Thank you very much! I was thrilled to get it back after 35 years from relatives and in good condition. As you can see in my other KZbin videos, I’m still a radio hobbyist. I enjoy repairing, building, and modifying older and newer transistor radios as a hobby, focusing mainly on shortwave radios. Shortwave has been a long-time passion of mine, although I never obtained a HAM license. I’m simply a dedicated HAM listener.

This is a very sophisticated radio. I first had it 4 years ago. Repairing radios is my hobby; I buy, repair, and sell radios but do not take repair orders. Fixing older models is risky because replacement parts are no longer available. When I purchase radios, I select ones I believe I can repair. To clarify, I do not repair radios for customers-please understand this. I’m sorry for any inconvenience. This model is identical to SANYO 17H-815.You may can find service doccumentation for this SANYO model. That's it what I can help you.

I wish more people (countries) would still be interested in broadcasting (radio is magical, but less and less people see that) The hardest thing about being the listener only is that some day we will have nothing to listen to PS: I tried building the first one from the schematic and the onlything I was able to listen to on it was my noisy plasma television :( (I mean it does work, but I would like to listen to music not noise) I did get outside at night but its realy hard to find a lonly place where u can put 30m of wire above ground Will try again, I just hope that there will be something strong and close to listen to Because right now the closest thing (still standing) is 15kW station about 150km away, which is just to weak to drive the radio I do have Kossouth from Solt which is about 700km away, but I guess 2MW station is still to far away and to weak

There is always something to listen to on a good wideband receiver. I am using Yaesu VR-500 and ICOM IC-R20 wideband receivers. During the day, I can tune in to the air band, ambulance (911 emergency) calls, police communications from 30 miles away, HAM operators on higher bands (28 MHz), and the CB band. The FM band, AM broadcast band, and shortwave broadcasts from 9 MHz to 18 MHz are also good to listen to, even during the daytime-at least in my location.

Thanks for your recommendation about the direction finder antenna. After I removed it, the AM band sensitivity increased. I transfered the coil on the internal ferrite antenna, which is slightly longer than the one in the direction finder. That was the only reason for making the change.

The problem lies with the direction finder case itself. The design makes it impossible to re-tune the MW ( AM) band coil by moving or repositioning the coil on the ferrite rod. It’s very difficult to remove the case and access the coil to make adjustments, especially for re-alignment on the lower frequencies of the MW band.

¿Cómo agregaste el BFO? How did you add the BFO?
@imreolajossr6355 4 ай бұрын
It's not a simple one-two-three process; every setup is different, so there is no identical BFO installation process. I built a one-transistor BFO circuit and found the power voltage in the radio. There is a short, antenna-like wire connected to the BFO circuit, and this wire must be placed close to the radio circuit so that the BFO signal can produce the desired effect. The signal level must be adjusted by moving the wire, and once it's properly set, you need to fix the wire’s position with glue or another adhesive. It’s not an easy task. I always have 3-4 BFO circuits ready to assemble when needed.
