I have just had to re-enable the serial port on my Thinkpad 380XD and had to search again for the instructions.

I remembered that I posted info on the Batboard but I can't believe that it was exactly 13 years ago!!!!

I just bought the 6 pin mics to add to my collection...they were brand new and I was assuming that they were 8 pin type...but they were only a few $ each so I could not resist!! I have a big "collection" of Motorola radios (and mics) so the 6 pin mics are not a problem :)...and no I would ...

I have a 6 pin RJ11 Motorola mic. I know I can use an 8 pin RJ45 mic plug with a radio 10 pin mic socket (as the pins line up excluding to 2 outer pins on the 10 pin RJ45 socket which are not used or not applicable). So can I use a 6 pin RJ11 mic plug with a 8/10 pin RJ45 radio socket? I don't have ...

I have an ex-demo Motorola Lex L10 "mission critical" smartphone which is hanging at the "Motorola Solutions" boot up screen. The Lex L10 is a smartphone with a PTT and can be bluetooth linked to control a Motorola APX series radio as well as having all the usual smartphone featu...

Have you ever used the Triton RSS to program additional channels or align the radio?

g8tzl2004

I have a VHF GP68 radio. I have lowered the "User adjusted" squelch setting to "1" using the front keypad function but the threshold is still a bit high for very weak signals. Does anybody know if the internal squelch threshold adjustment is via the tuning RSS or via a PCB pot? I...

No zapping required with the 22 year old GP300 battery!! I could not find my "fast" GP300 charger so I have been using a GP300 "10 hour" charger and the battery seems to be charging OK...with a voltage while charging of around 8.6v....so all the cells are OK. The radio scans for ...

g8tzl2004

I have quite a few 10 - 15 year old Saber, Jedi and Waris batteries which still work OK..maybe not 100% original capacity...but the charger lasts about 45 minutes before the green light..so the batteries are taking quite a bit of charge!! With "new" old batteries I have found that it takes...

g8tzl2004

My "new old stock" Motorola Triton MP100 arrived today. The radio is mint in its box and was manufactured in 1997. The battery is a "Made in the USA" FM / IS "GP300" battery and was also manufactured in 1997. After sitting in the box for 22 years, the battery voltage is...

g8tzl2004

I did some more searching and RSS is meant to exist but it was only used in the factory...so maybe it was DEPOT or LAB RSS?

I also read that very early versions of GP300 RSS is meant to work but you need to "trick" the GP300 RSS somehow?

g8tzl2004

I have a Motorola marine VHF portable - its a Triton MP100 which looks like a GP300 display version but with dedicated "marine" keys such as channel 16 etc The specs says it can operate between 146 - 175 MHz. Does anybody know if there is a dedicated RSS for the Motorola Triton marine port...

g8tzl2004

I've checked out the VHF Systems Saber and its TX/Rxing on 147MHz on every channel!! I read somewhere that you can only program the Sytems Saber +/- 1MHz out of band...which might fit assuming the official band edge is 148 MHz...so maybe the previous owner tried to program the radio below 148 MHz bu...

g8tzl2004

I now remember that there is both a Saber and Systems Saber!!...2 different radios

Anybody know if its easy to program a VHF Systems Saber down to 145.000 MHz?

My standard Sabers program down to 145MHz no problem.

g8tzl2004

I have recently acquired a VHF Systems Saber H43TUK5170CN I've checked out Batlabs and the model number does NOT appear to be a version as listed on Batlabs. There are a few mentions on the internet but not much. Does anybody know whats special about a H43TUK5170CN I'm guessing that its a 25KHz rath...

g8tzl2004

Assuming a mid-range loss of 21dB relative to an isotropic, I think this suggests that 6W from a low band HT750 is effectively 30mW given the losses using the helical!!!....and an isotropic is 2.15dB greater than a dipole...so relative to a dipole its equivalent to around 20mW!! So 20mW using a low ...

g8tzl2004

Interesting. The speaker mic cord must be acting as a ground plane and affecting the SWR!! A 29.6 MHz 1ft helical with no ground plane must be very inefficient... I wonder how many -dB's compared to a dipole!! I have noticed a massive improvement in RX on higher bands such as 6m when you simply rest...

