- Notes
-
Sony ICF-2001D: Double conversion portable multiband radio, coverage 150 - 30000 kHz, FM 76 - 108 MHz, additional AIR band 116 - 136 MHz AM; AM, SSB (USB, LSB, ECSS-Sync), digital frequency readout, frequency keypad entry, 32 memories, clock.
Internationally, different variants were sold:
-
Version 1 (standard / international): frequency coverage 150 - 29999 kHz, 76 - 108 MHz and Air Band 116 - 136 MHz; SSB reception, external antenna jack
-
Version 2 (Germany / Deutschland FTZ): frequency coverage 150 - 26100 kHz, 87.5 - 108 MHz, no Air Band; SSB reception, external antenna jack
-
Version 3 (Italy ?): frequency coverage 150 - 285 and 530 - 26100 kHz, 87.5 - 108 MHz, no Air Band; no SSB reception or external antenna connector
On pictures, you can recognize the sets without Air band coverage, as they have only two white - grey push buttons AM / FM below the clock display, and not three.
Radio part uses 3 x D cells (4.5V) but under them are 2 x AA cells for the Microprocessor/Clock/Memory (labelled "computer supply").
A rotary encoder tunes "fast or slow" or can be locked off. It's also used to increment and decrement the clock and multiple alarms. Each of the four alarms can have a duration (0, 15, 30, 60 minutes) and radio memory. The tape socket has a DC signal to initiate timer recordings.Matching power supply is Sony AC-140W (blue label, 4.5 V rated, different voltages)
Similar U.S. model is the Sony ICF-2010 with a slightly different power supply.

Hallo Radiofreunde
Habe heute mal meinen Sony ICF-2001D aus der Vitrine geholt dabei musste ich diesen Fehler am Display feststellen was ist das kann man das reparieren.
Grüsse und Frohe Weihnachten

According to the Service Manual, the RF bands can be set differently. However, depending on the model type, specific hardware limitations are also implemented at the cabinet/keypad and on the electronic circuits, and these impede some RF band choices.
Location of the Diode Bridges on the KeyBoard PCB Assembly:
Jose Mesquita, 13.Sep.22
The original Service Manual (1985, 85C02129-1 9-951-647-11) lists the 2SK152-1 at several positions, namely Q302 LW/MW RF AMP and Q303 AM RF AMP.
However I found several versions of the Small PCB assembly (RF Input and I/O sockets, at least these ones exist:
- 1-614-277-12 and 1-614-277-13 (label at the copper trace side) - Older boards, older style "SMD" components.
- 1-614-277-15 (label at the oposite side of copper trace) - Later board, redesigned PCB copper traces, uses common SMD components at trace side.
At least on 1-614-277-15 PCB assemblies, both Q302 and Q303 uses the 2SK152-2 installed from factory.
The 2SK152-1 and 2SK152-2 have different specifications, namely IDSS operating current. Therefore the reference voltage points at Dreno and Source of these 2SK152-1 JFETs listed in the Service Manual may not apply entirely to the 2SK152-2. I observed large variations, especially on the Q302, despite the radio being operating very well. That said, those reference voltages are still useful as a starting point for troubleshooting.

Hallo, liebes Forum!
Bei meinem ICF-2001D besteht das Problem, dass der Schieberegler für die Lautstärke mittlerweile stark kracht. Selbiges Problem habe ich auch beim kleinen Bruder ICF-7600D. Gibt es eine Möglichkeit, diesen nachhaltig zu restaurieren (also nicht Kontaktspray 'reinknallen)? Falls nicht: Kann man diesen Regler heute noch kaufen?
Über eine Info würde ich mich freuen!
Viele Grüße,
Torsten, DL8KFO
