Page 21-30 contains a part list Page 52-53 has a diagram that includes the part numbers to aid the search. The radio body or complete system can be found on ebay ranging from $300 (brick) only to $1000-$3000 depending on the head style for a complete system. I chose to buy the bricks and components separately. You can buy an older complete 7300m/5300m/75M for about $120-150. Double check the part numbers from those radios, to verify what parts carry over. THE HEADS and Mounting Refer to page 18 of attached manual from first post for pictures of the styles. CH721 Head- Avg about $60-80 on ebay. Part# CU23218-004 (system head) Part# CU23218-002 (scan head) This part can be a carry over from a 7300, 5300, XG-75M CH721 Head Remote Mounting Bracket I opted for the remote head bracket, which may be changed to the ram style home brew mount copying the Harris mountU Shaped bracket Remote Head U bracket Part# KT008608 Avg Price new on ebay $10 + shipping CH721 Head Remote Pedestal Mount Part# MACDOS0012 Would love to find one but haven't, probably will have to DIY something similar CH721 Catalog numbers Ch721 scan head remote # XMCP9E console mount # XMCP9G CH721 system head remote # XMCP9F console mount # XMCP9H Ch100 remote mount # XMCP9H console mount # XMCP9Q CH100 Touch screen, bluetooth head Part# 120991200-01 Avg $1000-$2000 (new) Highly sought after but crazy priced. allows for bluetooth programming allows for system/configuration changes that are unavailable on any of the other heads., CH100 Head Remote Mounting Bracket Part# 12099-1500-01 Avg $60 new on ebay CH100 Head Remote Pedestal Mount Part# 12099-1501-01 not sure if you need the above as well as the CH721 Pedestal mount. Refer to Fig 8-9 on page 59 to understand what I am saying. Remote Brick Bracket Part# KT23117 I chose to use part# fm103111v1 We will see if it works fine. Probably won't have the screws, but it is the part number that is included with the kit I couldn't find the kit AVG $18.99 for a beat up one Console Install bracket Part# KT101533V1 Avg $15-40 You can do multiple head setups. A pair of CH721s, a pair of CH100s. You can not mix and match a CH100, with a CH721 head on the same system. This is much like trying to use and 03 head with a 05 head on an XTL series Motorola radio. XG-100M00-1470305.pdf

Trying to compile a list of parts necessary to build out an XG-100M. Nothing more at this point. The Radio: XG100M VHF low band 30-50 MHz 9 miliwatts Some agencies around DC suburbs still use VHF low Shenandoah PD Maryland state on the western handle of MD couple of others It CAN NOT transmit on the ham bands Filters are to tight VHF High 136-174 Wide/narrow 5-50w UHF 380-520 MHz Wide/narrow 5-50w UHF 700-800 MHz 2-30 w 700 MHz 2-35 w 800 Mhz P25 Conv., Trunked, 12.5/20/25 kHz spacing Modulation Phase 1 TX: C4FM, RX: C4FM & WCQPSK Phase 2 TX: HCPM, RX: WCQPSK DVRS (digital vehicle repeater) available for 700/800 Mhz only

Should add. Yeah, I know about some of the memory/cps hacks to get some models to open up. Prime example is my XTL5000 it is an R2 "s" model. That was cps reconfigured to a quasi "Q" spec. With a CPS hack/hexedit. The older harris radios some could be reconfigured "opened up" to transmit outside of their original band, using "sc" files. Initial research is showing not possible with the XG-100M/P series.

Yeah, mxdn is pretty much unavailable in Washington DC area. One repeater in Arlington. Wonder if that repeater is as dead (little to no traffic) as a majority of the p25 repeaters in the area. Really wish repeaterbook wouldn't list some of these tiny repeaters (1 mile coverage) for personal use. You know the hotspots with a high gain outside vertical. I feel it kinda misrepresents the actual digital coverage. Sent from my SM-S901U using Tapatalk

I ask the boys when I have dinner with them next. 3/4 of them work with or are in the radio depots. But I know of no hacks for the mobile to open up the bands any more. Sent from my SM-S901U using Tapatalk

Agreed. I found the most traffic on 70cm yeasu c4fm, dmr and dstar. Rarely heard anything on 1.25m. Sadly, really wanted to, so I could look at those radios. Even with the popular digital modes not so many repeaters were set up for vhf. It was almost a 4-5 to 1 ratio of uhf to vhf. I looked into old motorola 33cm gear. But not many repeaters around here don't require either a 13cm or 23cm up/down link on rhe opposite side. Guess most of them were running icoms. Kinda frustrating. I thought of converting an old motorola flip phone for 900mhz.

