When I'm bored, I have been in the habit of doing bandscans, which is incredibly boring, and by comparison, the previous state of boredom I was in previously just doesn't seem that all that boring after all. 

Hope you don't mind if I share them here.  It makes it a lot easier to have target ideas handy on nights when there are good openings.

Came in from combing a BA turd out of my dog's coat to hear final song and ID block.  Sounded like "WFMT" on a couple of plays of the tape.  Good sig and I got good audio here.

Ran across this...

I guess when I hear the term OTH Radar, I immediately think in terms of military use.  This piece of corpo-propaganda suggests civilian and scientific uses (e.g. tracking iceberg movement).  That certainly doesn't bode well for the future. 

Perhaps they can use it in the short term to track UARS...I've got Pakistan in the pool at work.

Chris;

A very timely post for me.  My R7 is plagued by 3 annoyances, 2 attributable to old age, and one by design.  I was looking at this a short time ago and decided that the DDS-60 accompanied by an Arduino SBC should be able to solve all three problems.  First, the R7 PTO gearing just reaches the far end of the bathtub curve at some point.  The plastic gears become worn, out of round, and prone to lockup.  Using a DDS to implement a digital VFO would be a nice replacement.  Most likely will just need a simple BPF to get to the spectral purity of a permeability tuned oscillator.  Secondly, the band Up/Down buttons at some point just get tired, and are prone to contact bounce.  No amount of contact cleaner seems to do the trick for very long.  Punch Up, and it can be a guess as to what frequency band you end up on.  Thirdly, the RIT control is difficult to use by design; +/- 2.5kHz in a single turn pot makes it very difficult to use in practice.

An Arduino has a lot of flexibility for $30.  14 IO lines to handle DDS loading, frequency increment/decrement buttons, etc.  One of the on board 10-bit ADCs could be easily used to implement the RIT function and possibly the Passband Tuning function (do I see a joystick here?).  It has EEPROM which can be accessed by the code (written in C) to handle last tuned frequency, memories, etc.  It does have a USB port which is used to download code from the compiler, but which can also be accessed programatically for control by a host program.

All in all, one should be able to put together a great PTO replacement for a lot cheaper than an RV75.

Thanks for the post!
