[Heath] Heath choice for IF

[Bill Cromwell]

Hi,

The Apache had a phasing type SSB adapter external to the transmitter. I 
didn't have a Mohawk. That was the HB-10 and could be fitted to a 
DX-100. The DX-100B was made to accommodate an SSB adapter and the 
DX-100 could be modified for it.

I don't believe the Mohawk had xtal filters but L-C filters in a low 
final IF. I never had a Mohawk get within striking range during the ~20 
years I had the Apache. Maybe the SB-100 series radios had those 
filters. I have the info somewhere about the Mohawk and some of the 
others but it is not 'near-line' at the moment. I have to physically 
mount a hard drive to access it. *Deep storage*.

I do still have the DX-100 and the DX-60/HR-10 but I let the HB-10 go 
with the Apache. The HR-10 has a simpler xtal filter (2-pole) but not 
the 3.395 MHz unit. the Kenwood Twins (I have a set) uses 3.395 MHz xtal 
filters and possibly some other radios do. I have a set of SSB and CW 
xtal filters from the Heathkit series for a project here.

73,
