Correction, 40ma would be enough.

willbartlett

Might not be a problem. I'm just trying to power a small microcontroler board off it, so even 100ma might cut it.

Hi All. I have an application where it could be helpful/less complex to power up a peripheral from the B+ line on the Jedi side connector. I've looked at the service box schematic and any other info the I could find on The Google, but I can't find a decoder ring that will describe the means to enabl...

Coming in Thursday afternoon, flying out early Saturday, got family stuff early Sunday.

I'll Be on 900 ham. Bringing a coupe EFJ-5100 P25 radios to sell, VHF and UHF.

willbartlett

Gonna be there Friday and Saturday afternoon.

Batmeal Friday would be good. Got out early enough last year to miss the code brown.......

Will

willbartlett

I'm in. There Thursday afternoon to Saturday afternoon.

I'll be on 900. What freq is the vhf quantar on?

Will

willbartlett

You could but the list of modifications is longer than the maxtrac flat audio mod. IF you could build or a reliable 4 level decoder, AND implement the FEC, AND cleanly apply that to the modulation input for the exciter, you would be most of the way there. but you're talking about building a decoder,...

So, silly question. I have an OLD trn7760A rev. I only have back to a d rev banual. I see the jumpers for setting the ID bits for a trn7475. Can anybody enlighten me as to what the jumpers are on an A rev board. Past that, will the board register as a conventional capable board after that, or would ...

willbartlett

Yep, In all of the exciter and PAs I've looked at, at least VHF ones, it's a resistor array feeding a mux that gets reported back to the SCB. In the exciter, it's one resistor to change the reported range, and in the PA, it's either the addition or removal of a couple of resistors to change it. Then...

willbartlett

The Nucleus exciter will indeed pass audio. However the only audio path deals with what would be called VCO Modulation (VCO MOD). It's missing the other path called Reference Modulation. The REF MOD is needed for the low frequencies (DPL and some PL) because the synthesizer and VCO will try to corr...

willbartlett

So, Having played with some of this, here is what I know: You can port all of the boards from a 900 quantar (analog only) minus the 100w PA into a 300w NUC frame, and it will try to repeat. RX works fine, the exciter will attempt to tx, but the SCB doesn't know what to make of the 300w PA and second...

willbartlett

Not to revive an old issue here, But I have something very similar going on here. My station seems to reset every 1:28. I get an error of: 1900/01/15.22:50:58 1 SC ROOT 665 SYS_RESET 247 1900/01/16.00:18:45 1 SC ROOT 665 SYS_RESET 248 1900/01/16.01:46:31 1 SC ROOT 665 SYS_RESET 249 1900/01/16.03:14:...

willbartlett

In for Friday and Saturday A.M. Need to be home for Sunday A.M.

I'll put the 5100 on 151.88 this year.

Call Rich at Amtronix. I have dealt with him over the years, as have several of my friends. Talked with him Friday at Dayton. Knows his stuff, reasonable rates too. If you're referring to the Casting under the front, It's probably a replacement, but Rich can let you know more.

Will, N1PXA

Hey all.

I'm there Fri and Sat. I'll listen on VHF. also on the wa1nvc 900 repeater, I think it's .5875, 131.8

Will

willbartlett

So I'm clear, the deadline was march 31st right?

Shame, I have 6 radio I just got hold of with this issue...

While my knowledge of the PURC 5k is nowhere near encyclopedic, I don't believe I've ever seen that feature in the menu system, and I've dug around a fair bit. I have a UHF PURC with a Micor RX tray as a repeater, needed to add the PL board externally. Just like scanning repeater in an MSF5K CXB, Gr...

willbartlett

Hi All. Was a scanning repeater function ever realized with the MSF. I believe there is reference to it, just wanted to know if it ever was implemented or available?

Will

willbartlett

Got it. I was confused by the fact that my boards have J12 as an A/B jumper. Pulling it and moving the 0 ohm resistor to the pads halfway between u4 and u2 got me to 10mhz. Thanks again, and I hope you're feeling better.

Will

willbartlett

Hey there. J12 is on the board marked in silkscreen, but the other 4 are not. I can see 1 0 ohm SMT resistor, and a couple other pads. If you can scan that in and send it. it would be greatly appreciated.

Will

willbartlett

Looks easy enough to decipher. I'll try it tonight and get back to you if I have no luck with it.

Many thanks, Will

willbartlett

Hello All. I have a TRN7408 in a VHF PURC5K. It has a 5 mhz OCXO, but I'd like to move it to 10Mhz to use a GPS disciplined reference we have available at our site. I only see JU12 which seems to switch the REF frequency from 5 to 20 mhz. If there another setting somewhere on the board that will all...

willbartlett

I'll be there Friday only, got to be home Friday night for another trip Saturday. I'll be on P25 uhf, and 900. There will be at least one 900 repeater onsite, details to follow. I'll check in on 446.925. Are there any VHF p25 ham frequencies in use?

