• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

It’s not terrible, but it does have a pretty major learning curve. The way scan works is the biggest issue for me personally as well as everyone I’ve demoed these to.

As far as 900 ham as stated above it works fine but if you are going to be using it a lot I would buy a dedicated 900 antenna as the provided V/U/7-8 isn’t technically rated for it.
It just has trouble scanning mixed mode? Does it scan a bank of all analog ok?
I was planning on getting the 900mhz antenna. Do you know what kind of connector these radios have? Can you use other brands?

Thanks for the info!

scans analog just fine and fast. Also scans analog and P25 both conventional/trunked mixed together just fine.
The Antenna is a sma male (antenna side) to female sma on the radio side

Scan seems very unstable with the current version of firmware. Has anybody been able to get "In Zone" scanning to work with a zone of all DMR channels? I get a "Please Wait..." message but the radio never starts scanning. I am also getting "system error" messages with "talkgroup" and "standard" scanning configurations. Love the radio but the scan functionality or lack there of is a huge issue.

How are you all programming your scan button? The CPS seems to strap a single scan group to a function button.

I have gotten a single zone to scanall dmr, but not by in-zone. I set it up as standard scan and added dmr channels from that zone and other zones. I have a couple buttons dedicated to scan lists, but also found out the last channel in your zone is usually labeled as the scan list... example... say I have dmr zone 1 with 20 dmr channels. I set up a scan list in that zone as standard scan, label it DMR scan and add say 5 channels with the scan list editable. Channel 21 slot (for lack of better words) will list as "DMR SCAN" and enable/ toggle your scan list.

AND YES, SCAN sucks on this radio thus far, I shouldn't have to use all my buttons to enable different scan lists. The last channel scan set-up works as described above, but it's not as easy as one scan button and the scan list is assigned to each zone like say MOTO...

Hope that helps..

In-Zone scan is the best way to do what you are trying to do (separate scan list for each zone) but as you know there is the bug with trying to scan DMR and you are limited to what's in that zone. You are also limited to 72 zones if you do that, which sounds like a lot but when building a large regional codeplug fills up fast. The issues with the way scan works are what makes it a "meh" radio in my opinion. I think it has potential but I don't see Tait changing the way it works.

Completely agree, I really like the radio. The audio is fantastic but the scan implementation makes it a non-starter for my agency unfortunately.

We have some of the TP9900 radios at work, I am pretty impressed overall, multimode & multiband is great.
Most of the options are enabled on our test radios too, except for encryption (not even basic digital encryption is enabled, odd..)
So far have just been testing these in DMR & P25 conventional modes.
Yes it is a slight annoyance that you cannot have DMR & P25 channels in the same zone.
Also, if using these radios to just RX scan P25 trunking systems using the P25 conventional mode, it appears you are not able to program the radio to selectively RX individual talkgroups. I have tried various settings, and it if set to Selective under the Basic P25 Settings page, the radio appears to just RX the TG listed in the Talkgroup column on the Channel page. Selecting another TG via the Menu has no affect on this behavior. I am guessing this will only work correctly when the radio is set up for P25 Trunking mode, which I cannot do of course without a system key. Anyway, the audio sounds very good, and is nice to have a commercial portable to play with that covers the 2m & 70cm bands !
Pity I could never afford to buy one for personal use.....
