While I can't make those radios wound work in my car (I might use NX-5700/5800 radio). But the XTL5000/2500 would work at home. This is my next project. But I think I need to find a local expert I think...
Thanks for the help everyone...

So If I choose two heads (one each for VHF and UHF), is there any other reason that a XTL-2500 wound not work (what would I loose), Vs the 5000? Would this one work OK for example? M21KTM9PW1AN Whats the difference between a M5 and 05 Heads? IS there an option to program a button for hi/low RF PO? R...

The problem, as far as I know the XTL5000 are not supported any more.

Sounds like two heads are better than one. I'll have to rethink my options. I need at least, that the Aux radio scanned, full-duplex is nice, but not required.

A weird Idea maybe. Idea better if your a HAM too... Use two VRS one on VHF one on UHF (revers of the radio connected). To receive them at teh same time. Use a HAM duel band, duel receive, HT (since there is no commercial radio's that do this) - Or use two commercial HT. This would require effort to...

I am considering buying a used XTL5000 for P25 and wide band FM (5kHz), and some commercial use. I need 144-148, 440-450MHz, beside the commercial bands around them... 1) What do I need to look for to do the above? 2) What radio programming software do I need (version)? 3) If duel deck, single head ...

Is there list somewhere of what is actually needed to make the 5000 work in this duel band mode?
Software and hardware?

With the XTL5000 it works both radios can transmit? Should I restart this subject in the XTL-5000 forum? For HAM use such as, wideband FM, and P25, are their other issues? Is there any reasons that a XTL-2500 cant be used? My long term goal is ether buying new NX-5700 duel radio with P25 (too expens...

So the XTL500 can? What hardware is needed?

Bummer.
I want a P25 and FM transceiver, and have a small car. Not much room left over for two more radios. I wanted to look at what available used older radios that I can afford. XTL are right on that line. The only real option is the Kenwood NX-5700 with duel radio. But thats too expensive.

OBTW. And yes the noise floor issue is real bad in many places...

I inspected the small tab NMO coax kit. I did-not find any issues. The Larsen large tab NMOKHFUD did the trick? Anyway, I agree the NMOWBQB and a long black whip 56+ inch whip is a good antenna. The problem is finding the 56-62in whips, especially the black ones... Recently, I found a new antenna th...

OK, dual is what I meant.

What I was asking about is W9 head and two trunk transceivers, one VHF and the other UHF.

Is there a Spectra Astro, duel radio option (RX/TX for both)? When using duel radio, is duel receive an option, or is the other radio just more channels to scan? Is Wide or Std Dev FM possible (ham use)? I am interested in the Astro because of P25. Can any head be used? Are there gotchas? I know abo...

Hi all; I installed the large tab NMOKHFUD coax kit, in place of the one with the smaller center pin. WOW - What a difference!!! Problem solved. Now I have 1.3 SWR (~48 MHz) at residence. And after pruning, I have now 1.4 SWR on 47.xx MHz, and 1.6 SWR on 52.525 MHz, the highest likely to transmit on...

Thanks. Lots of heaving reading there. I was hoping someone knew of a simple fix.

I too find this interesting and thanks everyone. Food for thought about my X9k on LB, that wont lock below 33 MHz or whatever it was...

Jim202,

Especially when you have 128 or more modes. Been there done that.

I have a FT-857d and it covers approx 1.6-33 MHz, and 33-56MHz, RX/TX after changes are made.

Around here in the Bay Area/ Monterey Bay Area the noise floor for 10-6m is quite high and even on 2m/ 70cm, its bad. It seems to be broad band interference. Sometimes it does not register on the radio S-Meter, but is heard on the repeaters signal. S9+40-60db and there is static on it? Anyway, I thi...

Hi,

I really like the Syntor x9000 radios. However, they do have the lower 250 Hz to 500 Hz muted it seems. My FT-857d has fuller audio, that someone listening on a Syntor x9000, can even here. I was wondering, if anyone knows of a sw or hw switch to allow more lows through the mic circuit?

Copy.

I dont know what tl;dr is?
Bummer about the grounding part...

OK. My bad. I knew about the grounded hanger thing (HUB). But I thought that the shell of the hanger was ground and the tip of the hanger was HUB. When you hung it on the mic clip, it shorted the two, and then it was in coded squelch mode. It appears, this is not the case for the mics I have. Are th...

Hi all; I just found I have a Syntor X9000 that's always in Carrier Squelch? I Thought that what the possibility I've never noticed. Unlikely. I decided to try one more mic (I had tried two, one had no mic audio), on the 3rd mic tried the mic on hook gave proper muting. What's the chance, that 3 mic...