So as expected, a 3/4 wave antenna just ain't cutting it. I tried out a Laird BB4503 (5/8 wave nmo). It out peforms the cut down signal stall in reception and transmitting everywhere (locations). This is stock and uncut. Originally, I was planning on cutting the signal stalk whip and putting it on the BB4503 after during some NanoVNA sweeps. I am not sure if I am going to be doing that with the new radio being installed soon. It all may be replaced with a STI flexi tri-band. If I decide to keep the BB4503 installed I will sweep the antenna and see if I have enough bandwidth without going over 2.0 SWR across 440-468 Mhz, At that point i will decide if I will buy a triplexer and install 2 more NMOs. So the decision has been made to put a tri-band in the location of where my 440-470 antennas are located. I wanted to keep it seperate but good god are quality triplexers for public service expensive. Not to mention it got harder to find ones where the band pass was wide enough to let ham bands through. The best one I could find was a Comtelco DB3 at about $192. Which was pretty wide banded. The STI-co which was another choice were 3x-4x the cost. The panorama ones averaged $160-300 were also pretty widebanded. I may try to utilize the signal stalk whips with the Tri-bander, kinda like I was going to with the 5/8. BTW, the 5/8 antenna is really stiff, we hit a parking garage support with the antenna and it sound like it was going to rip the back half of the roof off. Enough so my wife said we are bringing my car next time we come here.

Nice collection. So many dollars those Harris Prcs.. good god the prices that old Falcons still go for. Bragging rights,unfortunately in the group I spend time with goes to the APX 8.5k xe boys. Yes they own them as well as have ones that are issued.. But they are mostly FEMA or local FD. Wish I could justify nearly 5-6k for an APX, entitlements plus software and accessories. The XG100P is a nice radio, Fighting random reboots, but I think the battery might be done or has an internal short. I am going to be loaned another Harris Lithium battery and we shall see. The receive on the XG100P is actually pretty awesome, its better then the XTS500 I have. Even though the filters are pretty tight and the front end is no slouch on the XTS. I really like the radio and might actually end up replacing a bunch of hand helds. So much so I almost bit the bullet on an auction for one. But a buddy part of above said group. Coughed and said buy the XG100M(F) first while they are cheap. Welp... $440 dollars later and the XG100M is on its way with a CH721 head. Which means I will be ripping out my hacked XTL5000/05 that has been in the truck for less than a month. Would cost more to get the brick for the XTL5000 VHF hi-power. Really wish I could afford the CH100 head ($1900 still available new) touch screen and bluetooth would be awesome as well as a couple of the FPP features available. For those unfamiliar with the XG100M (F). It is a full spectrum mobile from Harris. It was designed for interoperability between agencies. So it has low band VHF which I don't think the APX mobile has, sure it is older then the APX mobile, but a lot cheaper then the APX XG100M VHF low band 30-50 MHz 9 miliwatts Some agencies around DC suburbs still use VHF low Shenandoah PD Maryland state on the western handle of MD couple of others It CAN NOT transmit on the ham bands Filters are to tight VHF High 136-174 Wide/narrow 5-50w UHF 380-520 MHz Wide/narrow 5-50w UHF 700-800 MHz 2-30 w 700 MHz 2-35 w 800 Mhz P25 Conv., Trunked, 12.5/20/25 kHz spacing Modulation Phase 1 TX: C4FM, RX: C4FM & WCQPSK Phase 2 TX: HCPM, RX: WCQPSK DVRS (digital vehicle repeater) available for 700/800 Mhz only

Bunch of little things. This radio was set to use system vs zones. Took me a bit to figure out I needed to create a conventional set first then I could add it the system. Bunch of little quirks like every piece of software. Like you can have banks. You don't program it like banka, then bank b. It just goes to channel #16 (bank a) #17 it's bank b. Not really sure why the gmrs frequencies were programmed into p25 conv frequency set and not to the conv freq set. I will have to ask the guru tonight at dinner. Sent from my SM-S901U using Tapatalk

Programming now over bluetooth. Slow and tedious because I don't know the software. But it programs fine over bluetooth. So no need for the expensive cable, as long as blue tooth feature is enabled. Sent from my SM-S901U using Tapatalk

So good news. As long as bluetooth is enabled on the radio it will pair fine with a computer. With two exceptions. Exception one the computer couldn't see the radio. A whole bunch of "unknown" showed up on the computer when scanning for bluetooth. Could be the computer. On the radio it saw the computer fine. So I paired from the radio, acknowledging from the computer. Done. Exception two, this is RPM 14. some of the pop-up dialog isn't scaled quite right. Cutting off some buttons. No biggie, worked in QA for years. Use to this kinda thing. Just hit "tab" till it looks like the left button is lit, then hit enter. That is if you have this problem.

