DTR550/650's Cancelled, Meet the DTR700

Postby RFguy » Tue Oct 09, 2018 6:39 pm

The DTR550 and DTR650 radios have been cancelled.

Apparently there is a replacement going to released in a few months, the DTR700. It's "supposed" to be backward compatible with the DTR500/650's.

I found this info on it.

What radios do you own?: XTS/XTL5000, AS+, etc.

Interesting - I wonder what "Phase 2" means for these series.

Glad to see SOMEONE is keeping up with a secure ISM band radio.

The DTR700 and DTR600 are on M's site now. The expected release date from M's factory was around 15DEC2018.

DTR700:

DTR600:

The DTR 550/650 enjoyed a good production run (12 years!). I suspect M is dealing with parts EOL issues in the 550/650 and probably the 410 as well. The DTR 600/700 appears to be the replacement going forward. The CPS has also been updated (R07.00).

I own a fleet of DTR650 radios and a fleet of DLR1060 radios. I pre-ordered a pair of DTR700 radios to start a DTR700 fleet. 8)

Motorola has been updating the main page on their site for the DTR series. I've been checking the page on a daily basis for the DTR700 and DTR600. The DTR700 and DTR600 weren't there a few hours ago and still showed the DTR 410/550 models. Now the page shows only the DTR 700/600 models. The old DTR550 image is still there as of this posting.

Here are some initial first impressions from playing with my DTR700 radios and getting them working with my DTR650 fleet and DLR1060 fleet.

Likes:
  • Best audio of the DTRs (and DLRs) goes to the DTR700 due to AGC in the transmitted audio. It doesn't matter if you talk a few inches away or climb up on it. This is a BIG win in my book and for a lot of people. The older DTRs and the DLRs don't have AGC in the Tx audio. The DLRs will transmit badly distorted audio if you climb up on them. All testing was done with the mic gain at the default (medium) setting. Best audio goes to the DTR700, worst audio goes to the DLRs, and with the older DTR 410/550/650 somewhere in the middle.
  • Slim package design like SL300/SL3000/TLK100.
  • Nice look and feel. Very easy to operate.
  • PTT button is in the best spot for natural feel and operation.
  • Uses color display from XPR7550.
  • Uses keypad from XPR radios.

Dislikes:
  • Antenna connector - small threaded stud instead of an SMA connector.
  • No talkgroup scan feature like DTR550/650.

Programming:
  • Programs like the DLRs.
  • Much easier to program than the older DTRs, less cryptic more intuitive.
  • The Profile ID features first added in the DLRs are nice added features to the DTR700. The 4-digit Profile ID feature makes it insanely easy to set up new DTRs and secure your channels without needing the CPS. New radios can be added to an existing fleet of radios without needing to reprogram all radios in the fleet. Programming Private Groups with the CPS was the only way to do this in the older DTRs. You can still program public and private groups identical to the older DTRs for 100% backward compatiblity if you want to.

Range & RF performance:
  • Appears to be identical to the older DTR550/650 and DLRs, based on testing from several favorite test locations. I haven't had a chance to do any serious range testing yet.
  • DTR700 output power (from FCC grant) = 830 mW (+29.2 dBm)
  • DTR410/550/650 output power (from FCC) = 890 mW (+29.5 dBm)
  • DLR output power (from FCC) = 880mW (+29.4 dBm)

Unknown/TBD:
  • Overall ruggedness of radio = ??? The older DTR550 and DTR650 have a more rugged feel to them. The DTR700 is rugged but feels feather light compared to the older DTRs.
  • Ruggedness and reliability of antenna connector = ??? Too early to tell.
  • Time will tell regarding ruggedness and reliability after years of wear and tear from lots of use and abuse.