g8tzl2004

You wonder why Motorola makes 4 different versions of the low band antenna when they probably all need to be cut!!!...although I guess its cheaper to buy a 42 - 50 MHz vs 30 - 36 MHz antenna as there is less "wire" and "rubber"

I guess the uncut version is ideal for 29.6 MHz!!

g8tzl2004

OK thanks. So the antenna could be an aftermarket NAB6063 with the red color code...which fits with Motorola cutting chart giving 47 MHz. When you buy a NAB6063 42 - 50 MHZ, can you use this antenna to TX/RX anywhere between 42 and 50 MHz without cutting the antenna to a specific spot frequency....s...

g8tzl2004

I have a helical antenna with a red color code on the screw thread. It is about 7.5 inches long and 0.5 inches wide and does not taper There is no "Motorola" logo. I looked up a Motorola cutting chart and it indicated that the antenna had been cut for around 47 MHz. But I'm not 100% certai...

g8tzl2004

Thanks...yes I checked out the basic SM which provides details of disassembly...but, as indicated above, in the "line up" diagrams, it shows the knob attached to the volume pot rather than "clipped" to the front panel...so it did not appear that you could get the knob through the...

g8tzl2004

OK thanks

g8tzl2004

Thanks kcbooboo and jackhackett.

Just so I'm clear, the LCD will stay attached to the circuit board with its plastic clips when removed from the head OR does the LCD stay attached to the head when you remove the circuit board from the head?

g8tzl2004

Thanks Jackhackett is the LCD assembly not soldered to the PCB but just rests on the PCB when everything is snapped together? The service manual shows a picture of " how everything lines up" with the knob attached to the pot shaft on the PCB...is this wrong...the knob should be attached to...

g8tzl2004

I've checked out the service manual on dismantling the CDM...but can you just remove the plastic front leaving the control PCB and LCD in place attached to the body and then just remove the silicone button assembly to enable the PCB to be cleaned. Or do you need to remove the entire control head inc...

g8tzl2004

Thanks jackhackett. The CDM radio looks mint so could have been in a repeater enclosure but as you say, why would it have all the on-board UHF marine simplex and repeater freqs and zones programmed rather than just one repeater freq. I'm pleased that you are now focusing more on radio rather than dr...

g8tzl2004

The radio is ex-marine so could have been used as an on-board ship low power repeater - so maybe its using some kind of modded repeater firmware which causes the down arrow key to act as a Zone toggle key?

g8tzl2004

You can program 4 front keys (P1, P2, P3 and P4) with numerous options but the up/down/left/right arrow keys are not programmable.

I have programmed P4 as a Down Arrow key so I can use that instead of the actual down arrow key

g8tzl2004

Thanks kcbooboo. As you say, its probably better to try a known good head. There is no option to actually program the down/left/right keys so that they will perform other functions...so the fact that they all operate as if they are Zone toggle keys is odd. I don't even think there is a Zone Toggle o...

g8tzl2004

I have a CDM1550 (GM338/GM360) where three front keys - Channel down arrow key , Left arrow key and Right arrow key all act as if they are programmed as a Zone Toggle key. When you press any of the 3 keys, the zones toggle up/down rather than eg channels scrolling in a downwards direct if you press ...

g8tzl2004

My PSU is rated at 25A so should be OK. The TOT was originally set to 60 secs. The radio was also originally running around 50W with a TX output setting of "100". I lowered this to "50" but still got the power burst effect...but maybe I need to realign the whole TX stage...but th...

g8tzl2004

Thanks for the feedback. I lowered the TX power (from 100 to 50) but still get the "power burst"....and I assume its still Txing "in band". The radio was from an SK sale so nobody to ask about its history. Maybe its a "36 - 42 MHz" radio...but the radio still had 31 - 3...

g8tzl2004

I have acquired a Low Band Maxtrac which currently RX's/TX's around 31 - 33 MHz....so should be good for 29MHz. The RX side works OK. There is a problem with the TX. When I press the PTT I get 50W for a fraction of a second and then the power rapidly falls back to mW's over a 2 second period. If I p...

