The Radios
Wow... it has been probably a year since I updated the list. I bet I added 40-50 to The Radios page.

Ham in a Can
I post a lot about Alexa and other similar devices, but I had not thought about adding one to the ham shack.

Radioddity Baofeng RD-5R: DMR HT
Based on the UV-5R form factor, Radioddity is releasing a new DMR HT... the RD-5R:
As the first Radioddity-Baofeng co-produced DMR, RD-5R is featured with solid quality and affordable price. The FM radio function, LED flashlight and built in VFO mode make it stands out from other DMRs.Fingers crossed that this will be a better radio than the DM-5R. Projected price is approximately $70 USD. In the comments, they note that the "RD-5R share pretty much the same CPS with GD-77 and hopefully this will make it a lot easier" to program and thus it will have all the GD-77 DMR functionality.
Sticked with classical design of the 5R family, this time RD-5R is a true dual band dual time slot DMR.

DCRainmaker Pro Cycling Ride Along
DCRainmaker is my go to resource for information on running watches and other, similar tech. He got to do a ride along with a pro cycling team in their support car. He talks about some of the radio problems and what looks like an Alinco DR-635 makes an appearance.

Baofeng BF-T1 (BF-9100) on Facebook
"1. When using the amateur radio band of 70cm, then the 2nd harmonic is approximately -30dBc (dB relative to carrier). No detectable 3rd harmonic.
2. These radios appear as though they can be used on the 2m amateur radio band, by going into the programming system.
HOWEVER! When transmitting on 2m. The fundamental is very low and the 2nd and 3rd harmonics are GREATER than the fundamental. Therefore I conclude that these radios must not be used on frequencies, different to those stated by the manufacturer."
BF-T1 measurements via SDR dongle (so take them for what they are worth):
"I have received and programmed the Baofeng T1 but i may have some problems with it. While it works correctly in the UHF it outputs only very low power in VHF."I agree with Jim:
"It isn't designed to TX on VHF. You should only program VHF frequencies for RX only. For example NOAA weather radio reception."You can pick one up for cheap on Amazon:

Baojie BJ-218 Software
In the comments on the original Baojie BJ-218 2M/440 Mini Mobile post, some folks were looking the programming software. Someone posted the link to the Baojie downloads page that includes the software.
It also looks like you can use CHIRP:
Yes, the BJ-218 works with the Luiton LT-725UV CHIRP driver as well as the factory software. I have one of each, an LT-725UV and a BJ-218, factory software and files are interchangeable, and I was able to write my LT-725UV CHIRP .img file into the BJ-218 without issue. My only question is when will the LT-725UV driver go from 90% to 100% and leave the Beta stage?

Baofeng BF-T1 (BF-9100)
Some interesting stuff about the Baofeng BF-T1 that Ivan Hazelton shared* on the original BF-T1 post:
Good news! With the programming cable you can program this little rig with 20 channels 400-520MHz and 130-174MHz. Now be aware that the antenna is ... sub-optimal for the 130-174MHz so a suitable replacement will need to be MacGyvered. It'll be great to have a little, >$20, 4oz, disposable, dual band rig. It goes by another name BF-9100A, and the software to program it can be found here or direct linked here (.rar file). The cable does use a fake PL-2303 serial chip, so you'll also need the drivers off the same page, or direct linked here (.rar file).
Direct link to BF-9100A/BF-T1 Manual (.doc).Also, it has CHIRP support.
*I've done some editing so the links work.
