 VT-F430A HITACHI Service Manual by Thomas Hirz;
I needed the manual immediately and I got it immediately. I couldn't find this manual anywhere else on the net. The site was easy to traverse, and the price was very reasonable. I'll definitely be back for any future needs.
 AD-WX200 AIWA Service Manual by Angelo Gallina;
I received a good service manual, with good resolution. Improve the instructions for the purchase because they are not well understood. For the rest, so good. Thanks Angel.
 2077 GRUNDIG Service Manual by Herman Wiegman;
Very good documentation for the Grundig 2077 model (as well as similar 800/900/1000 series radios). The first two pages are a summary of reception specifications and output capability. The third page is the tuner dial indicator and dial cord routing diagram. the final ~5 pages are the schematics for the various models (including 2077). The scan quality of the schematics are good, adn can be easily read if zoomed in. The documents are in German, not English as stated. It would have been nice to have the tuning sequence and settings, and some trouble shooting materials... or component and wiring map.

3) Recording a message
The signal sent from the microphone is output from pin 11 to pin 10 of the analog switch (IC219), where it enters into the CODEC (IC217). The signal sent from the CODEC enters pin 13 of the DAC (IC212), and is then sent from pin 14 to the optional unit (VGS-1) to be recorded.

2) Playback
The output signal (VOI) sent from the optional unit (VGS-1) passes from pin 1 to pin 2 of the DAC. The signal passes from pin 8 to pin 9 of the analog switch (IC219), and is then mixed with the input signal of the AF amplifier (IC734). The DAC (IC212) controls the volume.

â  Constant received audio recording function 1) Recording
A part of the received audio signal is sent from the CODEC (IC217) to pin 13 of the DAC (IC212), and is then sent from pin 14 of the DAC to the optional unit (VGS-1) to be recorded. The recording level is automatically compensated to become constant and you cannot randomly change the level.

â  Other functions 1) Playing a message (monitor)
The output signal (VOI) sent from the optional unit (VGS-1) passes from pin 1 to pin 2 of the DAC. The signal passes from pin 8 to pin 9 of the analog switch (IC219), and is then mixed with the input signal of the AF amplifier (IC734). The DAC (IC212) controls the volume.

Modulation Circuit
The modulation signal processed at the DSP is sent to the modulation circuit. The circuit receiving the modulation signal is different between FM mode and SSB/ AM/ FSK mode. ceiver generates the FSK signal by changing the single tone (AF) generated at the DSP. The balanced modulator performs the same operation as SSB mode. ⢠CW/FM mode The necessary carrier wave is obtained by making the balanced modulator lose balance.
Q625 (1/2) DC for AM/FSK TX-RX unit (A/2) DSB OUT 10.695MHz

1) SSB/ AM/ FSK mode
The modulation signal sent from the DAC (IC212) enters the balanced modulator (IC621) after inverting the phase at Q625. The 10.695MHz transmission signal sent from the balanced modulator is amplified at Q621 and is then sent to the next stage. ⢠AM mode The DC voltage is applied to the pin 1 of the balanced modulator via D624. With the DC voltage, the AM carrier is generated since the balanced modulator becomes unbalanced. ⢠FSK mode In conventional FSK mode, the frequency of the carrier was changed with the external keying signal.
