Sherwood Engineering HF Test Results

ModelHilberling PT8000ASerial # 12080134Tests:Sept&Oct2012+ May 2013

Note: Hardware updates were installed in October from Rev 1.00 to Rev 2.00


Note 2: A new filter board was installed in May 2013 for hardware Rev 3.00.


This added a 250-Hz 16-pole CW filter for both Main and Sub receivers.


At this point this update will be standard in US transceivers, and an option in Europe.


All measurements made on 20 meters unless otherwise noted.

Note:


The S-meter linearity is very accurate, as are the S-meters in the Flex products and the

Perseus. The S meter reading is not affected by preamp, attenuator or hybrid splitter

settings.


If the splitter is not desired for the Sub receiver, be sure to switch the Sub receiver to

antenna #2 to take the splitter out of the circuit if maximum sensitivity is desired on the

higher HF bands. Due to band noise on 30 meters and below, having the splitter in the

circuit would cause no practical degradation of reception of weak signals.


The LCD display is outstanding, with excellent brightness at the default backlight level.

The display is angled internally, so it is not mandatory to use the tilt-bail for easy viewing

of the screen.


Markings on the front panel are very legible in white on the dark charcoal background.

No need to use a flashlight to read the panel, unlike some other brands.


With very weak signals, broadband noise outside the crystal-filter passband is

dramatically reduced by enabling the audio DSP filtering. While this only has a minor

effect on measured noise floor (1 to 1.5 dB), audibly the improvement is significant.


With the addition of the 16-pole CW filter, the audio-derived AGC option will no longer

be available or needed. This feature caused problems with S9 or stronger signals,

particularly if the preamp was enabled. (This change will occur in firmware update.)
