Harry W2HRY and myself replaced our 2 meter DR1X repeater with a new DR2X model. All went well and settings are the same for the moment. We will likely move from a CTCSS Tone Squelch to a DCS (Digital Coded Squelch) system in a couple of months.
DCS is a newer and better system from a performance standpoint. It will hopefully eliminate squelch hang and noise.
This is a Map of System Fusion repeaters I copied from repeaterbook.com. It gives an idea of density and locations of System Fusion activity in the US. In some places, like Phiily/NJ area, too many to individually show at this zoom level, so it just looks blurry blue. Click on the Map for a larger version.
I have schedule another Fusion net on the W2XRX repeater – here is the info:
Tuesday Mar 28 at 8PM, there will be a Fusion net on the 145.29 W2XRX repeater (Canadice, NY). The mode will be digital narrow DN. It will be on Wires-X room #21704. The purpose will be to discuss Fusion news, equipment, Wires-X, tips, etc. Check-ins are encouraged from all CNY/WNY Fusion stations. Initially we would follow-on with a net every 4th Tuesday of the month. More frequent nets could be added if enough interest.
Seeing the predicted coverage of the 440 repeater, I decided to try our 2 meter machine. A few variables I took the default, but this looks pretty close based on my living at the fringe area. It might be slightly better than shown here, but this is not bad. Definitely can see the problems going east and south, with higher ground in both directions.
XARC will be hosting 2-meter Nets on the first and fourth Thursdays of each month starting at 8:30PM. The net will use the club’s Yaesu – Fusion repeater set to analog mode so that all can participate. The repeater (callsign W2XRX) frequency is 145.290Mhz with a PL tone of 110.9. All check-ins are welcome.
There was a kind of semi-bungled release of the long-awaited software updates from Yaesu this past week (long story). This includes updated Wires-X node software, and new software for the DR1-X repeaters to allow connection to a Wires-X device.
Since we have no internet connection at the repeater site, the first option is more interesting to us. I have a Wires-X device, a PC, and a FTM-400DR at my home QTH, that up until now, has only had limited functionality in analog FM. With this new software release, I can now use my node to point to our W2XRX repeater and have full digital capabilities. It can also work in analog FM, but setting the mode on a Wires-X node is not automatic, and has reduced functionality. So I will likely concentrate on digital.
I’m starting to see what Yaesu has been trying to do. Frankly, now that I see it, they probably would have been better off just forgetting about making it analog compatible so they could have more resources getting Fusion perfected. But it is finally getting there. I have a FT1XD handheld on order, and I’m selling my old HT.
Here are a couple of videos that might help with an understanding of Wires-X. They aren’t great, but are a start. For those of you who have asked “why would I want a Fusion radio?”, these help show some of their capabilities.
A couple of points – you don’t need to have your own Wires-X node to use one. Best case scenario is that the Fusion repeaters in the area would be connected (directly or via a node like mine). You can then connect as shown in these two videos (with an HT or mobile).
The PC screen in the first video is the PC running the node software that controls the node. It provides connection to the internet and controls the node radio.
There will hopefully be more updates in the coming weeks. Maybe some more videos – if I find anything interesting I will pass along.
I went down/up to the repeater site today, and made the following changes:
Added a RF Concepts RFC-2-317 amplifier to the transmitter
Added an Advanced Receiver Research P144VDG Receiver Preamp
Added a Wacom Bandpass filter in the receive path
Added a Wacom Bandpass filter to the transmit path
Added a 12 VDC power supply for the amps
The bandpass filters were previously installed at the Xerox Tower site.
Mike Ishler KE2LU donated the RF Concepts amplifier. Thanks Mike!
I had no serious test equipment, but everything seemed to be working.
The repeater is set to 20 watts, and according to my MFJ VHF Wattmeter/SWR meter, the amplifier is putting out around 80 watts. The amp is not designed for repeater duty, but we are only running it about half rated power. It has temperature protection, but I want to get a fan on it.
Initial reports are good. I’ve had a few QSOs, including one with Harry W2HRY, just using an HT in my shack at home, about 39 miles from the repeater. On my 2 meter mobile in my shack, it went from 1/2 scale on the s-meter to one notch from full scale.
Mike W2HYP had no trouble using an HT from the U of R just after I made the changes.
The addition of the preamp changed the squelch action, so I did my best picking the right level. The squelch has always been questionable, so additional tweaking may be necessary, including an internal “threshold” adjustment.
If you get a chance, see how it is working for you, especially if you had some problem areas where it was marginal. If things seem to be good, Fred Miller WO2P has agreed to help package things up in the repeater cabinet.
