I find these 6 MOSFET's functions on PCB(P/N 08-00662.001 Rev.0)
These 6 MOSFET sets 6 voltages with 5 trimpots..
It's a +24V,, +5V, +5V STBY,-15V, +15V STBY and +15V...
But not fixed yet..

So HELP HELP, I need these circuits daigrams again...

Worked R-1022 receiver with DC-28V operation:
Reassembled the PSU and suppllied at 28 DC voltages at PWR(ALIM.)
Stanby SW on at back-panel and Power SW ON at front-panel, All LED's on PSU was lighting ,
Receiver noise sounds/LCD dispalyed initial Freq, 12.3456Khz..
BUT, I can't fixed AC100-220V operation yet, but DC28V operation is good jobs..
Next thing to do, How to operate AC100-220V operations. It's so hard


I hope to getting these scircuits diagrams for AC operation..

Hi ! Great Hf receiver but there is nothing special compared to a Racal 3701 or Hagenuk Rx1001m or similar hf receivers.
Are your receiver for sale?

Thanks

Perfect !!!!!
Wrk is working.

Esito Positivo is good working.

I 'm not able to find the schematics of power supply modul sfortunately.

I think is better to power the radio with 28 volt mode than 110/220 volt.
The time is correct , you have replace the dump battery?

This is the tx of r 1022

Thanks for message.. Claudio san
It’s not for sale..Just fixing my friend's one..
So, you have very nice receivers, Racal,JRC and so on.
Enjoy!!!! With these nice receivers..
Have a good day from Japan.

Thanks, Emanuele san.

I could finally works with DC28V,,BUT I'd like to operate AC input.
and will hope to Mr.Koji san too.

I doesn't change the back up battery, It do Mr.Koji san chenged at May,2018..
(It is written in Japanese on some unit.. Pink labeled)

At AC opearation,
I wonder, AC input is Pin24 and Pin 13 at D-sub25 connector.(0016jpg)
but my verifications, pin24 is doesn't connect any circuits ,I guess.
and Pin12 and pin 13 connects AC input on circut (PCB)

Anyway, more checking/traceing the PSU circuits boards.
If you have another infomations about this PSU, Please Let's me know..

Thanks

Haru san, fantastic!
Thanks for sharing. I believe, you will manage to repair perfectly someday because you have lots of experiences.

Emanuele san, meraviglioso!
I envy you have a very nice and super rare transmitter matching with R-1022. Very cool!!
I think you must be the only person who has TX and RX of R1022 out there.

Btw, did you put LEDs at the corner of the display as LCD illumination for the Transmitter? As you know, originally EL backlit brightness is very dark. But I've never checked inside of the R1022 LCD module. It's not easy to replace EL panel?

Thanks, Koji JL1HID

Goodmorning Koji San!!!.

When my power modul is explose I have look for to replace this modul with other not original to make the +15 volt, -15 volt, + 5 volt and + 24 volt but this project is dead !!!!!!sfortunately I have't Free time.

I have no INFORMATIONS and circuits diagram of the black modul because isn't a Elmer 's project and it isn't in the manual of elmer of r1022.

In my tx display was broken the backlight (the inverter of 120 volt is ok) and I have put 2 led inside the modul of lcd .
