Re: Live Streaming of Microhams Digital Conference 2018
Jack,
Your welcome, but I am one of a small team making this happen. Dennis-K7DEN is doing most of the heavy lifting and David-W7CF is our inside man at MSFT. The schedule is will be posted tonight, a last minute change had to be worked out due to one of the speakers being sick. Look for it on the MicroHAM site in a couple hours. The entire stream will be saved and made available via Youtube. We try to also break out the individual talks, clean them up, so they can be reposted separately. But that depends on available time from the local video editor. 73, Kenny, KU7M

Re: Live Streaming of Microhams Digital Conference 2018
As I said, I am only passing along information. Past history shows that talks may be moved around -- I got a note from N7IPB that he will be unable to speak, so there will probably be a substitute.

Unfortunately that cold that has been going around still has me firmly in it's grip so I won't be speaking. Instead I'll be sitting at home watching the stream and drinking warm liquids.

DCS Reflectors ircDDB Compass UDRC
W0NV
Hellos group, I am running ircDDB on a Compass based R-Pi attached to a UDRC. The hot spot works great on REF reflectors. Recently I wanted to connect to DCS 054A (The Carolina Link) however I cannot. DCS is enabled. I think I need to load DCS_Hosts.txt but I don't know where to get this file; nor do I know where to put it. Thanks in advance for any help. De K4RNV, Niles

Re: Motorola Quantar & digital modes
Mike Moore
I saw a post in the repeater builder group about problems using the Quantar as a digital repeater. I can't find the link now but will repeat the clipped test of the post. I can't confirm this problem personally but there is help out there. Sorry that I don't have the contact information from the post. 73, KC2NM POST: Hooking up MMDVM (I used a ZUMradio Pi Hat v.0.9)to a Quantar was only partially successful. I have a decent amount of experience with Quantars as well- I run a system which has 7 Quantars which are linked in P25 and analog running mixed mode. I've also done board level repairs. It boils down to this: The Quantar works great in P25 using MMDVM (no big surprise there). As for DMR, it will transmit DMR no problem, but the receive just WILL NOT WORK. The furthest it could get was to see the downlink activation request from receive and would key up transmit, but it only intermittently recognizes sync (watching the MMDVM debug output). I tried it only using P25 and DMR, nothing else. To get it to this point, I ended up having to tap into the station control board at the most raw audio points I could find that low pass filters were not in the way. The wireline and MRTI interfaces didn't work at all for me. I would imagine the other non-TDMA protocols would probably work. I was really perplexed as to why it would transmit DMR but not receive it. After doing some analysis with my service monitor and O-scope, it looks like the issue is the phase delay of the RX audio varies wildly as you step up through the audio frequencies. This is not the case with the transmit side which works nicely. Keep in mind that all the audio in a Quantar (even analog) is digitized, so you never get to see what would be raw, analog discriminator audio. As a comparison, I looked at the receive side of a CDM mobile radio which is known to work well with MMDVM DMR and found the phase delay was very consistent, unlike the Quantar receive. At one point, I had the CDM mobile doing receive and the Quantar transmitting....what a frankenstein. I had high hopes the Quantar would work with MMDVM because they are EXCELLENT repeaters, but this thing was developed over a couple decades ago and this TDMA wasn't considered in the design process. I hope that clears this question up.

Re: Motorola Quantar & digital modes
Steve Stroh
To finish John's thought, all digital voice radios that I've ever heard of (D-Star, DMR, P25, even System Fusion) are backwards compatible with FM. With the modification that John describes, you run the radio in FM mode. It's ideal if the radio is flexible about the channel size. For example, D-Star uses a 6.25 kHz channel rather than the (traditional to FM operation) 25 KHz channels, and the more common these days 12.5 kHz channel.

Re: Motorola Quantar & digital modes
Jim, You don't need an AMBE chip (eg. ThumbDV) at the repeater. Most digital modes require a modem that is connected to the discriminator and modulator (flat audio, no pre/de-emphasis) and appropriate software to handle the protocol. The UDRC II was designed to provide the hardware to support software defined modems and PTT -- see https://nw-digital-radio.groups.io/g/udrc/wiki/UDRC%E2%84%A2-For-Simplex-Hotspots-and-Converted-Analog-Repeaters

Motorola Quantar & digital modes
jim lang <jimlang@...>
Does anyone have experience / knowledge of connecting say a Thumb DV or anything digital to a Quantar? I have recently obtained a UHF Quantar, and was wondering if it is humanly possible to run it both analog (FM) and in digital modes…I know it’s already P25 capable, but thinking more along the lines of D-Star, Fusion, etc., etc. (whatever the flavor of the month might be!). Basically, whatever comes in (i.e., analog, Fusion, D-star) goes out.
Thanks in advance,
Jim / kd9gy

Hi All,
You can listen to the REF030 C with your webbrowser. All DSTAR is voice transcoded by my ThumbDV. Will let it run for a few days until I need my ThumbDV again. http://dashboard.pa7lim.nl:3000/

Re: Help NW Digital Radio with your view on GPS for new product
Steve KB9MWR <kb9mwr@...>
Can't say I am interested in that. I would be interested in say a 5 watt radio capable of SSB for 70cm. Something like the friendcom units, except capable of SSB. I could of swore David Rowe had plans for something like that, but really haven't been paying attention.
The way I see it, one can only do so much with a Raspberry Pi and sound card without more capable radios.

Help NW Digital Radio with your view on GPS for new product
NW Digital Radio is seeking input for the next Raspberry Pi based Amateur Radio digital station platform. The new Raspberry Pi HAT will contain a CODEC (sound card) based on the successful UDRC II and will include two amateur radio packet standard mini DIN-6 ports allowing one or two radios to be connected with PTT and SQL detect and support programs/protocols such as: Direwolf - providing multi-speed packet radio modems (2 channels) [APRS, RMS, Xastir, URONODE, ...] wsjt-x - K1JT family of digital modes including FT8 fldigi/flrig/... - digital modes and more This will be an integrated package, in a custom case, with available pre-built images requiring minimum configuration. Please participate in the survey here, and give your opinion on GPS integration. It is only one multiple choice question and should only take a minute of your time. Take the Survey Thank you. Feel free to forward this email to appropriate individuals and mailing lists. John D. Hays Edmonds, WA K7VE

Re: Compass build - Unable to locate package ircddbgateway
You need compass if using the UDRC, for ircddbgateway/ircddbgatewayd you can use Debian/Raspbian There are .deb files under http://archive.compasslinux.org/pool/main/i/ircddbgateway/ (you can add archive.compasslinux.org as a repository or pull the debs, including dependencies).
