Field Day 2017 – Please Sign Up for Dinner Sat June 24

Field Day is rapidly approaching.  It will be June 23-Jun 25.
You can find out more details about Field Day by going to this website link:
PLEASE take a moment to sign up for dinner.  Ed needs to get an estimate of those attending so he can purchase enough food.  As a reminder, Saturday Dinner is open to all club members and their families, and is free of charge.  Just let Ed know the total number coming.  You can see that there is a form on the website given above that allows you to fill in the dinner reservation electronically.  Again, that website is  http://w1sye.org/?page_id=3287

NCRC Meeting Monday May 8 @ 7 PM KVH

Hard to believe it is meeting time again, but we will get together at 7:00 PM at KVH 75 Enterprise Drive, Middletown RI.

We will start our Field Day planning and have a short business meeting.
After the business meeting, Paul K1YBE, will have a demonstration of the Pixie transmit signal and how the standard filter does not attenuate the 2nd harmonic enough to produce a pure sine wave.
See you tomorrow night!

Don’t forget the Wed 80 Meter Net

NCRC, since last Fall, has been running a HF Net on 3.900 MHz on Wednesday nights at 7:30 PM local time.  Conditions have been excellent since the change to Daylight Saving Time, and its been fun hearing the participation increase each week.  Tonight, for example, we had 15 stations from RI, NH, MA and CT check in, almost all with excellent armchair signals.  Rich, KC1ARO checked in portable from his location in the White Mountains of NH using a 80 meter “Hamstick” on his car.

The other thing that is interesting is it is an opportunity to dust off some of the wonderful tube radios that we all have.  It is wonderful to hear a rig like the Drake TR4 or Swan 500 on the air with their sweet sounding audio.

So don’t forget, Wednesday nights, 3.900 MHz at 7:30 PM local time.  Hope to hear you soon!

PS:  check-ins for May 3 included the following:  KC1ARO, K1YBE, N1PSX, K1ECU, W1LY, WA1ABI, KC1HEP, WX1X, WB1CTP, W1DEC, AA1XQ, N1ENG, W1VAK, K1GHC, WB4SON

W1SYE Repeater Back on-air in Limited Capacity

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.>

Pixie Project Completed Last Night

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?
