I don't think so, I believe the 4 MPN3404s that you located are used for band switching. They are VHF switching diodes, not varactor tuning diodes.

Well yes they are and the others in there are 3 leg transistors there is nothing else. These varicaps were explained in the thread I read from England so I hope I find a bad one . I seen listings calling then varicaps as well as varactors also.
