In addition there's one tuned IFT.
Now icf-swg it gets really weird: Image rejection: 83 dB (but spurious response.7 MHz only -40 dB) Okay, the manual receiver is apparently not that IM proof (not a big surprise, given the 7600G didn't fare so well there either but it never has that.
In case of the Sony AN-LP1 it turns on the antenna without need to use the antenna power switch.C114, C113/116, C115/117 Weak audio output, volume control needs to be manual turned way up Loss of one output channel Backlight (C221, the only 'lytic on the P board) Light dims very quickly (calculated time instruction constant is about 15 seconds, real usable time is somewhat less).I replaced the electrolytic capacitor on pin 23 of CX20111.Manual downloads at Sony - ICF-SW7600GR, ICF-SW7600G, ICF-SW7600, ICF-7600D Links Yahoo!External antenna jack, manual rec out jack (stereo, line level).7600group originally created with ICF-SW7600G in mind, abandoned and plagued by spam nowadays DRM modification for the SW7600GR A few measurements These numbers were originally from sony the 2002 wrth and partly posted on "7600group".Thanks for any insight (contact at bottom of page).7600group originally created with ICF-SW7600G in mind, abandoned and plagued by spam nowadays DRM modification for the SW7600GR, with notes on SW7600G differences The IF filters AM IF filter Murata ceramic filter SFR455I (which might be the same as a cfws455IT, the current P/N.Good selectivity, unlike the predecessor, it features a stand on the back, a rather sturdy one at that.General information, digital shortwave portable (dual conversion coverage: 150 kHz - 30 MHz plus sony FM (stereo with headphones) 1 kHz steps plus a frequency grid of 5 kHz on SW, 9/10 kHz on MW, 9 kHz on LW; sony 50 kHz steps. A wishlist for the successor (predating the ICF-SW7600GR Important things: More memories!
Weak bass reproduction even on headphones due to overly small coupling capacitors (see the 7600G tone mod ) - this repair contributes to the overly mid-centric AM audio.
C69 is situated near the CX20111.
Evidently, the purpose of this arrangement is to "inform" the accessory dragon antenna when the radio is turned.
Some kind of pre-selection (perhaps.5 MHz low-pass below some.2 MHz I pcs- really detest 49m images on 60m!, a 7 MHz high-pass above.5 MHz no 49 41m intermod please!, a 13 MHz high-pass above 14 MHz and.5 MHz high-pass filter.Commonly defective ones include C127 (in the DC/DC converter) and C69, but generally any of them (including those around the audio power amp) may be dead and even leaky.Powered through a 470 ohm resistence 100 uH coil.Only the paint on the tuning keys of my receiver is a bit origins worn off by now, and it seems I'm not alone with buell that problem.Other-sideband AGC pulling still is annoying but one cannot expect true SSB filters in this league.However, some antenna jack trickery allows for a considerable improvement (tested with a stereo mini-to-mini cable, but a stereo or possibly even mono.5mm / 1/8" plug should do Tune to a 160m frequency with some activity,.g.Apparently folding this is related to a slowly-locking PLL in these regions, which then cannot compensate for the VCO being influenced by signal strength in some way.I think this is the fix!Thankfully game the AN-LP1 antenna with its quite sharp 5 MHz range managed to free at manual least 60m from images and improve signal levels quite a bit.Regards to all, Ben McGee, VK2YEO, Sydney Australia.The small and slightly recessed slider switches on the side of the receiver aren't exactly suited for people with big hands.Hmm, as far as the limited function of my own SW7600 allowed I could not find any significant difference in image rejection.
