    Radius m1225 station found in the trash

    And I thought those days were over. I would sometimes dumpster dive behind a local com shop and usually came up with something. One time was after a clean house thing and got a bunch of mobils, Deltas, mocom 70s, Master parts and assemblies, Micor base, old service manuals, new in box desk...

    SDR# Mini-Circuits Amp for HackRF One Recommendations (1-5 watts)?

    Playing with synthesizers with +10 db output, I bought a 2 watt amp on ebay for $35. Claimed to have the mini-circuits device(really a clone) The +10 db is about all it will take to get the two watt output, more drive just causes an increase in the birdies and spurs. that is when an attenuator...

    Orion radios.

    ebay isn't worth it, besides, radios are a bit of R&D platform for me, a hobby. They just collect over time. Have half dozen rangers, several Deltas. Last count was 62 portables from the PEs to 7200. The really great radios are anything mastrII station. Everywhere I look is a Mastr II or III...

    Harris Unity Time Display

    The time comes from the GPS and of course has to lock. I have a couple Motorolas that take a minute til first fix and show time. Stays up unless loss of signal.

    Orion radios.

    Yes, very well suited for amateur, fairly easy to convert. Looks like I have all but the 136-150 split.

    Harris ROP101692/CR3A CPU info wanted.

    I am hunting for any information at all for the Harris ROP101692/CR3A brain. At least what specific core or cores this chip is built on. I have pin functions for the QFP but that is all. I know this is an obsolete chip, why documentation is unobtainium, but I have reason for this. Thanks all 73s

    Which radio(s) is this rfguys programming cable compatible with?

    I can't rule out a bad cable, but before you condemn it, the contacts on my 7100(and 700P) are recessed a little. Maybe get rid of the rubber that hits the frame. That should let the pins make good contact. If that fails, then you can scrap it. RF guys is the only 3rd party vendor I know of that...

    Which radio(s) is this rfguys programming cable compatible with?

    When I say tighten the dung out of the connection that is seriously what it takes. The rubber boot over the pins holds the pins too high on the radios. I question your OEM cable being for the P7100. I no sooner submitted my last post when I found my circuit board for the UDC, the board from a...

    Which radio(s) is this rfguys programming cable compatible with?

    The OEM and RF guys cables are different but the pogo pin placement is identical. Pin assignments are identical. The difference in the shell and how it mates to the radio doesn't fit well and why the need to hold it in place when tightening the thumb screw. The fit on the LPEs is worse, start...

    Which radio(s) is this rfguys programming cable compatible with?

    That is for the M-RK, LPE prism series. (SKU 33950) The pinout matches Jaguar 700P, P71xx, P7200, P5100, P5200, but with these radios, you have to hold the UDC together. that or buy SKU 33176 (RS232) or 37176 (USB) from RF guys. While the keyloader cables look identical, the "R" sense is...

    Orion radios.

    Wondering what I would do with all these Orion radios I stockpiled, I looked to other uses. Orion radios, 1001 uses. Besides doorstops and anvils, they make good jack stands also.

    Provoice being discontinued ?

    Yea, well how about a break. I am an old guy trying to recall the 30,000 some odd acronyms exclusive to Harris. Everybody is different. Add going blind and typos come easy for me. You are going to hate growing old yourself. Lets just leave it at provoice will be around a while, just no longer...

    How To Adjust Squelch Tail on IC-FR4000

    Sounds a bit like an old repeater I helped build up for ham service. Seems the CWID sits dead until it activates and only robs the repeater at that time. Turns on TX if not already up and just inserts modulation. Using DTMF to bring up the repeater is a separate control configuration, but...

    programming issue

    Yea, I do that a lot, especially with Erisson. Might be easier sitting down with the programming manuals, do a worksheet and program from scratch. All the major and minor platforms have their different how to's. Sort of a learning curve. One successful codeplug will be like 'well that wasn't so...

    Provoice being discontinued ?

    I have one M-PA with P-25, just have to have the memory to support it. LTR= Long Term Revolution, nothing to do with it.

    Provoice being discontinued ?

    I see you have no clue just what LTR is. Yes, they are as different as night and day.Pretend LTR was never mentioned.

    Old school question C800-900

    Give me the model/part number of your control unit, I likely have documentation for it. This document at least has options combinations listings by part number.

    Old school question C800-900

    Master II can be configured with just about every control head earlier than the Orion series. The heads are programmable, maybe look up programming reference manuals and SRNs Dig up the matrices documents, that can tell you where to look.
