- I had one for a while (from ACE) and sent it back and got a
- refund.
-
- It came with a dead AC adaptor. They had to send me another.
-
- To tilt the front up you put a little wire doohicky on the
- front rubber feet. It kept falling off.
-
- The display was poorly back-lit (actually side lit) and hard
- to read: you had to be just about 90 degrees to the surface to
- see it.
-
- Some of the buttons had painted legends, others had what
- looked like decals which might wear off.
-
- I didn't try the computer interface. It was poorly documented
- (some information was missing which ACE had to send separately).
- It uses a VERY weird format, with a mixture of ASCII and binary.
- You have to encode the frequency, mode, step width, etc, into a
- binary format to program the unit. Possible, but not easy.
-
- Performance on lower frequencies was very poor. It could pick
- up the strongest AM and Short Wave stations, but not much else.
- It picked up a LOT of noise from the internal microprocessor. You
- could hear the background buzz change frequency each time you
- pressed one of the keyboard buttons. An outside antenna didn't
- help any.
-
- Performance on higher frequencies was not much better. It
- still picked up a lot of internal interference, and had very poor
- image rejection. A lot of the 800 MHz band could not be received
- because I got UHF TV station images.
-
- I compared it with two Bearcat scanners (both hand-helds,
- different models) in the middle of the parking lot where I work.
- Both Bearcats clearly picked up signals I couldn't even find on
- the AOR, even when I entered the frequency directly.
-
- I have since bought an RS-2006 which has none of the above
- problems.

- It might actually be possible with a Heath SB-10 sideband adapter. I
- seriously considered this option once. The SB-10 was designed to
- work with the Heath Apache transmitter. It was a phasing type sideband
- generator which was designed to be inserted between the driver and final
- amplifier stage. It would require that you make some rather extensive
- modifications though. I think I would recommend against it unless you
- just want to try it for experimental reasons.
-
- By the way the transmit audio quality from an SB-10 was amazing. Yes
- I did end up using one with an Apache for many years.

- Is one of the holes D shaped? Sounds like it is an Amp series connector.
- They look similar to the Molex connectors, but rather than having the >

- To: ham-equip@ucsd.edu
-
- I am also interested in the Timewave DSP-9. I am especially interested
- in how much real audio gets through the thing.....does it take the
- audio and chop it up much when it gets to the speaker? I really like
- my fidelity (such as it is from my 2.1 kHz filters), and would hate
- to make it worse, though the auto notching is a very nice feature.
-
- Would love to hear from owners!
