W6CX-DV repeater upgrade
|
The W6CX Digital Voice repeater (145.0 +2.5 mHz) that repeats D-Star, DMR and C4FM/Fusion was upgraded yesterday. Trevor and I spent about 4 hours at the South Peak site.
The key changes were: * DV software was changed from Pi-Star to the new WPSD by W0CHP. While Pi-Star was wonderful and many people still run it on their Pi-based digital voice hotspots, Pi-Star is no longer being maintained. Fortunately, Chip W0CHP has taken over the Pi-Star system, made major upgrades to it, renamed it WPSD and is keeping it up to date. * Updated the firmware in the MultiMode Digital Voice Modem -- we now have the latest with various enhancements including support for the new M17 open source digital voice mode. The new WPSD Dashboard does look a little different from our previous Pi-Star dashboard. You can check it out at . Any feedback or comments on these changes are welcome. Jim - K6JM |

The new software got my attention this morning; I did a refresher on the browser. A a very casual operator, I have not been keeping up with the changes in the repeater/digital world. Job well done by you and Trevor. Lately with my mag mount on a filing cabinet and 15 watts the repeater hears me but I don¡¯t hear it, no one to blame but myself. Thanks to you and Trevor for all your work and know how keeping the repeater in operation. 73, John kf6wsk On Dec 1, 2023, at 9:02?AM, Jim - K6JM via groups.io <jmm@...> wrote: |
¿ªÔÆÌåÓýYou are the first to ask about P25.? ? A multimode repeater normally waits for an incoming signal, then checks, one mode at a time, to see if it¡¯s a mode that is enabled on that repeater.? Of course, this happens pretty fast, so having several modes enabled should not materially affect how quickly a mode will be recognized.? But I guess, the more nodes it has to check will very slightly add to it reacting to the first transmission. ? After that, it locks onto that mode so that back and forth QSOs will keep the repeater in that mode.? After a given time of hearing nothing incoming, the repeater resumes checking for all enabled modes again.? All this is intended to keep another mode from high-jacking an ongoing QSO.? ? But a friend of mine, Don WB5EKU, has put up a multi-mode repeater in Los Angeles.? Wide coverage.? He has enabled D-Star, DMR, YSF, P25, M17 and NXDN.? Apparently all is working fine.? You can read about it at and you can click on the Dashboard link at the top to see recent traffic there. ? Let¡¯s discuss this more via email off-list.? Just send me a direct email to jim@... .? We could try some experiments. ? ??? Jim ¨C K6JM ? ? From: [email protected] <[email protected]> On Behalf Of S C - KJ6FNN

¿ªÔÆÌåÓýShon, ? K6PUW is on Oat Mountain, north of Los Angeles.? But they do have some P25 users down there. ? I don¡¯t have a P25 radio.? I was thinking we could coordinate a test where I would enable P25 for a while and you could see if your P25 radio could get into the W6CX-DV repeater.? I know there are some ¡°reflectors¡± set up for P25 and ideally you could link in and have a P25 QSO with someone on the network.? Also, if you know local hams with P25 radios, perhaps you could also have a local RF QSO.? ? We have found some DV modes are very sensitive to the transmitted signal¡¯s deviation.? As far as I know, DMR is the most sensitive, which is why Trevor and I spent most of our time testing our multimode repeater using DMR.? The thinking is ¨C if a repeater can deal with DMR, all other digital voice modes will also work without adjustment.? ? That proved to be true of Yaesu¡¯s YSF/C4FM mode. ?Without any testing, I just remotely enabled YSF and the repeater was able to receive and transmit that mode.? I suspect the same would be true of P25, but of course that would need to be tested. ? Let me know if/when you¡¯d like to test P25 on W6CX-DV.? Just email me directly at jim@... .? ? ?????? Jim ?

Congrats! I'm sure we're one of the only repeaters in the world to

enable M17. Can someone write this up for the January newsletter? I'm cc'ing Matthew as a heads up. 73, Grant K6CBK On Thu, Dec 7, 2023 at 12:06?PM S C - KJ6FNN <bredalrv@...> wrote:

Shon,
I am away from home, back late Wednesday.
Basically I will soon enable the P25 mode for a while so you can test. I will send you an email when I do.
Do you know another P25 user who is within RF range of W6CX digital voice.
If yes,? that would tell us if the repeater's deviation will work on P25.
Could you also do me a favor and go to ?? Check out the brief info about P25.? Also check their Dashboard.? At bottom left it should show whether it is "linked" somewhere.?
What I want to do is learn is if I need to change P25 settings to allow you to have QSOs over the network, for example by linking to a P25 "reflector".

Hi, Jim. Thank you. I don't know another P25 User but I was going to record the P25 Transmission on both my?Unication G5 Voice Pager Receiver and?Uniden SDS200 Digital Police Scanner. both can decode?P25 Phase 1 and Phase 2
I looked at?? and only found?WPSD Digital Voice Dashboard for K6PUW But I did find another Ham P25 Repeaters Southern California's Premier Repeater System??there is based on a Motorola MTR2000 analog with a Repeater Builder STM-32 MMDVM card installed in the expansion slot. there card runs Pi-Star. They? have a P25 Reflector List ? Also, it looks like?Salinas Valley Repeater Group has mix mode p25 Repeaters? w6dxw.com/index.php?id=22? Shon KJ6FNN 73 Salinas Valley Repeater Group? |

Good idea, but the M17 mode has not really been tested yet. Given that many of us are just waiting for commercially-available radios that can do M17, testing must be done with DIY M17 radios. I am setting up an M17 radio using a Pi running a program called M17Client. The Pi has an MMDVM modem plugged into it, and the modem is connected to an analog FM radio. When audio levels are correctly set, this setup will transmit and receive correct M17 signals. I had some setbacks due to the analog radio I chose to test with, but I hope to get a valid M17 test of our W6CX-DV repeater soon. Once, that is proven to be working, I will write up something for the MDARC Courier. Jim - K6JM -----Original Message-----
