After uploading the file to the radio I discovered that many of the simplex channels I previously used on my IC2820 were now gone (not surprising). Lucky I copied the original radio config to a new .icf file before I uploaded the new one.

One frustrating thing I did discovered with the 2820 cloning software is that the EXPORT function appears to only export the stations heard by the radio to CSV and no the full radio configuration. A full copy of the config can only be stored in the native .icf file format, which is full of numbers (looks like memory contents). So manually editing the config file was out of the question.

eg.

00001008C2169C000927C0564B32524453414C
001010564B3552574E2043564B3552574E2047
0020107220208101090000564B325244532041
00301008C2169C000927C0564B32524453434C

For those who have played with the software (CS-2820), you may have noticed that you can only spawn one instance. So copying the frequencies from my old config to the new config (the above link plus my original mapping) was not going to be as easy as I thought i.e export both and combine in notepad or excel.

I discovered that it is possible to highlight and copy multiple lines in the channel map (only in the application copy buffer, not in the windows clipboard – can’t copy it to excel or notepad). Once you have copied the lines you want from the original config select ‘File – Open’ from the menu and open the new config (in my case the above file – renamed). If the application has not been closed it is possible to place the cursor where you want to add the channels from the old config and select paste (control v) and the copied rows will then be placed into the new config.

I originally based my simplex frequencies (2m and 70cm) on the AREG frequencies in the modified ham Motorola Syntrx radios located on the AREG website.

	VK5 – 70cm Syntrx Frequency Plan – Issued 22/11/2005

The new updated file containing the new D-Star mapping, supplemented by my slightly modified AREG simplex channels can be located here.

Here is a screen print.

This is the .icf file converted to a .xls (csv to xls – from excel). The conversion can be done with CHIRP.

The Freq and channel file: 2820h

I hope this information helps someone.

Something I have been very wary about for some year had begun to be better understood over the last few years.

I remember a doctor from an Adelaide hospital who presented at an IEEE meeting saying “on the record there hasn’t been enough research performed to prove that electromagnetic radiation causes cancer, but off the record I have seen enough cases where I am convinces it does”.

This simple statement and other examples provided during the presentation really drove home that we must be wary and respectful when using an existing near electromagnetic emitting devices.

This article came from the local South Australia Amature Radio Experimentes Group Website – Thanks for allthe great work. See link http://www.areg.org.au/info/radhaz/radhaz.html

General Background Information

The question of Radhaz has to be considered when you are constructing an Amateur Radio station that will operate near members of the general public as well as your self.

The responsibility for ensuring that the operation of an Amateur Radio transmitting station is operating with in the ARPANSA and ACMA guidelines is souly the responsibility of the amateur radio operator in control of the radio transmitter.

As the standard for Radiation Protection Standard for Maximum Exposure Levels to Radiofrequency Fields – 3 kHz to 300 GHz changes from time to time. The information on this web site will become out of date. AREG accepts no responsibility for the information presented on this page, the relative orginsations should be consolted for the latest up to date information.

For complete appraisal of your situation, you should consult one of the many orginsations that are NATA certified.

As of March 1st 2003, the Australian Communications & Media Authority (ACMA) introduced new limits for human exposure to electromagnetic radiation (EMR) covering all mobile transmitters such as remote controlled toys, walkie-talkies and hand held two-way radios as well as radio communications installations such as broadcast towers and amateur radio stations.

Under the new regulations, mandatory limits are set by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and people who hold a licence for a radiocommunications facility will have to comply, and in certain cases, hold records demonstrating compliance with the limits.

For a complete details on the ARPANSA standard, please refer to the link below and the ARPANSA web site.

maximum-exposure-levels-to-radiofrequency-fields

The RPS No:3 Standard is known as, Radiation Protection Standard for Maximum Exposure Levels to Radiofrequency Fields â€” 3 kHz to 300 GHz (2002).

This Standard specifies limits of human exposure to radiofrequency (RF) fields in the frequency range 3 kHz to 300 GHz, to prevent adverse health effects. These limits are defined in terms of basic restrictions for exposure of all or a part of the human body. Relevant derived reference levels are also provided as a practical means of showing compliance with the basic restrictions. In particular, this Standard specifies the following:

(a) Basic restrictions for occupational exposure with corresponding derived reference levels as a function of frequency.

(b) Basic restrictions for general public exposure, with corresponding derived reference levels as a function of frequency.

(c) Equipment and usage parameters in order to assist in the determination of compliance with this Standard.
The limits specified in this Standard are intended to be used as a basis for planning work procedures, designing protective facilities, the assessment of the efficacy of protective measures and practices, and guidance on health surveillance

IDEAS page is all about putting up design and other general ideas. These may include part circuits or drawings of things that we have thought other people may be interested in. In general don’t expect a complete package, as this page is only meant to give you some ideas on what we have done. So you can further your own experimentation.
