Radio ideas part1

The proposal below is an enhancement of PL660 with most important specifications of various DSP models from Degen and Tecsun and a bit of Lowe HF150 . This idea is surely a hypothetical model that could be feasible in case Silicon labs could enhance their SI 7434IC chip with better SSB

[(<360 ) spec derived from 360]

• • Very high sensitivity , if possible with high dynamic range as Lowe HF150

  • Very low self noise (<380)

  • Freqs : LW , 520-17xx for MW , 2-23 for SW , 6x-110+ MHz for Fm (full Fm band plus 2-3 mHz for out-banders ) and possibly working AIR band (PL600 didn't work )

  • Modes : AM LSB USB {ISB/DSB} FM DRM???

  • Filters : several for AM /SSB including 2.7 and 6 (proposed 1 /2/3/4/6/9/12?/15? for AM and half for SSB ) kHz with full audio fidelity (<1103) ,

  • Filters : two for FM auto narrow and auto medium (as all DSP models)

  • FM mono and stereo

  • FM step 5 or 10 kHz (<360, x00))

  • AM synchro (<660)

  • Smooth soft mute as in PL380 or DE17 /XH D808

  • AM step to .25 kHz SSB step low to 0.01 Hz (closer to HF150 or R75)

  • Built in 4 or 8 GB memory (<1126) a/o include SD card slot for recording

  • Ability to record from radio , using true MP3 recording on 24/40 (AM)and 96/128kbps (FM) (<Creative Zen /Q3)

  • [MP3 WMA and pres. OGG support (<1126) ]*

  • [True shuffle operation (as most mp3 players )] *

  • Analog volume control (<360)

  • PL 360/380 audio fidelity for earphones

  • Field meter as 360,380,880 (dbu S and db S/N ) if possible with true strength meter

  • Numerical keypad

  • [antenna tuner or external preselector ] (<600)

  • External grounded antenna input for SW/FM , and possibly for MW

  • Standard AA battery compartment with >250 mA charger USB type

* in case radio includes mp3 player

Ideas addon :

• • noise blanker

  • a n l

Ideas subpart 1

• • Includes DRM

  • Ability to decode RDS

Ideas subpart 2: (lite version dimensions as 1126/1127 )

• • No SSB

  • Very high sensitivity , very low noise

  • Steps of .5 kHz for AM , 10 kHz for FM

  • Higher audio outputs than 1126 with more steps

  • Automatic volume gain in soft mute signals (as with DE17)
