Weekly 2m Open Net
Come and join us on our weekly 2m Open Club Net. An amateur radio “net” is where a group of radio operators congregate upon an agreed frequency✝ at a specific day and time to have an informal, friendly conversation.
Frequency: See table, below.
Reach: Hampshire and Isle of Wight; possibly West Sussex and Dorset.
Fort Purbrook Amateur Radio Club holds our open club net on the 2m band (FM) for all club members and all licenced users in the area (passers-by, non-club members, etc). Shortwave Listeners (SWLs) & pre-licensed amateurs are welcome to listen in.
✝ “frequency” if using an RF means of radio contact or, if using a digital means, an agreed channel access as defined by the technology (e.g. Echolink, Peanut, Wires-X Rooms, D-Star Reflectors, DMR Talk Groups, etc).
Trouble Locating Us?🔍
If you don’t hear us on GB3CW, try us on the GB3SH (2m) or GB3SU (70cm) repeaters. If all repeaters have failed us (bad QRM etc), try listening around 145.275MHz simplex for us.

About our 2m Net
We open the net with our Net Controller TX’ing from Southsea, usually calling on the Fareham repeater GB3CW. If, during the net, we experience unfavourable weather or propagation conditions, we may QSY to repeater GB3SH or GB3SU (70cm). Prepare all these repeaters (details below), storing their details into your transceiver’s memory.
There’s no set topic—any subject (within amateur radio etiquette) is welcomed.
🎙️ Come join us this Thursday evening; we’d like to chat with you!
Summary and Repeater Information
| Club Net call-sign: | G3CNO/A | |
| Day/Time: | Thursdays 1930 (Local Time) for around an hour. | |
| Frequency & Mode: | GB3CW | We usually begin on the Fareham GB3CW repeater. (FM, 145.6125MHz, -600KHz, Analogue Voice with CTCSS: 71.9Hz). |
| GB3SH | We may QSY to Southampton GB3SH repeater depending on conditions. (FM, 145.6625MHz, -600KHz, Analogue voice with CTCSS 71.9Hz). | |
| GB3SU | We may QSY to Southampton GB3SU repeater depending on conditions (NB: this is a 70cm repeater). (FM, 433.200MHz, +1.6MHz, Analogue voice with CTCSS 71.9Hz). | |
| 145.275 MHz simplex | If we cannot use the repeaters (eg QRM) come find us somewhere around 145.275MHz FM simplex. | |
*A note about the frequency information for new amateur radio operators:
- FM – set your radio to FM mode (as opposed to AM, SSB CW etc).
- 123.345MHz – this is the frequency you will be using to listen to the repeater. It’s the frequency the repeater uses to send out transmissions that it receives from other operators.
- -600KHz – this tells you the relative frequency that your transceiver will use to transmit. So, you’ll set your radio to this number (note the plus or minus character), and when you transmit, your radio will switch to the relative frequency. For example: if you’re listening on 145.6125MHz and the relative number is -600KHz, when you PTT (push to talk) your radio will switch frequency down to 145.0125MHz, switching back to the original “listening” frequency when you release the PTT button.
- Analogue voice – this repeater is for analogue voice transmissions (rather than digital or other means).
- CTCSS – this is a number you’ll enter into your transceiver for the CTCSS or “tone code” (or similar name). When required by the repeater owner, CTCSS (Continuous Tone-Coded Squelch System) is a process that adds a tone to your transmission that the repeater will be listening for. There are various uses for CTCSS, but in this example, if the incorrect (or no) tone is used, the repeater will ignore you; no one will hear you transmitting through the repeater.Example: CTCSS tones are not actually below the range of human hearing but are poorly reproduced by most communications-grade speakers and are filtered out before being sent to the speaker or headphone. Go to this online tone generator and play a tone of 440Hz (the note an oboe plays for orchestra members to tune their instruments). You’ll hear a note. But if you change the tone to 72Hz (the closest to 71.9Hz used as a CTCSS tone) you’ll hear nothing or a very low tone (depending on your speakers).

THURSDAY 21st NOVEMBER, 2024 @ 2030 (local time) we’ll try a 6m experiment again.
Details here: https://fparc.uk/2024/11/20/experimental-6m-net-io90/
THURSDAY EVENING 14TH NOVEMBER 2024 – at the end of the 2m Net (approx 2030 local time) Graham M0CYX will bring the net to a close, and then QSY to 51.530MHz (6m) FM/vertical as a comms test.
If that frequency is in use, we’ll congregate on the FM Calling Frequency (51.510MHz) to figure out what we do next.
Hope to catch you on either event 📡
Not got a 6m antenna? Tim G5TM shows how to “whip” one up (🤦♂️) using a little math and a telescopic antenna upon a car roof magmount.

Evening from Tim in Gosport. Foundation exam tomorrow so hopefully will be able to talk on air next week.
Good luck, Tim 🤞
I’ll be running the net this evening 3rd October from 1930 local time.
We’ll start on GB3CW and move to GB3SH if necessary. If that doesn’t work then simplex on 145.275MHz. Chris G3WIE
I’m in the chair again this evening. We’ll start on GB3CW and move to GB3SH if necessary. If that doesn’t work them simplex on 145.275MHz. Chris G3WIE
OUR USUAL NET CONTROLLER will be away until after 9th October. The Club is a little short of available resources at the moment, so there may not be a stand-in NC until short notice. Do listen in to GB3CW and if there’s no NC Call, please feel free to jump in and Net together. We’ll update this as new information is available.