Will

willbartlett

Do you guys think we really need to re cap the machines if all the caps look fine. I looked at my machine very carefuly and nothing is leaking. WIll new caps really allow for better audio even if they look fine? If you don't have any leaky ones now, you might be alright. I just brought it up as I h...

willbartlett

Hey All. For the budding MSF5000 owner I present the list of capacitors you will likely feel compelled to replace once you notice the green crud climbing down the leads to the board. My amounts represent repairs to 5 of these with a bunch of spares left over for my parts box. Actual count per repeat...

willbartlett

Haven't gotten there yet. I just got a pile of manuals yesterday. I know the UHSO tray stuff is in there. I'll try to get some of it scanned and up over the weekend. Also, the Jumpers listed in the manual to change over to 10 MHZ are different than what I worked out. I'll update them too. I did dig ...

willbartlett

I think if you look at the datasheet for the 7805 and 7812, you should see an example sheet. It will include some capacitors. I would follow this as an example. The better filtered the power supply going to the oscillator, the happier you will be in the end. I would strongly advise against using a P...

willbartlett

Dave, thanks for the info. The board I have is different. I have 9 jumpers. I got sick of having the tx portion of the service monitor dedicated to reference duty. I started an iterative change of jumpers, and after I don't know how many steps, finally came up with jumpers 2, 6, and 7 installed for ...

willbartlett

Dave, if you could look up the jumper settings for some of the other frequencies, I, and a lot of other people, would be eternally grateful.....

Will

willbartlett

Tony, check in the service manual, if that's what you have. I saw reference in my installation/alignment manual to a 5/10 mhz reference from the HSO shelf. I looked at the board inside the shelf, TRN9910B, and there are a string of jumers. I think we can make these run off 10 MHZ. only reason I want...

willbartlett

Good call. mine's fixed now...... I looked at the usual chip document sites, and X9503PI brings up nothing. Google it and all the discontinued chip suppliers, who have all copied each others listings, bring up a part # but no description. americaII.com doesn't even list it, so there's probably no ho...

willbartlett

Will, have you found a fix for the TX and PL audio.. i'm still working on mine, there is no audio on the transmitter its not getting sent to the along with PL or DPL Tony NN1D No, Not yet. I have one of the MSF test sets plugged into the 40 pin header on the top of the controller. I can hear the RX...

willbartlett

10 MHZ is a no-go. Too bad. In addition, there is a regulator board present in the PURC5K HSO boxes, so you'll want to breadboard something to regulate to 12v and add a significant amount of EMI filtering as well. Common and differential mode would be advisable. I'll try to get pictures and schemati...

willbartlett

I'll second that. Many thanks to Tony, all the south shore guys and definitely the PSE+G people. Sorry I couldn't stick around for breakfast, but I needed to get the truck back to my friend and get my daughter after pre-school. I took the hutchisson/merrit back past the NY border and it was a beauti...

willbartlett

the first unit I powered up seems to be fine. I stuffed 5mhz at .99v from my service monitor into port 3 on the side with the bnc. All the error codes disappear. station will key but I don't have a bird element that will read that high. I'll be looking at more during the afternoon. doesn't look like...

I just flew out of sky harbor yesterday, Made a contact (weak) through Mt Lemon to a ham in Tucson. Nice propagation when you have many thousands of feet to work with. The White Tank VHF ham machine always impresses me. I've listened to it in Yuma and Quartzsite. Worked into it from as far west as D...

willbartlett

Hey All. I'm looking for station manuals for both VHF and UHF Purc5k. Primarily interested in the rf drawer portion, but a full manual would be outstanding.

Email if you can help.

Will

willbartlett

I have a spare HSO from a Purc5K. If you are interested, drop me an email and we can work something out.

willbartlett

Can somebody email me the modification documents,and any info on the 36-42 to 10m conversion info too?

willbartlett

I don't know what other needs you have for it, but an hp 8920a or b, is a pretty nice unit to have. In addition to the spectrum analyzer, it does support a tracking generator for some basic scalar network analyzer use, plenty for tuning duplexers. I've done a bunch with mine, no complaints at all. I...

Man, I wish I'd been paying attention to this thread last fall. I had a half dozen of the Glenayre 1/4 kw 900mhz amps in my basement. I think I gave away the las one a few weeks ago. I can see about reclaiming them, might not be too troublesome. If I can come up with 2, I'll offer them up for the pr...

willbartlett

As for the rest of the comment. The Hamsexy folks always come up with good stickers to hand out at Dayton. I was thinking somebody would have come up with a sticker that says something like "I've been WHOREFLASHED" or something equally fun. Like the Skyporn stickers, ya know?

Will

willbartlett

Also, does the litle round sticker say "I've been FLASHED" or am I missing something. Sounds like a strong cantidate for a Hamsexy photoshop. Perhaps they can figure something out for Dayton next year. Booth babe type of stuff. Give CES a run for the money. Plenty of time to mull that over...

200mhz low pass. +27dbm max. Who Knows. Must have been for something full duplex. I can't think of any other reason. I haven't looked at a spectra amp schematic in a while. Maybe it goes directly to the RF board. Most likely there's a low pass as part of the PA section and they needed to maintain em...

What is the part # on the cylinder. It's a mini-circuits part, filter probably.

Sorry for the off brand question. I have a couple of vhf Stealth 25 portables, and am looking for any definitive info on setting them up for the equivalent of MOT digital carrier squelch. I've tried entering a nac of 293 and 7fe with both a tg of 1 and 65535. No dice. It decodes p25 in monitor mode,...

willbartlett

Host/dsp mismatch? I have one that does this too. The Vocorder will work in other radios, but No audio, including status beeps, when it's all together. Is it an Ebay radio? Possibly pieced together? I've tried other cases too.

Will

willbartlett

If you can find the same part # in an HT1000 or Astro Saber board, It'll match.

Good luck, Will

So I was going through this box'o'mics I have and came across an hmn6062A. It's dark blue/green with a off-white grill and a blue logo. Body type is the same as a Micor mic, connector is a 5 pin cylindrical. At a minimum, I might put the case on my astro spectra mic, you know, to look 'cool'. Anyone...
