I have a new s-9-50 with the "new" board and was wondering if they can be made to slide more on the course? I'm unable to get to in between ch's such as 27.380. The Course only slides about 30 in each way. Is this only with new boards or is there a mod? Other than that this is a "very hot" radio with a good rx. i was amazed at the swing this thing has. Does a solid 50w pep. Very nice radio. Also feels/has a lot better quality than was expecting. If I could lock the fine and add more course slide this would be a A+ radio.

If the course slides 30 kcs then you should easily be able to get to any freq. ending with a zero.Example clarifier centered on 27.385 you should be able to get to 27.370 one way and 27.390 the other.I have a SS158EDX which with the course I can easily drop down to the zero's such as 380 or up to 390.Maybe the freq readout doesn't change when you shift the clarifier such as the 158 does but as you said with a 30 kc shift the zero's should be no problem at all. Interesting note this is my 451th post on copper which = my CEF # 451 lol

You need to go 5khz in either direction to get "in between channels". Should be no problem to do with the s-9. I get 7khz with my S-9.
I would send the radio back for a repair before I tried a mod.

Found the reason for the limited "slide". It was only a issue on newer board s9's.

No problem for 28.380. Would be kind of neat to go near 40mhz but my antenna might not agree with it.

darn .....
just realized I said 38.380..
I meant ch 38 then sliding in between 38 and 37 or 27.380.

Oh boy im getting old...

Anyway it seems this was only for the "newest" of S-9's that came out in the last month or so with the new board..

My magnum s9 only has 3kc shift up or down. Can anybody tell how to get 5kc or more? When you do dx from over seas you need it.

ENGINEERING CHANGE NOTICE


PROBLEM DESCRIPTION (be specific) Date: July 16, 2008
This ECN describes the changes required and re-tuning to ECN No. F16078
increase the clarifier range to +/-5 kHz. Requested by: EDC Inc.
This modification applies to S9 radios built on the 0619 board Engr Approval: EDC Inc.
only. RF Ltd Approval
Service Approval
Mfg Approval
Field Retrofit? Yes
MOD LEVEL CHANGE?

APPLICABILITY S3-50 S6-50 S9-50 S3-80 S6-80 S9-80 OTHER
List Serial Numbers Affected (if known)
0619 R4 boards only N N Y N N Y All Nitro S9’s



SOLUTION
Remove covers and verify the silkscreen on the component side of board reads PCBX-0619R4.
If it is correct change the following components:
R911 was: 10k is: 20k
R137 was: 1k is: 150 Ohms
C330 was: 6pF is: Removed.

Remove shield on solder side of PCB to access C330 and replace after removing C330. Re-tune the PLL
per the following procedure. Set Frequency of radio to channel D20 (27.205MHz). Adjust coarse and
fine clarifier knobs to center detents. Remove screw holding MCU module to side of radio and move MCU
module out of the way to access L19, L20, and L21. Set radio to AM mode and adjust L19 until frequency
counter reads 27.2050 MHz. Set radio to USB mode and adjust L20 until frequency counter reads 27.2050
MHz. Repeat in LSB mode and adjust L21 for 27.2050 MHz. While in LSB mode adjust coarse clarifier
adjustment to ensure it tunes +/- 5 kHz or more. Replace MCU module and covers and bench test radio
for normal TX and RX operation.

Modification complete.

hello,

I have a Magnum S9-175 as a card: PCBX 0619R6.
This card is very different with 0619R4.
Indeed, the coils L19 & L21 are not present on the card.
Points to connect an external frequency counter are not shown, as for the other versions of S9.
I looked everywhere on the Internet, but on any site talking about this card PCBX 0619R6.
Magnum S9-175 comes with a diagram of this card, which is based on an S-980.

My questions are simple:
how to set the s9-175 at the clarity and frequency shift?
how it's done all the other settings on the S9-175?

Hoping for a response, thank you all.
Marc