g8tzl2004

UPDATE: I have successfully warped my 5.4KHz off-frequency Saber back onto frequency..within 60Hz It looks like the previous owner had maybe dumped another CP into the radio but had pressed "No" rather than "Yes"....the wording on the RSS is not clear (see posting from 6 years ag...

g8tzl2004

Did you use an OEM Motorola programming cable or just a standard micro to USB A cable?

g8tzl2004

Maybe the radio detects that an non OEM charger is attached so gives the warning to encourage users to buy an "expensive" OEM Motorola charger :) But maybe there is a 5 minute timeout on the warning :) Is the OEM charger identical/similar to a real Motorola micro USB cellphone charger? Has...

g8tzl2004

I got the SL300's real cheap from a junksale - seller must have thought that they were FRS type radios - they sort of look a bit like FRS radios but are actually great performers. However the radios did not come with an OEM Motorola micro USB charger...but USB chargers are meant to be "standard...

g8tzl2004

I am charging my SL300's using a standard USB charger (5v 2A) but not an official Motorola charger....actual one used to charge a tablet PC so plenty of current. The SL300's charge OK...BUT I have found that if I have been using the SL300's, if I power down and immediately connect the charger, I get...

g8tzl2004

Thanks RFI-EMI-GUY. OK on maybe the radio had had a codeplug dumped in but the tuning values of the other radio were retained rather than the tuning values of the actual radio. I checked my notes from years ago and it was an easy mistake to use the wrong tuning values...the RSS wording was not at al...

g8tzl2004

I used a frequency counter to measure the Saber 3's TX frequency. I checked the frequency counter using 3 other radios which are all +/-200Hz. My frequency counter has not been calibrated but its within a few hundred Hz...the Saber is 5400Hz off frequency (10x more than "acceptable")...wea...

g8tzl2004

I have a UHF Saber 3 which is 5.4 KHz off frequency. I have had other Motorola UHF stuff such as MCS2000's and MTS2000's which have been 2KHz off frequency and have warped back onto frequency OK....I guess the TXCO crystal has drifted over the years...and the drift is always greater with UHF stuff.....

g8tzl2004

I have a DTR650 which has a stuck PTT micro-switch. I've "manipulated" the rubber PTT cover and the PTT micro-switch has sort of released and if I gently press the PTT it will release OK when I stop pressing. But if I press harder (as in normal use), the PTT micro-switch still gets stuck a...

g8tzl2004

I used a damp cloth and rubbed real hard and eventually the white residue started to come off...I got a black residue on the cloth which I guess was the top layer of the rubber. I think the black rubber residue left on the cloth provided a bit of abrasion which helped get more of the white residue o...

g8tzl2004

I dug out my DTR650's the other day and the outer rim of the body (basically the entire top, bottom and sides) was covered in white residue!! It looked like it had been painted white!! I've seen this on Motorola antennas...but it was many times worse on the DTR650's...much thicker residue . Any idea...

g8tzl2004

I believe you can just use the standard programming cable to access Service Mode and then adjust the TX frequency. I just Tx'ed into a 2m antenna positioned near my portable frequency counter....simple but worked. You adjust the TX frequency using the software...press an F key (can't remember which ...

g8tzl2004

Thanks.

How do you do a CH sync?

g8tzl2004

I have a remote mount 110W VHF XTL2500.

Can I use the remote head from the VHF 110W radio on a 50W UHF brick without doing any firmware updates or option updates to the head (or brick)?

Or does the remote head contain firmware that needs to match the brick firmware?

Thanks

g8tzl2004

OK thanks com501. It looks like the real Micom 2 hand mic for a "MCS2000" type head is a FMN1615A. This looks identical to a HMN3413 GM300 "all black" mic...but obviously is wired differently as per your warning. I think this Micom 2 originally came with "probably" the ...

g8tzl2004

Does a Motorola Micom (MOBAT) 2ET HF radio with a remote head (which looks like an MCS2000 head) use a standard Motorola mic with standard pin outs?

Thanks

g8tzl2004

Does the Motorola online MOL "database" list the price as $20 or is the official price higher and resellers are discounting?

g8tzl2004

OK - cheaper than the fleabay copies!!!!

You would think Motorola would be charging $120 not $20!!!
