[R-390] RF Deck redux

[Flowertime01 at wmconnect.com]

Now that I have my RF deck back together and apparently everything is in
time, I have a sanity-check question...the two lowest-range slug racks
appear to only be affected by the kilocycle change control, whereas all the
others turn when you rock the kilocycle knob AND index when you rock the
megacycle change knob.

Brian,

True statements.

Roger.

P.S.

Remember in the low two octaves (.500-.999, 1-1.999) the range is under or 
equal to 1MHz. The Megahertz knob is a step bigger than the range of these 
two octaves.

In the upper octaves (2-3.999, 4-7.999, 8-15.999 16-31.999) You must also 
add some small change across 1Mhz of VFO range. so you get some small cam 
motion with VFO range.

On the 1-1.999 The cam is one to one with the VFO.

On the.500-.999 The cam is also one to one with the VFO and rolls over 
again from .000-.499.

As the whole set is tied to gather, and the deck has no idea what Mhz you 
are on, you see the bottom two octaves go through the full range of motion 
every time you run the VFO from end to end no mater which Megahertz you are 
using.

The upper octaves also make the required range of motion with the VFO. But 
as this is a small adjustment compared to the 16 Mhz of the top octave you 
do not even notice the change in the slug rack as you run the VFO from end to 
end. But you do see the index steps of the Megahertz changes and the small 
rocking motion of the Kilohertz changes.</HTML>
