for those with older SSB radios wishing to use selcall, there is now an iPhone/iPad app that will generate the codan type selcall.
Just search the app store using "selcall". I have no connection with the author of the software except for requesting him to add, which he kindly did.

Hi ho

Sounds great but can see one very big problem. You will need phone reception to use it and once you leave settled areas, that is one thing that you do not have.

No you don't....
The phone (or iPad) does not need reception to generate a Selcall.....

It really is only useful for those that want to press an older radio such a Codan 7727 into service, perhaps as a backup in an emergency.

Looks like you hold the HF mic to the iphone speaker to play the iphone-generated tone over the HF.

Hi

I thought that it must have used the phone network, so I am wrong, sorry. It must be an audio tone from the devise. My Codan 8525 does not have selcall, so it would be interesting to see how it goes.



Thanks for the heads up



Cheers

Yes, it will work well with that, just bear in mind that it only encodes, no decode.

Yup, can only send and not receive.
BUT, it can send your self ident with the selcall.

I carry a 6924 as a backup when travelling, so it will be handy to contact VKS or friends.

It sounds like the real deal. Will try a beacon call later tonight (after work).

From the VKS 737 site:

"One solution to not having selcall capability is to install a Jenal SC51 selcall into the radio, while this option is very successful it is also
fairly costly at around $700 including installation."

$700 fairly costly! Thats more than a radio costs. $2 for the app is looking good.

Confirm successful Beacon Call to Swan Hill. I turned the phone up to about 3/4 volume, and held it about 10 cm from the NGT handset.

I note the same developer has an app called HF Weather Fax. Amazing. Worth a separate entry I feel.

I've tried it a bit more and been able to raise beacons in Swan Hill, Adelaide and Alice Springs.

Thanks for alerting us to this app.

Thanks for posting this up. An interesting development.

Apologies if these are dumb questions, but I launched right in a paid my $3 to check this out, and now I want to know how it works....

I assume the Codan tone mode is what is used by mobile HF radios regardless of what 'brand' of transceiver you have. Is that right?

What does the Center frequency mean? What guidance would you provide regarding adjustment.

Is Call ID the selcall number set in the other radio/base you are calling, or your own selcall number? Likewise for Send ID?

It will work with any transceiver and mimics the tones generated by a selcall module in a late model unit.

Just leave the center frequency as is.

You enter your selcall ID and the one you are callling and hey presto, it works.

I tried it on the android version,. Neat app.
