Resource Page

The purpose of this site is to be a repository for links and information related to the digital ham radio modes and related software that are being used by an informally associated group of hams in the Midcoast Maine area. If you are not a ham, find a local club. They welcome new members and most will provide tutoring and exam sessions. Becoming a ham has never been easier or more interesting.

Nets and Local Services

 

Sunday Maine NBEMS VHF Net

7:00 PM on the KQ1L Linked System. This net is a continuation of the Midcoast NBEMS Net that has met since 2010 on the Waldo County W1EMA repeater. The format is voice check ins followed by digital traffic. Recently we have been focusing on using Flmsg and Flamp. The preferred mode is PSK125RC5 (5 carrier PSK125R) centered at 1500 Hz on the waterfall.

Participants are invited to prepare Flmsg files (bulletins, messages, csv format spreadsheets) using ICS or any other included format. Radiograms may also be submitted by using the Flmsg ARRL form. These will be submitted to NTS via NTSD or the voice Seagull Net.

Hams who are new to NBEMS are welcome to participate. It's a training net and we are all very supportive and patient.

Please visit the NBEMS page for detailed information on Fldigi, Flmsg, Flamp and Flwrap.

Please direct any questions to KB1TCE (email address at the bottom of this page).



Washington County Emergency Training Net

This net is sponsored by the Poverty Hill Amateur Radio Group and will cover emergency communications and public service support. The net includes the use of NBEMS. The net meets on the first Thursday of the month at 6:30 PM local time on 146.565 MHz FM.


Maine HF NBEMS Net

The Maine HF NBEMS Net has resumed operation as of October 2013 with KB1UTD as NCS. The net meets every Wednesday at 7:30 PM local time. Frequency is 3583.0 MHz USB +1000 Hz. Initial mode is Olivia 8/500. More information may be found on the Maine HF NBEMS Net page.


KB1TCE-1 APRS is not transmitting local weather at this time. Repairs to the wind instruments are pending.


Owl's Head BBS and Winlink RMS

A packet BBS/RMS is now in operation at Owl's Head. This has been set up expressly for Maine ARES. More information may be found on the Owls Head BBS-RMS page.

APRS - Automatic Packet Reporting System

There is quite a bit of VHF APRS activity in Maine. Uses include search & rescue, resource tracking, weather reporting and messaging.

VHF APRS

"Mr. APRS," WB4APR Bob Bruninga's APRS site has much of what you need to know about APRS including the many options for sending messages through the APRS network.

SK Roger Barker's UI-View is still the standard software for APRS. Visit the official UI-View Page for details on the program and installation. UI-View seems to work with Windows 7 but eventually it will be obsolete as the code no longer exists and updates are not possible.

Stephen Smith's WA8LMF APRS Page is also a tremendous resource for APRS. He probably has the best guide for setting up UI-View for use with Undertow Software's Precision Mapping.

A great introduction to APRS is contained in K9DCI's APRS Beginners Guide 2010.

If you feel that UI-View is getting a bit long in the tooth or are looking for an APRS program that's optimized for SAR, check out SARTrack. It seems to be quickly displacing UI-View in these parts.

EasyPal

EasyPal is a digital SSTV program that has been developed by Erik VK4AES. The software uses DRM (Digital Radio Mondiale) encoding to allow the sending of image files over HF or VHF using only a bandwidth of 2.5Khz, equivalent to voice). Compared to analog SSTV, the transmitted digital images are of outstanding clarity. The mode uses error correction and incomplete transmissions that fail to decode may be "fixed" by the program's ability to request the missing blocks from the sender. EasyPal can also be used to transmit text files. Downloads may be obtained from VK3EVL's EasyPal Site. Help files and older versions are also there.

EasyPal is an image mode and primary activity in the USA is on 14.233 USB, 7.173 LSB and 3.723 LSB. The Midcoast VHF Net also works with EasyPal on a regular basis.

The image below was transmitted by KB1UTD and received at my station.
