I have a 1254 and really like it. It is sensitive and stable. The
steel case makes it rugged and professional looking. It has a balanced
JFET mixer in the front end and an AGC-driven automatic attenuator to
keep it from being overloaded on strong signals.
It is a no-frills design, with only 5 kHz tuning steps on AM and 2.5 kHz
steps on SSB/CW. It needs a coax-fed antenna. Using a single wire or
whip antenna will cause harmonics of the digital display multiplexer to
get into the front end and cause birdies. There is a mod to add
shielding to the back of the display board.
It would lend itself well to mods and experiments, like adding an LED
bargraph S-meter, mute circuit, audio filter, or a different crystal
filter. The stock 4 kHz filter is fine, just a little narrow for Hi-Fi
broadcast listening and a little wide for SSB and CW.
I use mine primarily as a bedside radio. Its great for a little
late-night CW copying or monitoring airline traffic on SSB. When I wake
up, I can catch the news on Radio Australia.
I use it with a low (NVIS) 80 meter dipole or a 40 meter loop. For
battery operation, the specs say it draws 250 mA. This could be reduced
by adding a switch to shut off the LED display.
Its no contest radio, but I wish I had a receiver this good when I was a
Novice! Yes, you could buy something like a Sony 7600GR portable to
meet your needs, but you'd miss the fun of building it. If you want it
for emergency backup, you could build a QRP CW transmitter to go with it.
