Yes thank you i got the file i was after. There was a slight problem in my communication but it all worked out well.
A job well done.

Great manual...really saved me. The only problem is that I thought I would be able to download it directly when I paid for it but never received the download instructions until the next morning. The board trace pages were somewhat light also: really need to turn up the contrast on the printer before printing them. The schematic page was great; very clear! Well worth the money.

I've been in the electronic business for a long time. I used to buy Sam's Photofact for my needs which intailed having to go to the store and paying about $20 for a package of 3 different units so I was forced to buy more than I needed just to get one.
Owner manual is just at your keyboard and the information is almost instantansouly and the cost is very reasonable. Easy to print out if needed or simply read off of the screen. The larger the screen the better for obvious reasons.

Very good manual, at a very good price. Received in a timely manner

Only thу cover has poor quality, internal material has excellent quality - exactly what I needed
Thanks!

FM Abgleich
GB
FM Alignment
Bitte achten Sie darauf, da� die Stationstasten vor dem Abgleich mit bestimmten Frequenzen belegt werden müssen (siehe Seite 5).
Please observe that the station preset push-buttons have to be programmed to specified frequencies before the parameter programming (see page 5).
FM Phasenschieber - Abgleich
Künstliche Antenne (8 627 105 356) verwenden. Betriebsart ................................ FM Stationstaste ............................ 1 (97,2 MHz) Me�punkt ................................. MP 153 (X12/7) Abgleichelement ...................... Z 152 Spezifikation ............................. H>L Sprung Me�instrument ......................... Oszilloskop Signalquelle ............................. Me�sender f = 97,2 MHz, fmod = 1 kHz Hub = 22,5 kHz Signaleingang .......................... E' = 40 dBµV (+Bedämpfung!) 1. Klemmen Sie das Oszilloskop an MP 153 und Masse an. Schalten Sie den Oszilloskopeingang auf DC. 2. Stellen Sie den Me�sender auf 97,2 MHz, mit 22,5 kHz Hub und 1 kHz Modulation ein. 3. Speisen Sie das HF-Signal E' = 40 dBµV in die Antennenbuchse ein (Dämpfung der künstlichen Antenne beachten). 4. Drücken Sie die Stationstaste 1 (97,2 MHz). 5. Verstimmen Sie den Me�sender mit 1 kHz-Schritten um die halbe SL-Stop-Fensterbreite, d.h. auf 97,170 oder 97,230 MHz (siehe Skizze). Zwischen 29 kHz und 31 kHz von der Fenstermitte (97,200 MHz) sollte der oszillierende H>L Sprung an MP 153 erfolgen. Erfolgt der H>L Sprung nicht, geben Sie die halbe SL-StopFensterbreite von 30 kHz am Me�sender vor (97,170 oder 97,230 MHz), und stellen Sie den H>L Sprung mit Z 152 an MP 153 ein. 6. �berprüfen Sie abschlie�end die Fenstersymmetrie und korrigieren Sie die Einstellung von Z 152 ggf. erneut.
FM phase-shifter alignment
Use the dummy antenna (8 627 105 356). Operating mode ....................... FM Preset button ............................ 1 (97.2 MHz) Measuring point ....................... MP 153 (X12/7) Alignment element ................... Z 152 Specification ............................. H>L change Measuring instrument .............. oscilloscope Signal source ........................... signal generator f = 97.2 MHz, fmod = 1 kHz deviation = 22.5 kHz Signal input .............................. E' = 40 dBµV (+attenuation!) 1. Connect the oscilloscope to MP 153 and ground. Set the oscilloscope input to dc. 2. Adjust the signal generator to 97.2 MHz, 22.5 kHz deviation with the modulation of 1 kHz. 3. Feed the RF signal E' = 40 dBµV into the antenna input (observe the attenuation of the dummy antenna). 4. Press preset push-button 1 (97.2 MHz). 5. Detune the signal generator with steps of 1 kHz by half the width of the search tuning stop window, i.e. to 97.230 or 97.170 MHz (see sketch). The oscillating H>L level change at MP 153 should appear at about 29 to 31 kHz off the channel centre (97.200 MHz). If this is found to be different, tune to an offset of 30 kHz (97.170 or 97.230 MHz) and use Z 152 to adjust the H>L change at MP 153. 6. Finally check both slopes with regard of the window centre and make a correction if necessary.
Beispiel:
funterer H>L Sprung + foberer H>L Sprung 2 = fFenstermitte
Example:
funterer H>L level + foberer H>L level = fwindow centre 2
97,170
+ 2
97,230 = 97,200
97,170
+ 2
97,230 = 97,200
Die Abweichung von der Fenstermitte (97,200 MHz) darf bis zu ± 2 kHz betragen.
The permissible unbalance of the centre is 97.200 MHz ± 2 kHz.

� Im Anschlu� an diesen Abgleich müssen die DX/LO Programmierungen für FM und die RDS Grundempfindlichkeit neu programmiert werden (siehe Seite 11 + 12). - 16 �
97,231 MHz
At the end of this alignment DX/LO programming for FM and RDS - basic sensitivity must be redone. (see page 11 + 12).
