    TRS92 Antenna switch

    Hallo! Interesting that both cracked ferrite, maybe it got too high a frequency? I have the full description but unfortunately the type of ferrite is not in it so I can rewind. This is the total in my book:

    TRS92 Antenna switch

    Hi, is it normal that both ferrits are broken? Or is it intentionally not a closed circle?

    TRS92 Antenna switch

    Hi! An interesting thing I got today is an antenna transmit / receive switch manufactured by SRT. I got the full Hungarian description, does anyone use one? Is it worth dealing with? I wonder how good construction, 400watt I don't want cooking in the receiver. Thanks !!

    SSA400 Driver module 2 problem

    Hi! I made a drawing so it's simpler, unfortunately the compiler is quite interesting. I just want to ask, do I understand the drawing well? Thanks!

    SSA400 Driver module 2 problem

    Hi! I measured all the points, and by the end it turned out that the connector was numbered inside ....... :oops: I connected the two points you suggested, but unfortunately nothing has changed, I'm starting to give up .... I could use it so that UD2 keeps going, but it's not intended to be...

    SSA400 Driver module 2 problem

    Unfortunately, my B10812 3110 motherboard doesn't match either, according to the drawing, the sign comes at point 43, there is nothing connected to me in the picture.

    SSA400 Driver module 2 problem

    Hi, the problem with me is the foot layout is different, it's marked with letters, not numbers. Here is a picture of my motherboard, you can switch whether this tuner is present or not. And some delay, regardless, can be connected to the tuner connector .... Tuner connector:

    SSA400 Driver module 2 problem

    Thanks! If I have to disassemble it again for exercise .... :) It's huge, it's not easy to assemble on its own, it would be good if it works fine because the UD2 is warming up enough. I have noticed that the input of the prorgam module is routed to the tuner connector, if I pull it to the...

    SSA400 Driver module 2 problem

    Hi! Today I disassembled the unit I wrote in the picture is correct, at point 24 it was +4.4 if I press CW it drops to 0v. I measured the entire connecting cable all the way through, everything is faultless. But I don't have a tuner, did I hear you have to tie something up like that? I noticed...

    SSA400 Driver module 2 problem

    Hi! I took out the TD90 book, do I understand that the driver also gives a transmit signal to the amplifier? The RF LED on the connection cable on the front panel also flashes, showing the output power level. Is it possible that the connecting cable is damaged?

    SSA400 Driver module 2 problem

    I found an old repair to the very transistor that the pin leads to, unfortunately good by measurement. In the drawing, which pin is where the signal comes from if there is a TX?

    SSA400 Driver module 2 problem

    I did the following, a cable is soldered to point 4 above, I connected it to the ground through a potentiometer during operation. See the miracle the two modules come to life, all values are fine, the output power according to the instrument is 80. The lamp in the room flashes as I press the CW...

    SSA400 Driver module 2 problem

    Point 4 of the drawing, which is connected to R11, I soldered a wire to it. I measured voltage, 45 was there constantly this normal?

    SSA400 Driver module 2 problem

    Hi! I measured all the parts on the PCB and found no faults. I will try to deduce the P1 6 point as shown in the drawing and measure what you wrote during operation.

    SSA400 Driver module 2 problem

    Hi! I have an SSA400 amplifier that I turned on yesterday. The drive is a TD90, perfect for communication with the amplifier. I put a 50ohm dummy load on the amplifier, a TD90 got a A1 press CW and checked the instrument at the front of the amplifier. On the UD1, the trimmers that controlled...
