The Topeka 146.805 repeater is digital only using an MMDVM with Yaesu System Fusion (YSF) and DMR modes enabled. The YSF Mode is linked to the US-Kansas3120 YSF Reflector. The DMR mode is connected to KS-DMR. KS-DMR talkgroups are available by PTT activation.
- Antenna: DB-224-E at 510 feet
- Andrew AL7-50A transmission line.
- Output: 25 watts
- RF Deck: Kenwood TKR-750
- Raspberry Pi 2 B
- N3XCC v2 STM32
- Pi-Star software
The mode priority setup is:
- System Fusion
- Tune your radio to 146.805 with – offset
- Use DG-ID TX:00 and RX:00 (radios with old firmware should have Digital Squelch Code set to OFF)
- If you are going to use AMS mode on your radio, you will want to also program a TSQ (Tone Squelch) to 162.2 just for keeping your radio from inadvertently switching to FM mode (since there is no FM on this repeater).
That is the extent of the setup required to access the YSF mode. Additionally, here are some important points of interest:
- This repeater is normally networked to the “US-Kansas3120” YSF Reflector.
- You can link to other reflectors by entering WiRES-X mode on your radio and selecting another reflector.
- Please move it back to US-Kansas3120 when you are finished with your contact.
- You don’t need to use WiRES-X mode if you plan to stay on Kansas3120.
- YSFReflectors are an open-source alternative to the official Yaesu WiRES-X network. You cannot access official WiRES-X nodes or rooms via this repeater.
- The US-Kansas3120 YSF Reflector is bridged to KS-DMR Group 3120. You must use DN mode to communicate with DMR users across the bridge. VW mode will not work. If you want your callsign to show up on DMR radios you will need to register your callsign with radioid.net.
- Your codeplug will need one “channel” programmed for every talkgroup you intend to use. Your radio will have to be programmed with your unique DMR ID (obtained from the RadioID.net website)
- Each channel will have to be configured with:
- RX Freq: 146.805
- TX Freq: 146.205
- Color Code: 1
- The time slot you want to use
- The group ID you’d like to use from the list below/
KS-DMR Repeater TGID tableTable showing the available talk group ID's on repeaters connected to the primary system.
|Voice for Linked Group||1||9|
|Subscriber to Subscriber calls (brief)||1||(Private radio ID)|
There are no static talkgroups assigned to either time slot. You must first activate a talkgroup by keying PTT for two seconds. Upon unkey, the talkgroup will be available for use.
- Example: To use TS2:3120, key up on that channel for two seconds then unkey. Now you can key up and communicate via 3120. (Yes, you essentially have to “kerchunk” one time to activate it.)
To access any of the available linked groups:
- Select the channel programmed with TS1:TG9.
- Go into your contact list, select the talkgroup (from the list below) you wish to link to and key PTT for two seconds with the desired linked group selected. When you unkey the link will be activated.
- When your radio display reverts back to S1:G9 you may begin talking.
- Note: The linked group ID’s are to be used for in-band signalling to trigger link activation, not to talk on. All voice traffic for linked groups happens on TS1:TG9.
- Please don’t do this to “lurk” on a group.
- Linked groups remain active for 15 minutes after the last local transmission, and only one linked group is available at a time.
- Please do not transmit voice on any TGID not listed above.

- The DMR mode on this repeater is offered as a convenience to travelers and visitors with VHF-only gear to use while in the area. Regular local users should use Topeka 443.625 for DMR calls whenever possible.
