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.

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.

John,

Thanks for allowing this and thanks to KU7M for doing live play. 

Is it possible to post an approximate schedule for the talks?

Will the be recorded and available on youtube afterward?

Thanks in advance.

Live Streaming of Microhams Digital Conference 2018

 

http://www.microhams.com/2018/03/22/mhdc-2018-live-stream/

Tomorrow, Saturday, 3/24/2018 is the MHDC-2018 – this conference sold out immediately last January and many people who wanted to attend were unable to get tickets.

KU7M – Kenny Richards, will be live streaming the event.  All times are US Pacific Daylight Savings Time (UTC-7).  Use the above link to find the live stream on YouTube.

Current Speaker List :

Joe Taylor– We are pleased to announce that Professor Joe Taylor, K1JT will be speaking at this year’s conference.  Joe is Professor Emeritus of Physics at Princeton, Nobel Laureate and author of the JT digital modes.

 

Bryan Hoyer– One of the conference’s past presenters, Bryan Hoyer K7UDR of NW Digital Radio  , will be giving a talk on “The APRS of Things” and demonstrating their newest products.

 

John Langner–  WB2OSZ, the author of the Direwolf sound card TNC will be speaking.

 

Ken Koster – N7IPB will present using SvxLink to connect a network of 220 repeaters in the Pacific Northwest. SvxLink runs on a linux computer and provides a custom dual radio interface for FM voice repeater control and linking over the Internet. Ken will provide an overview of how a mix of repeaters are connected via RFLinks and the Internet, as well as the real-time status information available via the web.

 

Alex Schwarz– VE7DXW the developer of the RF-Seismograph and MDSR will present the results of the RF-Noise monitoring experiment during the solar eclipse and the turbulent solar activity (including the strongest X-Ray flare in 30 years) that followed.

 

Guus van Dooren– PE1PLM Entrepreneur and creator of DVMEGA.  Guus will discuss the latest D-Star developments.

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: Another funny project with the ThumbDV :-)

 

Hi John,

The addition of an AMBE3003 will be very very nice! Then you can select more reflectors you want to hear.
Website can be down sometimes because I am still developing and learning JavaScript. 

The software is not for public because it is still under heavy development. 

Greets,

Re: Another funny project with the ThumbDV :-)

 

David,

Nice -- working here.  With an XC-3006 someone could build this into a multi-stream page :)

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.

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.
