Come help Valley Wide REACT support BSU for the Homecoming Parade on Saturday afternoon. This event involves a hard closure of University between Broadway and Capitol. Contact Russ, N7SMA or AJ, K6LOR for details.
Contact Russ, N7SMA or AJ, K6LOR for details – this is an evening event in the downtown Boise area requiring traffic control.
The first event of this upcoming week is Monday night!
Contact Russ, N7SMA, AJ, K6LOR, Tim, WA7TJB or Wade, KD7VNS ASAP if you can help!
This event starts and ends at Hyde Park Cycle Sports on 13th St and Eastman.
Start time is around 7:30 –
Communications will be on the 146.680 repeater with 146.58 simplex as a secondary
There are major intersections that will require clearing, along with possibility of a rolling road block and/or escort. Lots of variables due to the nature of the event, time of day, and the involvement of motor vehicles.

The Twilight Mardi Gras Ride kicks off the week’s riding events. This route has something for everyone – beautiful residences along Harrison and Warm Springs, the Greenbelt, Julia Davis Park, and a great ride up Capital Blvd. on our way back to Hyde Park. This leisurely ride is designed for all ages, abilities, and types of bicycles. Be sure to bring your helmet and wear your Mardi Gras best and lots of lights. The Mardi Gras Ride is a great way to get warmed up for the rest of the week’s riding events, meet other cyclists in the community, and enjoy a great evening out on your bicycle. Make sure and get there a little early to check out all of the great gear that Jim Powers has to offer to the cycling community at Hyde Park Cycle Sports. This will be a great opportunity to check out the latest in lighting technology and see how other commuters stay visible at night.

Meet us at Casa Mexico in Boise tonight at 1900 MST (7 pm local time) for our team General Membership Meeting. Casa Mexico is located in the same strip mall as Harbor Freight, Radio Shack and the Buffalo Club on Fairview Ave, just east of Five Mile Rd.
Hope to see you there!
Looks like the 10V Regulator Card in the VHF repeater was swapped while on the site last weekend.
As a result, I had to modify it to match up with the
“repeater station” circuit needed to prevent the repeater from “repeating” on its own without an external controller (like it was this morning).
Also found sucked out (improperly installed) PL-259 fittings on 4 of the 8 connectors on the interconnection cables.
I also had distorted audio when connected to the controller and when connected through the GE stock repeater card. The NHRC7 controller was fed off of the discriminator audio which would have come directly off of the system monitoring board. Moving the RX Audio over to the SPEAKER HI terminal on the back of the system control shelf resolved the audio issues.
There are still some hum issues on received audio that do not show up on controller generated audio (such as after COR opens during hang time, courtesy tone and CWID). Monitoring from a scanner with tone decode, it appears the GE board, which decodes the 100.0 hz PL tone, does not seem to filter out the subaudible tone. Subsequently, the hum on the transmitted audio appears to possibly be retransmitted CTCSS tones from subscriber radios keying in to the receiver.
The 9914 Nm-Nm jumper appears to have been the only good coax jumper amongst the lot taken with the repeater off of the mountain. I cut it in half and soldered on new PL259 connectors. The output ports for the RX and TX on the Mastr 2 are SO239 (UHF) connectors. The input ports to the duplexer are Nf connectors. By putting PL259s on the radio site and using the existing Nm connectors on the duplexer side, I’ve been able to remove 3 extra adaptors previously in use.
Also looked in to a few options for continuing to use the CSI TP3200 Community Tone Panel for tone encode and decode.
On 2/7/09, Russ, N7SMA & AJ, K6LOR met up to realign the 147.080+ Mastr II VHF repeater that was previously up on Wilderness Ridge. We are happy to report that, after some interesting “tail chasing”, the VHF repeater now sits at a very reasonable .18 uV sensitivity as measured by a calibrated HP spectrum analyzer and is spot on frequency, plus or minus a few hertz, with 26 watts out at the P/A. The remaining desense issues are in three distinct locations that must be resolved:
- Repeater to Duplexer Interconnection Cables
- Receiver to Duplexer
- Transmitter to Isolator
- Isolator to Duplexer
- Duplexer to Antenna Cable
In order to trace down the desense, the interconnection cables are the first to be replaced as they’re already a mismatch of cabling:
The overall consensus of the repeater building community is that anything other than Heliax-type cable will likely result in some form of leakage, contributing to desense.
Thank you to REACT Life Member Tom Jenkins, N7VOI for directly supporting the safety and security of the SOWWGs Wednesday, February 4th during the downtown events in Boise. Another example of REACT’s continued commitment to providing practical, useful public service while using our communications skills to further increase our value as volunteers!
