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)
