Hello all..in the middle of doin' a re-alignment on this one..ran into puzzling instructions on page 10 of manual on the bottom..on band 4 the 12-31mhz area..it says using a sig generator adjust L-1 then L-7 while tweaking the ant trim cap..problem is that this L-7 coil does not have or even ever had a slug..this coil is listed in the parts as L-7/8..an antenna coil for band 4..coils L-6 or L-5 have none either and they are antenna coils for other bands..I really think they meant to say L-9 for this adjustment but ya know what?..I'll wait on another opinion to agree or not here..it's most likely a "typo"
Thank you thank you for any input..I can wait..no hurry here..too damn hot!! 73 de DAVE
As far as I know, Hallicrafters never issued a service bulletin for the SX-130 but at reviewing both the S-129 and SX-130 schematics and tracing the bandswitch contact connections to the specific LC components, here's what I found:
In the alignment table:
(SHOULD BE) Step 8 - Signal Generator Frequency 14 MC. Band Selector-4 Tuning - 14 MC - Adjust L1 (Osc. coil), Adjust L9 (mix. coil), C13 (ANT TRIM)
The original designation L7 (mix. coil) is incorrect.
The parts list is correct.
Further, while checking the S-129 documentation, there is also an error in their alignment table (different then the above error) and there is a designation error in Figure 11 of the same S-129 document.
Note that the S-129 is the same as the SX-130 less the "S" meter and crystal filter.
