Had this beaut Rystl CB-4082 from Carl in Victoria come in for a once over, alignment, RR CYB1 VCO block install and a basic channel extension utilising CB/PA switch.
Into the points below …
* NO LSB: (Dirty mode switch contacts, ),
* MODS → FACTORY: ([Unlocked Clarifier: → Back to stock, ], ),
* MODS APPLIED: ([TX CLARIFIER / OFFSET: Fixed → Trimmer, ], [CB/PA SWITCH = Extra Channels, ], ),
* DeoxIT F5: (Potentiometers, OSC trimmer capacitors, ),
* DeoxIT D5: (Switches, Channel block, Mic PTT, ),
* SPRAY CLEANED: (Cases, Screws, Chassis, ),
* LUBRICATED: (All rotating controls, ),
* TIGHTENED: (All screws and nuts, ),
* REPLACED / UPDATED: ([ZZ-Z017 VCO Block → RR CYB1 V1.2, ], ),
* ALIGNMENT: (
- VCO VOLTAGE CH 1 / 26.965 MHz → CH 59 / 27.595 MHz = Aligned 3.99 V → 1.93 V,
- DOUBLER OUTPUT = Peaked Vp 149.6 mV,
- VCO OUTPUT = Peaked and balanced Vp 40.40 mV,
- LPF / DOWNMIX TO PLL = Checked @ Vp 4.480 V,
- CARRIER BLEED = Aligned min,
- BIAS DRV = Fixed & Checked @ 0.717 V,
- BIAS FIN = Aligned 20 mA / 0.635 V,
- SSB AGC = Aligned 2.03 V,
- PLL+LX REF+BFO OSC = Aligned @ AVG ~28.9 °C after 1 ½ hour warm up,
- TX COILS = Peaked & balanced,
- SSB MOD = Aligned @ 75%,
- ALC = ~12 W,
- AM RF PWR = ~4 W,
- AMC/AM MOD = ~90 %,
- 54 MHz / 2nd HARMONIC = Checked @ ~50.0 dB below fundamental,
- RX COILS = SINAD peaked,
- SSB RX = ~14.1 dB SINAD @ 0.222 uV 1 kHz offset,
- AM RX = ~10.2 dB SINAD @ 0.719 uV 1 kHz 30% MOD,
- S-METER S9 50 uV + AM RF PWR = Aligned,
- SQUELCH = Aligned, ).
* RADIO CHECK: (Saul 791).
Received excellent on air reports from local Saul 791 across all modes, and has nice clean sensitive receive. Ready to head back to the owner for on air time!

Hilarious, this radio still exists ... I have gotten one for Christmas in I believe 1979 😲

Yeh... not a common variant either.
