Club Meetings

Regular monthly club meetings are usually held on the fourth Thursday of the month beginning promptly at 7:30 PM and ending around 9:30 PM at the Norwood Civic Center Willett Room located at 165 Nahatan St, Norwood Mass. The Civic Center is Handicapped accessible, and ample free parking is available.

In the event that the fourth Thursday falls on a holiday, which is sometimes the case in November and December, the meetings are moved up a week to the third Thursday of the month. Be sure to check the web site or the club net for firm meeting dates and locations.

Also on occasion, we may need to move our meeting to an alternate location. Be sure to check the web site or the club net for the new location. There are no regular club meetings in July and August.

All regular club meetings are open to the public, and guests are always welcome.

Talk-in to the regular club meetings is available on the W1JLI Club Repeater 147.210 (PL 100.0) up to the start of the meeting.


Norwood Amateur Radio Club 2 Meter Net

The weekly Norwood Amateur Radio Club Net is held on Tuesday evenings beginning at 8:00 PM on the club's W1JLI Memorial 2 Meter Repeater (147.210 PL 100.0). The net contain information about Club activities and other topics of interest. It is held year round and is open to all licensed amateur operators.


VE Testing Sessions

The Norwood Amateur Radio Club has partnered with the Eastern Mass Amateur Radio Group (EMARG) to provide Volunteer Examiner (VE) testing sessions which do not conflict with club meeting dates. EMARG holds their sessions on the third Thursday of each month beginning at 7:30 PM except when our regular Norwood Amateur Radio Club meeting is moved up a week to accomodate holidays. The VE session ends when all applicants have been served. All sessions are held at the Canton EMA EOC Training Room located at 99 Revere St., Canton Mass.

Although many of the Norwood Amateur Radio Club members are also EMARG VE's, there is no affiliation between the two organizations. For information about EMARG testing sessions, you can visit their website at www.emarg.org


Amateur Radio Repeater CTCSS (PL) Operations

For those new to 2 meter FM repeater operation, the W1JLI repeater operates on 147.210 and PL 100.0. What does "PL 100.0" mean? It's a low-frequency sub audible tone used to eliminate extraneous transmissions that can activate a repeater. In addition, some repeaters have the same input/output frequencies because of the large number of active repeaters and a limited number of available frequencies. Imagine the confusion if you transmitted to Repeater A and triggered Repeater B at the same time. To separate the two repeaters a sub-audio tone is used. The tone is called the Continuous Tone-Controlled Squelch System of CTCSS. (Many hams refer to CTCSS as PL - a Motorola trademark that stands for Private Line). When a transmitter is configured for CTCSS or PL, it sends a sub audible tone along with the transmitted voice or other signal. The repeater is programmed to respond only to carriers that send the proper sub audible tone. This effectively locks out signals that don't use the correct CTCSS tone. Repeater operators assign a particular PL tone to their repeater. What this means is that Repeater A responds to one PL tone of frequency while Repeater B responds to a different PL tone frequency thus avoiding the triggering of both repeaters at the same time. Modern VHF and UHF transceivers include the necessary circuitry to generate CTCSS (PL) tones, so if you know the one you need you can simply program it on your rig. A list of current CTCSS (PL) tones in hertz (Hz) is shound below.



Publications such as ARRL Repeater Directory list the CTCSS (PL) tones used by specific repeater systems. The information is also available on the Internet. You can also ask a local ham.
