The W1SYE repeater is back on the air in a reduced capacity experimental mode. It is in a temporary location and is using separate transmit and receive antennas (no duplexer.) The transmit power output is intentionally quite low (670 milliWatts) to avoid clobbering the repeater receiver with RF from the too closely spaced transmit antenna. The transmit antenna is higher than the receive antenna, which is opposite to the conventional way of running separate antennas for a repeater. But it works, and we will keep it on the air in this configuration until it can be returned to service in its regular location later this spring.
Please try out the Mini-Me W1SYE if you have a chance. Don’t expect normal performance, but you might be surprised at how well you can hear a very low power signal from a modest antenna. The receive antenna is quite low, so don’t be too disappointed if the repeater can’t hear you.
<Editor Comment: The audio quality of this new repeater is unbelievably good and it is quite amazing how well 0.7 watts gets out as it is a full S9+ across the bay.>
Last night, NCRC wrapped up a three meeting long Club Build Project of a 40-meter QRP Transceiver “Pixie” kit.
We packaged the inexpensive Chinese QRP kit with sockets for the crystal and final transistor, plus two additional crystals (7.030 and 7.040) to go along with the stock Extra Class-only 7.023 crystal. About two dozen of them were purchased by members.
Over the past three meetings, we set up multiple assembly and test/rework stations. All but four kits worked immediately after assembly. Two had cold solder joints. One had a solder bridge. The only “mystery” turned out to be a LM386 that was on the high-side of its maximum current spec, which caused its power source to collapse. Everyone managed to get the right components into the right locations and there were no missing parts. All of the kits produced from 300 to 400 milliwatts of output power.
Willy, W1LY, and Bob, WB4SON, have been messing around with improvements for the Pixie kit for several months. Most of them have been documented on Bob’s website; you can see them here.
The Club wishes to thank our gracious host, KVH, for assisting us with assembly stations and space for the project, along with all the club mentors that were involved.
What might our next Club Build project be? Something Arduino-ish, perhaps?
In addition to a short business meeting 7 PM Monday April 10 at KVH Manufacturing (75 Enterprise Drive Middletown RI), we will have our final Pixie build/test night. Four assembly stations will be available with mentors to help you complete your Pixie kit. Then we will have at least two test stations that can verify transmit and receive function or help debug your assembled kit.
We hope everyone has enjoyed this project and appreciate KVH for giving us so much support the past three months. Many folks have embarked on more ambitious QRP projects as well.
See you tomorrow!
The NEQP is a great time to check out antenna systems and offers a moderately paced opportunity to work new states and countries. You’ll find a wide variety of participants, from newcomers to experienced contesters, all interested in making contacts with New England stations.
We’re working to make sure that all of the New England counties are active again this year and would appreciate your help. Get on for at least an hour or two and join in on the fun. Please let me know if you can put in any time at all so we can work on activity from the rarest counties. Will you be QRV? Let us know which county you’ll be on from with a message to email@example.com
Oh yes, the NEQP is also lots of fun when mobile. Every time you cross a county line the action starts over again. It’s amazing what a 100w radio and mobile whip can do.
The QSO Party is 20 hours long overall, in two sections with a civilized break for sleep Saturday night. It goes from 4pm Saturday until 1am Sunday, then 9am Sunday until 8pm Sunday. Operate on CW, SSB and digital modes on 80-40-20-15-10 meters. For each QSO you’ll give your callsign, a signal report and your county/state. Top scorers can earn a plaque and everyone who makes 25 QSOs and sends in a log will get a certificate.
Last year we had logs from 179 New England stations and 300 more from around the country and world.

Now that the W1AAD DSTAR repeater is back on the air, there might be some interest in participating in (or listening to) the Raspberry Pi Net which meets on the 1st and 3rd Monday of the Month on Reflector 38C.
You can change the link over to 38C by keying your rig and pressing the “*38C” DTMF keys, or by adding a “REF038CL” to your UR list.
Please be aware that the repeater will automatically relink to Reflector 69C after 25 minutes of inactivity, or you could put it back there when you are done by sending “*69C” or using “REF069CL” from your UR list.
There is also a rather active Facebook Group called “Raspberry Pi Amateur Radio” with almost 3,000 users. https://www.facebook.com/groups/251260325054240/
