Hi Doug,

A case-swap was tried; chassis swapped from questionable case to known-good case. Didn't test the questionable cases with known-good chassis however. Good point.

Chances are this is an in-chassis problem. I hope it can be solved. The next thing I may try is swapping the VOCONs with known ...

Yep, LE is right on that. Electrolytics and MSFs have a bad marriage history. CLBs moreso than CXBs (famous no-name cap problem on CLB control board) but they're always a possibility.

Eric,

Make sure your primary supply voltage (feeding the station from its own power supply or another external source) is north of 12V or 12V at absolute minimum. The DC-to-DC converter can get unstable and not provide reliable 5V to the SSCB's digital core. Other funny things happen also ...

Hi Bob,

The MSFs should be recoverable. In the RSS, F2 section where Read/Write are, there should be a selection for "Read Station with Fatal Error" (F5). It may or may not be relevant to what you describe. Forcing a good codeplug in is another option. I believe even with a codeplug error, the ...

Good point. However, this is a known-good cable. It works on every other ASTRO Saber encountered. The RIB battery is also pretty fresh.

Howdy folks,

Picked up 4 ASTRO Saber Is... all IMBE. Two work great, one having had a minor problem of a loose spannernut causing intermittent power. The other two cannot be read.

Here're the specs known:

H04RDC9PW5AN
HOST/DSP unknown. (One might be HOST/DSP 7.some.thing, the other likely HOST 5 ...

Why bother getting another cable? Or even making a dongle? Put a toggle switch in the DB25 shell. Have one position for ASTRO and the second for Legacy Sabers / Systems Sabers. Pins 6 and Pin 8 are the only difference at the RIB (DB-25) end.

RIB-DB25 Pin 6 = ASTRO Saber Position
RIB-DB25 Pin 8 ...

There is a jumper on latter-revision SSCBs that is a PL indicate signal. It comes directly from an ASIC. It is labeled 'JU18' - I believe the center of this pin, properly buffered by an NPN transistor, will be just what the doctor ordered. The other method is use of the TTRC board's programmable pin ...

With all the (horror) stories I've heard about IFR/Aeroflex & their work with 1200 S's these days, I have no plans to send mine in. Other cal/repair houses might win my business someday if their prices and reputations are sweet enough. At this point, I can't afford their mistakes.. so far my unit ...

Have an MSF 5000 without a PA. This is a CXB station, rather than a CLB station. My manual shows jumper 'JU1' on the control board as the bypass jumper to prevent TX shutdown (test mode) regardless of the PA return signals. The manual is the Digital Capable Stations manual, not the original MSF ...

Well folks, still no success. I've tried re-seating the VOCON/RF board connection a few times with no change.

The radio still acts as though it's not even getting power. The light doesn't give the slightest blink when I click the knob on. The case is fine - checked that as one of the first things ...

Interesting..

I didn't do this at an ESD bench. I did the best with what I have here (haven't had trouble before). The case appears to be A-OK. I examined the flexcircuit carefully & it has good continuity. Power is getting to the rear of the radio. I highly doubt that I ESD'd anything on the board ...

Hi folks,

A bit puzzled, frustrated, etc. here....

Bought an AS 3 earlier this year. Everything working good, realigned it and got ASTRO TX working (alignment was way off), etc. Many months of good operation, no problems.

Then I decided to buy a DES-XL module seen on eBay. I'd prefer a dual ...

The alignment worked. Just confirmed it yesterday. The radio works perfectly now - analog and digital. Success is a beautiful thing indeed. All indications are that it's 'DNO' (dead-nuts on). Also a good indicator that my monitor is still in good cal. Two sighs of relief! Thanks guys.

Thanks for the feedback, fellas. I was hoping it would be something simpler than firmware/DSP issues. Being new to owning ASTRO equipment, I'm still in part of the intial learning curve.

While it's not a P25-capable monitor, I tried re-aligning the radio a few minutes ago with ASTRO Portable CPS ...

Folks,

I'm having an odd problem with my AS 3. Everything seems to work fine except transmission of IMBE signals. I can successfully decode IMBE signals such as LAPD, HT-to-HT or a couple of ham-band repeaters using Quantars here. However, transmission HT-to-HT or to the 2 local repeaters is a ...

Thanks Gary, I'll check that if my other attempted fix doesn't cure the problem I'm having. Thankfully I have a Logic Analyzer to look at the HSR & verify its proper operation. If anyone knows of any Pattern Generator, Clock Generator or Data Acquisition pods lying around for a Tektronix DAS9109 ...

Thanks guys, I changed my TX crossover freq. to 448.200 (an educated guess based on my experience) and so far, problem solved. 449.50 was the old (default) crossover freq. This had actually been my first thought of what to change, but I wanted to run it up the flagpole before trying. Never hurts to ...

The radio works perfectly with the 420 & 430 freqs that I have in it. Doubtful that it's a 450+ board. It does work in the repeater split scenario like you point out, willbartlett, so I'll give that a try. Thanks.

I'm experiencing some 'interesting' behavior with an ASTRO Saber III just purchased a week ago. It's an H04RDH9PW7AN (403-470) w/ the usual Nick 591008-4F1E00-9 flash. HOST version is R07.11.00 & DSP N08.02.06.

Anyhow, the problem I'm having is TXing on frequencies roughly the range 448.40-449 ...

Recently bought an MSF 5000 C74CXB, was stiffed on the SSCB. (Found missing upon arrival) Bought an SSCB on eBay from an 800Mc station, model TLN3090B.

After fitting it into the station, I powered the station up & the diagnostic display read 'd9A' - later lookup defines this as "SSCB HSR data In ...