Here is my list: Residence (MHz), 2.0 SWR BW (MHz), length (Inches total), and type and brand ------------------------------------------------------------------------------------------------------------------- 46.0, 42.0-48.0, 55.5, NMO, Larsen wide bandwidth 40-50 MHz Antenna.

Its I think common that ~150 MHz, 5/8th antennas work on 6m as a 1/4-wave. I did some testing tonight. I dont have time to write it up now, but I compared several antennas, commercial and some made by me (NMO to 1/4 wave whip with a spring). No field strength test, just SWR. The misquotes were real ...

Guess what I have already sitting on my desk for my own install NMOKHFUD. I plan to try another tow antennas on her roof. But a new NMO mount might be in order. If the next antenna works (a Child's antenna, 5/8th duel band (and yes, it seems to work on 6m quite fine (more testing needed)). If not, I...

Hi, I have a NMO center tab size question (an antenna problem). I've heard over the years, that some size MNO center tab and bands don't work well together. Is this true? Is there a white paper or some sort of documentation out there (link please). I've google the subject and not found anything. I h...

The new radio I bought works down to 29.5 MHz at least...

It made spec in-band at 0.4uV, so 0.45-0.5uV in the 927 MHz is to be expected, I guess...

PS. I have just the LB manual...

I decided to purchas another radio. I'll work on the bad one on the bench...

I have the manual. I dont see any VCO adjustment. There are very little tx alignment for the x9k. Worp, Dev, Comp, and several RF power setting related to OP and protection. Thats it.

I normally start with the manual, then Google, then asking questions on forums...

Update...
I programmed 29, 29.5, 30, 31, 32, 33 and 34 MHz. It only transmitted on 32-34 MHz. I used v5.02. I made a fresh code plug from scratch.

Good news. I got the antenna system working. The 47-52 MHz side needs slight tweaking, otherwise works fine (it shifted down in frequency, and now 52.525 MHz SWR is close to 3.0, it was around 2.0). Bad news. I have no positive idea what exactly changed. I found that the spring was loose on the moun...

George wrote:I used the dual antenna arrangement for years with Spectrum antennas on 29.6 and 52.5 with no issues. The coax lengths are great for a car with a full sized trunk and the drawers mounted on the right side.

I assume your antennas ware loaded antennas. Mine are 1/4-wave whips on ball mounts...

I redid the set up with new belden RG-58U coax. Same out come. No good. I plan on adding few different patch cables of different lengths and see what happens...

Well My MCS2000 on 900 MHz is kinda deaf at ~0.5uV; While my Specta 900, is ~0.25uV approx...

I'm not an expert on Spectra Astro's, so I might have some of the jargon wrong:

I think Mot thinks they own PTT too. They better hope I'm not a Juror on that case...

I didn't find an alignment procedure for the PLL/Synth.

Hi all; I have a Syntor x9000 on LB, that has no output on 10m (29.5-29.68). And there is no current draw. It works fine in the 40-53MHz range. I thought I read somewhere about going to the lowest used frequency and checking a PLL voltage and if needed readjusting the PLL. I know I saw something abo...

Nothing like responding to a 4 year old message, right... Anyway, I too have MCS2000, it has slightly more poor sensitivity on ~927 (0.45uV) and was also tested on ~935 MHz were its better, but still just about 0.40uV witch is as specified. Anyone find a fix? If the early radios were better, there i...

Motorola charges full price. I was looking for a more affordable source.

Is there a good low priced place to purchase X9000 buttons?

The Parts radio now lives. The no TX was do to a bad personality board (if you remember, I purchased this radio for parts and I needed the personality board. But that board had many wires bypassing bad traces). The replacement board just needed (JU) jumpers moved to make it good for LB. And I needed...

The MCS2000 on 900MHz must be the aberration. Its spec'd for 0.5uV and thats what I'm getting. Its the worst sensitive radio I own...

The 10m antenna is brand new. The 6m antenna is recycled and spring is rusty. But the SWR is normal on it. I'll check it...
BTW. I went shopping for smaller spring and found that its become common that do to cost cutting, the braid has been eliminated (unconfirmed).

Do to a lack of response. I'll assume that the two coaxes are different. I'll go find some RG-58U (both are 0.66Vf), and start over.

Bad news... It did not work. The coax is 58A/U, clear not foam center conductor coax. 105in on the 6m whip, and 46in on the 10m antenna. Also, I found that the PLL (I'm assuming) is not locking, no 29-29.68 MHz output. This was a SWR test with radios transmitter... I tested it on 48 and 52.525 MHz ~...

OK I see. I think, that the currently not used antenna is either a short or an open. The 10m 1/4W on 6m is a 1/2W (approx) for 6m, this is 500-1000 Ohms. The 6m antenna is 1/8th wave, this is more like a short i suspect. These are my best guesses... Any way, I cant wait to see how it works and over ...
