Hello, Time-Nutters-- In looking at the LPRO-101 unit I'm holding in my grubby little paw, I note that the base of the case has a thin layer of some sort of pale-green slippery material glued to it. Is this the heat-transfer tape/pad mentioned in the user manual that must be placed on the base before bolting to a heat-sink? I notice six threaded insert holes in the bottom for bolting to a heat sink-- The user's manual gives mounting screw clearance info for the bottom plate. However: I would like to place a small terminal strip on the top of the case with an RF connector and some easy/convenient connection lugs for power and monitoring, etc. Question--: how much clearance is there between the top of the case and internal components? It is not clear to me how to remove the top case section for a look inside to check on component clearance-- The top cover does not appear to be screwed in place, but I am reluctant to just try some experimental prying. Does the case slide off? There appear to be what look like tiny detent-dimples all around the sides of the upper case lid. Is this what retains the upper case in place? Does it lift off with very careful prying? Has anyone done this before? Thanks-- Mike Baker WA4HFR Gainesville, FL ------------------------

Note the position of the connector. This is really a filter plate with leads that also extend into the connector on the oscillator. Remove the two spacer nuts. Pull the filter plate out. Remove the cover. When you reassemble the cover, make sure that you install the filter plate correctly. I would like to know what the other connector is for and what the headers inside the oscillator are for. These are not mentioned in the manual available on the web. 73 Glenn WB4UIV At 01:21 PM 1/1/2009, you wrote: >Hello, Time-Nutters-- > >In looking at the LPRO-101 unit I'm holding in >my grubby little paw, I note that the base of >the case has a thin layer of some sort of >pale-green slippery material glued to it. > >Is this the heat-transfer tape/pad mentioned in >the user manual that must be placed on the base >before bolting to a heat-sink? > >I notice six threaded insert holes in the bottom >for bolting to a heat sink-- The user's manual >gives mounting screw clearance info for the bottom >plate.
