I've owned and restored literally dozens of the
HW-100/101 and SB-100/101/102 rigs over the years. To build on what AH6GI has correctly stated... The HW-100/101 have a traditional VFO, while the SB-100/101/102 have an LMO (linearized master oscillator) which is much more stable. The '102 has a solid-state LMO, while its predecessors have tube-type LMO's. The HW-100/101 VFO is tube-type. As AH6GI stated, the SB-line rigs have a better VFO frequency dial arrangement. The HW-101 and SB-102 use the same SSB filter, and it's very selective. Both can handle the optional 400 Hz CW filter, which is VERY selective. As a side note, you can use the Heath filters in a Kenwood TS-520/520S/520SE and vice-versa, since both use a 3395 KHz i-f! There are other minor circuit differences between the Heath rigs, and some physical differences too. The SB rigs have the VOX controls inside the rig, up on top, accessible through the hinged lid, while the HW-101 has them on the lower side of the cabinet, harder to get to. The SB-102 has more metering functions than the HW-101, although the meter itself uses the same movement. The SB-102 has capability to use an optional (somewhat scarce) remote VFO, and the HW-101 does not have this capability. The SB-102 is a better rig from a stability and user-friendliness standpoint. Performance-wise, they're a dead heat. The lion's share of the circuitry is virtually identical. If you have your choice for about the same cost, buy the SB-102. 73, Dean K5DH In article 0QMXZWh9EdSr-pn2-Ir1HbPlU7zrN@localhost, says...

The reason I'm asking is that I already have a decent HW-101, and I was just offered an SB-101 for a very reasonable price. If the SB-101 is a much better rig, I may buy the SB and sell the HW. Get the SB-101 unless you really love the HW-101. The SB-101 has the tube version of the LMO, 1 kHz frequency readout, compare to the, what, 5 kHz dial on the HW-101. The SB-101 is more stable too. A little discussed feature. The HW-100 has a broad slope SSB filter. I don't know if the HW-101 uses that or the 6 pole SB filter. If it has the HW-100's filter, which I believe is a 4 pole, then, for that reason alone, the SB-101 is a better choice. Either way, though. Both are good radios and plenty good enough. Why not get the SB-101, run your own comparison for 6 months or a year, then keep one and sell the other. de ah6gi/4 |
