mixers I have used before in my projects. The only additional part I had to "make" was another transformer for one port. Please see big photo. The four FETs I bought were metal cased. The mod is not too prett...

"Despair of Judas"

It was my first time to join one and Mr. Santos, our class adviser did a good job training me at the house of Manolito Cua in Sto. Nino. I remember his tip: if you do not know how to fake a crazy laugh, just gasp! It seems just like yesterday. This was my piece: "I will rest here, awhile. His face! His face! Not comely now. There is no beauty in it. It is scarre d into my heart. It is burned into my soul and never will it lift from me until I die. Die? Will death quench the flames which consume me? Traitor, not endless years in hell can even pay the crime of murdering the son of God. And last night, he dealt with me so gently. He washed my feet. He bade me to put my hand into the cup with his, while in my purse there jingled the coins which bought his blood. It was better ...
