lect different filtering for each receiver (VFO), thus allowing a slightly different form of the signal on each receiver. Experiencing this on stereo headsets will make a believer out of you.

Of great interest to SWLs (shortwave listeners) is the capability of AM diversity reception. This is accomplished by placing one receiver in USB and the other in LSB, then tuning the same AM signal.

Antenna diversity reception can only be accomplished with the BPF-1 option installed. It allows the use of a separate antenna for each receiver. This aids in reducing multipath distortion of received signals, particularly when using two different types of antennas (i.e, vertical/horizontal).

What I Liked

1 r The digital display is excellent and can be dimmed at the push of a button.

2t The frequency readout can be set up to display the 10 Hz digit (which I did).

3. Adjustable front feet, no pull down bail, to set the height and angle of the front panel.

4. The meter is large, well-lighted, and easily read,

5. Selectable attenuation is in S-unit steps (6 dB each),

6. The receiver's RF amp can be switched on/off,

7. Capability to monitor outgoing signal in SSB.

8. Two VFO knobs, one for each VFO.

9. Squelch operable in all modes,

10. Fast-tune button on the hand mike for up/down tuning,

11. Complete control over the internal keyer for weight and tone. You can even simulate a " bug" (semi-automatic key).

12. Selectable (by DIP switch} packet tone pairs and RTTY frequency shift.

What I DidnTt Like

1. The tuning knob, although using increments of 10 Hz, seems too fast for me. \ prefer a really slow turns/frequency ratio.

2. The noise blanker caused some distortion when strong signals were present on a close frequency.

3 I noticed a distinct dead spot in the receiver at 3,932.1 MHz (and a few other frequencies), 1 once noted a simitar problem on the Kenwood TS-14Q{atother frequencies). It creates no real problem, yet it is disconcerting when tuning across a band and hearing a momentary dead spot. I discussed this with Chip MargeJIi of Yaesu and he confirmed the existence of the unusual problem.

4. When entering a frequency via the keypad you must remember to insert a zero before the actual frequency for those below 10 MHz.

5. Having 99 memories is not to my personal liking. I cannot remember what is stored in each and prefer to use either the keypad or VFO for frequency control. I can see where they would be nice, however, for specialized uses such as RTTY or packet,

6. The cooling system only provides continuous duty at 50% power on RTTY, Full power output is limited to three minutes duration.

The fnstdes of the Rig

The FT-1000 is a new and different breed of transceiver, Yaesu, drawing upon its successes in the past with modular construction, has made this newest rig with a modular design, using many surface mount components. I see very little inside the transceiver that can be considered user-serviceable, but the modular design will probably make service easier for the technician and, therefore, less expensive for the owner.

The cooling system is novel, as it uses an internal squirrel cage fan instead of the usual computer-type traded fan. It is very quiet!

Optional Features

The FT-1000 has a number of options available, The BPF-1 Band Pass Filter, TCXO-1 High Stability Master Reference Oscillator, and optional IF Crystal Filters are the most popular,

The BPF-1 allows the subreceiver to be tuned to any frequency, using a separate antenna. It has 11 receiver bandpass filters and a switchable attenuation network.

The TCXO-1 provides improved frequency stability (see the specifications list).

A maximum of five crystal filters may be installed in the 455 kHz 3rd IFs, They cascade with the eight factory-installed filters and are

"if nothing else justifies the price of this transceiver, the quietness of the receiver does/'

available in 2.4 kHz, 2,0 kHz, 500 Hz, and 250 Hz for the main receiver and 600 Hz for the subreceiver.

Other options i nclude the CAT (RS232C level converter) and the DVS-2 Digital Voice System for recording received signals for instant replay or for canning outgoing messages, such asCQs.

Overall Marks

I have to rate the FT-1000 as a very fine piece of equipment and give the receiver extremely high marks for quiet operation Additionally, having the dual frequency receive capabilities, rather than only two VFOs, aids immensely in reception capabilities.

As mentioned earlier, when comparing its receiver to those found in current equipment of like monetary value from other manufacturers, the FT-1000 beats all.

Is it worth the list price of S3399 (FT-1000D with all options lists at $4399)? I have to, when comparing it to other rigs on the market, say yes. I hope some of the new technology used on the FT-1000 will soon be applied to the lower-priced rigs, thereby becoming available to many more hams.

Thanks to those fine folks at EEB, 323 Miil Street NE, Vienna VA 22180 for the loan of an FT-1000 for this review. VQ
