This good old Sommerkamp FT-277 EE HF rig was donated to me by a super nice amateur called OZ1CBW
It is also called Yaesu FT-101
Really good gedine hardware weight 15.2kg
TX Power 150W SSB and 100W CW

The band switch goes like this:
A = 80m is 3.5 to 4.0 Mhz
B = 40m is 7.0 to 7.5 Mhz
C = 20m is 14.0 to 14.5 Mhz
D = 15m is 21.0 to 21.5 Mhz
E = 11m does not work
F = 10A is 28.0 to 28.5 Mhz
G = 10B is 28.5 to 29.0 Mhz
H = 10C is 29.0 to 29.5 Mhz
I = 10D is 29.5 to 30.0 Mhz
J = JJYWWV is 10.0 to 10.5 Mhz RX Only
K = 160m is 1.5 to 2.0 Mhz RX Only

I have re-assigned the Mic pins so that this rig has the same pinouts like on my other rigs
Before: 1=GND 2=Mic 3=PTT
Now: 2=GND 1=Mic 4=PTT

S-Meter readout versus input signal:

S      ATT OFF      ATT ON 
1      -96 dBm      -76 dBm
2      -92 dBm      -72 dBm
3      -86 dBm      -67 dBm
4      -80 dBm      -60 dBm
5      -77 dBm      -57 dBm
6      -74 dBm      -54 dBm
7      -71 dBm      -51 dBm
8      -68 dBm      -48 dBm
9      -65 dBm      -38 dBm
9+10   -58 dBm      -29 dBm
9+20   -50 dBm      -19 dBm
9+30   -39 dBm      -12 dBm
9+40   -31 dBm      -?? dBm
9+50   -26 dBm      -?? dBm
9+60   -22 dBm      -?? dBm
You see the S-meter is really good, also this rig can hear a tone at -130dBm, Really good..