What is often neglected is obstructions and elevation. If you are using a handheld it becomes even more critical. For instance, I can hit a repeater with a handheld everywhere in my house, but one spot, which coincides with a desk I use often. Turns out there is a building some 4 miles away that is inline with the repeater and the desk. Move over 2 feet and full signalling. First, see if you can listen to both the input and output of the repeater and see if there is traffic. Double check tones and frequencies. Triple check how far you are. If you know the general location of the repeater, get close and see if you can make it into the repeater. I usually try this when troubleshooting gets difficult to verify radio settings.

Most definitely. Too bad there aren't many options for APCO p25 in the amateur world. Mostly old commercial gear. Just depends on what you are doing and the quality level of gear you are willing to pay for.

Not at all. Since it's not my radio but "long/short term loan". Nothing really. My friend handed it to me with the hi gain antenna and lithium battery. Only thing so far would be a charger (about $80 with shipping for a used harris multi Chem from ebay). Maybe a programming cable ($100, used to about $400 new in bag). Software I am hunting for (probably about $750 if I need to order from harris). I have found new/old stock for about $1200 (no bat or charger) to about $1300 for a complete used set. You can find used ones without battery for about $600, normally $800. So if I'd go out and buy one I figure close to $2k. Still cheaper then an Apx. Do I like it more then the apx, no but it's 1/2 to a 1/3 of the cost. Big if would be finding one that was widebanded on uhf. Sent from my SM-S901U using Tapatalk

Waiting on the charger, currently. As well as waiting to meet up with my friend to enable bluetooth programming. Can't play with it much since there is a password set on the current mission plan. So can't edit the channels, not even the power levels. So apparently, there are three (3) banks to each zone. So 16 "personalities" per zone with 3 different banks to choose from. Essentially, 48 "personality" choices per zone.

Awesome. Will look into it. Using an unification g5 pager, lent from a friend on long term renta. Sent from my SM-S901U using Tapatalk

Rightfully so. If it was an apx8k series down right heart attack territory both in sticker shock and joy. Update. Spoke to the owner, will not let me borrow the cable, he uses on the xl series (newer line) as well as th3 xg series part of the reason they are expensive. He said he is very protective about his harris cables. But we will meet up to enable bluetooth programming. Configuration on the radio has to be enabled, so it needs the serial programming cable. I like this radio more and more. Till I can afford an Apx. Which should be in about 20 years. Sent from my SM-S901U using Tapatalk

Should note this. The radio when off the screen is white. I was concerned that it was damaged due to what looked like was streaking. In stand by mode, when the screen times out it is black. Powering on the radio it showed it was fine. Most of the XG-100P i saw when off were pretty similar, in one degree or another. Btw: screen photos in sunlight was with the back light setting set to 4 out of 10. So less then 1/2 of the available backlighting. Top screen is a white/black background, configurable in settings. *** top screen is not broken. That is a number 1 to identify current channel. *** Top screen has its own setting to reverse orientation and change backlight settings. No other customizations that I can see.

I agree. Better then some of my other radios. Even my 878uvii plus washes out sometimes due to glare. Screen doesn't look to be polarized with about 160-170 degrees of viewing. Didn't really disappear till the bezel was starting to obscure the screen. Completely viewable with my polarized prescription clip on sunglasses. Which I can't say the same about with most of my other radios.

Some Dimension pics. No scale to measure with or w/o the lipo battery. The antenna is the high gain long antenna.

Full sunlight pictures as requested. I think the black background helps. Motorola does the inverse with a white background. Keep in mind the screen is filthy and so is the camera. Lower picture the radio is at full horizontal.

Wonderful.. just what I wanted to hear.

NIce. At least you can do that. Can't even do that with the XTL5k. You need to hook up to at least one radio to read the serial before you can even open a file. What version RPM is that?

Like the other LMR/Public Safety radios. There are hacks in various forms. It's just find the person or dealer to talk to. Most don't want to deal with grey line stuff so won't bother. The other 1/2 hide in the dark. So if you don't know, you don't know.
