The TRC-394B is the CSF reference for an HF solid-state receveir used by the french army but also aboard french vessels. This model has been designed around 1978.
Here are its technical specifications (detailed specifications here):
- Receiving mode:
AM,USB,LSB,CW,TTY (ISB optional)
- Sensivity: [for (S+B)/B = 10dB]
- Frequency coverage:
12 fixed frequencies from
400Khz to 30Mhz
- Double conversion design:
1st FI: 67.5MHz,
2nd FI: 1.5Mhz.
250Hz CW (800Hz optional).
Tunable from 500 to 2000Hz.
This receiver uses CD4xxx CMOS technology ICs for the logical part, BF247B and 3N187 FET transistors for the HF stage and U6A775-7312, SL621, MC1350, TBA790 for the IF stage and TBA810S for the audio.
Most units are fitted with hardwired memory boards but last units are using a static RAM memory board to store the twelve fixed frequencies.
The TRC-394A is the same design but includes a VFO.
The TRC-394C is the latest design that offers far better performances and functionnalities.
