Paul’s updated RF Exposure Calculator

Many thanks to Paul Evans (VP9KF), who writes:

Yes, after a couple of years of regulators trying to bring their new rules into effect, the new RF Exposure Calculator is available at:

http://hintlink.com/power_density.htm

v2.0 denotes that the new rules to be introduce on 2021-05-03 are included.

There are a number of follow-on documents yet to follow from FCC,ARRL, Ofcom and RSGB in order to fully correct the documents which have covered amateur radio ‘exemptions’ in the past. There are now no exemptions except for 0 dBm (1 mW) or less for ANY service under the FCC (not just the amateur radio service). The new rules both sides of the Atlantic are different but cover all RF emitters. The only not fully finalised are the wireless high power, low frequency chargers intended for electric vehicles (a daft, inefficient way to charge them).

If you have questions, use the Help page indicated (‘CHANGES’). This is still untidy because it has grown into coverage of USA, UK and EU regulations, including some that are not technically in effect until 2021-05-18 in the UK by Ofcom. EU transition, when you see how it’s already done, is a mess.

Multiple sources are not included. There are differing views on this subject, some of which may yet be amended and have certainly been over-complicated by the regulators.

The biggest thing to note is that in the USA and the UK practically all radio amateurs must now do an assessment of their RF Exposure levels with virtually NO exemptions. The UK rules are more onerous in some ways, with everything over 10 W requiring examination and with portable and mobile stations needing (somehow) to justify their results. Imagine being on a public hilltop with your transceiver for HF or 10 GHz?

Both sets of rules include exposure limits for technically trained professionals and for members of the ‘public’; with 6 minute and 30 minute power averaging. They assume that members of a ham’s household are ‘trained’. If somebody else wanders over your property, they are not.

The massive FCC document (169 pages) makes for hard reading and either contradicts itself in some places or leaves some questions un-answered. However, it is a ‘final’ document and not a draft and comes into force on 2021-05-03. If you have an existing station you can wait 2 years to comply by calculation. If you have a new station or you change anything, you need to comply by calculation after 2021-05-03. Put up a new dipole on 80 m? You’ll need to comply.

Move house? You’ll need to comply. Go out on Field Day? You’ll need to comply. How it gets policed by the FCC is anybody’s guess. In the UK, Ofcom can monitor your signals undercover and knock on your door and ask you to produce your calculations from 2021-05-18 onwards (no two year grace period!).

Enjoy your new 5G maniac induced RF Exposure regulations, even when a huge distance away in the RF spectrum.

Icom IC-705 delivery delayed

Please note this is a cross-post from our sister site, the SWLing Post.

Many thanks to SWLing Post contributor, Paul Evans, who writes:

As you’d expect, Icom has formally delayed the delivery schedule of the IC-705.

Here’s the announcement from Icom Japan: https://www.icom.co.jp/news/4720/

The following is a machine translation of the announcement:

“Thank you very much for your patronage of ICOM products.

We have received reservations from a large number of customers about the IC-705, a 10W walkie-talkie with HF~430MHz all-mode, which was scheduled to be released in late March 2020. Some of the parts involved in the production of the product are delayed due to the new coronavirus issue, and production has been delayed due to this.

We apologize for any inconvenience caused to all of you who are looking forward to our products.

As for the delivery of the product, because it is a situation in which the arrival schedule of the part does not stand now, I will guide it separately as soon as it turns out.

We will take a while to deliver it, but we will do our best to deliver it as soon as possible, so please understand us.”

Thanks for sharing this, Paul. No doubt, delays are due to the affects of Covid-19 on both manufacturing in Japan and throughout the IC-705 supply chain.

For updates, bookmark the tag IC-705.

CW Club lookup for logging programs

Many thanks to Paul Evans (W4/VP9KF) who writes:

If you’re using a logging program and you need instant look-up of who is in what CW Club, you can use the following page, which I look after:

CW Club Call History files: http://www.g4bki.com/club_call_history.htm

These files are kept up-to-date on a daily basis. You’ll see that this currently lists memberships of 69 different clubs, including the vast majority of QRP clubs, a surprisingly high number.

One exception: G-QRP [who] told various sites that used their (previously open) membership list to cease using it.

Thank you, Paul!
