[Motorola] Surplus Syntor X's on eBay

[KBØNLY]

IF you can dig up that eBay users name, would be interested in trying to contact him.  A range 2 VCO is 150-174, so I'm not looking for anything too rare.  Unfortunately right now on ebay there isn't any VHF drawers for under $100.  There is one T73 drawer with an opening bid of $49.99, but I contacted the seller and he quoted me at $36.00 for shipping.  So that still puts me at roughly $86 if I won it with the bare minimum bid.

What did you do to replace the eproms on the personality board?  U502 should be easy enough, but how did you get a U501 with the right firmware for the radio?  

Thanks for the tip on the buzzing in the audio, I will remember that!  I usually go through and snug up everything on radio before powering it up, a lot of those screws tend to loosen up after years of bouncing around in the trunk of a service vehicle.

73,

Scott, KB0NLY

  Scott,

  It must be how you are searching eBay !  eBay discussions are off-topic for
  this list so I don't want to get into the subject too deeply or more than
  this one time, but I bought a VHF X9000 T73 drawer about two weeks ago from
  a company which had a large quantity of them, for the minimum bid of $ 25,
  and many of them went without bids !  This was just the drawer without the
  baseplate, and the eproms were missing on the personality board (as usual.)
  I could have had at least 5 or 6 more at that price.  He also had UHF X9000
  drawers at the same opening bid.  There was no range stated on the UHF
  drawers and I was afraid they were the 406-420 range FBI versions, so I
  didn't bid on those.  If you want to contact me off-list I can rummage up
  the seller's ID; I know he has a stack of unsold VHF T73 X9000 drawers
  because I just talked to him on the phone last Friday morning.

  I can't recall which frequency split VHF Range 2 is, and my manuals are at
  work.  If range 2 is 130-150, those seem to be very rare.  A 150-174 range
  works fine on 2 meters, but you have to retune the receiver front end
  slightly, and sometimes the VCO won't lock that far down in frequency
  without adding some pads to the stripline (see conversion reference on the
  BatLabs website.)  This isn't that much work, I have converted many Syntor
  X's to 2 meters and they work just fine.  On the X9000, I am not sure what
  the RSS does when you try to enter 2 meter frequencies; it depends upon
  which version you have, as I recall.

  Which reminds me...tip of the day for Syntor X and 9000 radios.  If you have
  a buzzing, high pitched sound superimposed on the audio when signals are
  being received, tighten the torx screws with the plastic insulators under
  their heads, in the vicinity of the front connector on the personality
  board. When they work loose, they apparently cause the bypass capacitor
  block on the data lines to lose ground contact.
