[Heath] RTO Status And My SB-102

[JOHN BIRDLEBOUGH]

More likely than LMO is the alignment is off SB-102 radios drift off because of component aging.  I replaced all my resistors and caps, with MOF and silver mica.  Now radio is rock solid, once it was realigned.  Worst problem to fix in SB-10X is the mechanical dial slipping problem.  And cracked dials.  Rest is repairable.  I normally do linears but a few SB-10X, Collins, Hammarlund transceivers end up on my bench.

Sounds fixable.

I thought there may be others on the list that woulod want to know this.

I received an email from RTO that they are cancelling all service requests on the waiting list. They will complete service on what they have received thus far but if you were waiting for the "go ahead and ship" as I was... well... the notification will not be coming.

Some years ago I bought a SB-102 from someone on this list. It has been on the shelf waiting for me to get around to restoring it since. I have been working on so much other old gear I just never seem to get around to the 102 so figured I'd give RTO a try. I am disappointed of course but understand that RTO has done a lot of good work for us over the years although I have not had an occasion to use their services until now. I am sure they will be missed.

With regards to my 102 I have it receiving on all bands. It seems sensitive enough but there is an issue that I expect is related to the LMO. From the low end of each band to the middle the receive is very stable. From the middle to the high end it is for lack of a better word "warbly". Any suggestions on what this might be other than the LMO?

Xmit also works with low drive. I imagine it also work with higher drive but every time I crank it up above 90 watts or so while in tune it blows the fuse in the Hp-23. I rebuilt the HP-23 with one of the boards from Harbach but the old circuit breaker was toast so I replaced that with a fuse holder. I don't recall if I had 3 or 5 amp fuses in there while tuning the 102 and blowing several fuses in the process. I figured this was something else that RTO would handle after fixing the "warbly"
receive.

Anyway any suggestions appreciated. I am not really up for messing with the internals of the LMO so if the concensus on the warbly receive is to tear into the LMO I may just offer it up here to someone more capable than I or as a parts unit etc...
