Hi: Thank you for all the information on the SBE-34.
The one piece of information i need though are the
power connection pins. If i knew what pins to connect
an AC cord or 12Volt supply to, i could check it out. I
once owned an SBE33 and enjoyed it.

I am so glad to hear Kieko is better. Strength to you in your time of crisis.
It is refreshing to see analog communications still alive and well.
Please tell us more about America and why you returned to Japan.

Re. SB-34. Very enjoyable story. I have operated one "sometimes" over many years. Made many miles mobile with it years ago. Had many of the same symptoms you described. Good work and thanks.

The BFO, Sensitiviity and Bandswictches in my ICF5900W have become intermittent. I have tried spray contact cleaner but the switches seem to be sealed and the cleaner unable to penetrate. Wondering if anyone else has experienced this problem and found a solution short of replacement?

Thank you

Thank you very much for this site and images. It is most helpful to me in my restoration of the Hallicrafters S-20R receiver. I have been searching for a site like this and finally found it. The images and diagrams are high quality and extremely useful for my project. Thanks again abd I am indebted to you for the help this site has provided for me.

Does anyone have a manual for a Gakken "My Kit 150" electronic project kit? I think my kit was probably made in the 1970's or ealier. Would appreciate any help. Thanks.

I will be restoring a SBE-36 shortly. It would be great to see your restoration notes in English. Have you though about a translation?

Thank You !

I have a HQ-170a and at one time there was available a noise blanker for this and the HQ-180a Hammarlund recievers. Does any one know anything about this?

I just wanted to say how much I enjoy your web site. As a radio restorer myself, I can't tell you enough how I have enjoyed your step by step thought process and conclusions and how well written your pages are. They are a great tool to radio hobby people and I will continue to follow along on your radio journies.

Hello Lew:

Regarding the HQ-170 - what I observed in my unit is a noticeable frequency drift (chirp) associated with the incoming signal strength. I digged up that the local oscillator frequency within the 3rd frequency converter varies as the AGC voltage changes. I tentatively disconnected the AGC voltage from the 3rd converter, resulted in a chirp-free crisp code reception. I don't know if mine had a hidden problem which caused this, or this was an original characteristic of HQ-170A.
Slow, but continuous frequency drift is also annoying. I haven't studied what is the primary reason of this or haven't tried to reduce it. If this is caused by a aged component such as capacitor, then finding a replacement with compensable temperature characteristic will be quite time consuming although would be rewarding. For now, I keep this receiver for my future project (maybe after retirement...?)
