I have a scanner capable of HF receive, multiple HF receivers, and several HF SDR transceivers capable of receiving on more than one amateur band slice simultaneously. Lots of contest stations run more than one receiver at a time to "pounce" on whoever pops up on any of several bands. When using a radio with a scanner, or a station with multiple ...

It may have served a purpose in the past, with less filtering in transmitters and receivers, no digital frequency displays &c, e.g. to avoid mistaking a harmonic on a higher band for the transmitted signal.

Apart from historical reasons it's also a filler. When calling CQ on SSB you probably want to stretch out your transmission a bit because that's what you need to get heard. In theory you could just say your Callsign and "CQ", as it is enough information. If people would hear each call immediately it would suffice. In practise expanding the length ...

There are a couple of options. If your phone supports WiFi calling and your provider allows it, I strongly recommend getting WiFi in the shack if you don’t have it already. If you don’t have it, and that’s because you’re remote, get a LTE<->WiFi router with SMA connectors and an appropriate antenna. If you can’t use this solution you can buy cell phone ...

The question asked: I've heard a lot of CQ calls from other hams on [HF] phone, and it seems that a large portion of hams routinely mentions the band being called on within the call itself. Henry Flower's answer to this is correct. Here is additional, historical information about "CQ 40" etc. Before new laws were passed —in the mid-20th century— ...

We can come up with any number of reasons, perhaps historical or utilitarian, which aren't invalid. But I think the primary reason is saying nothing but "CQ" more than six times leads to an uncomfortable self-reflection on the sound of one's voice. So naturally as humans we want to add some other words, the band being one of a very small number of ...

Though this may seem somewhat counter-intuitive at first, I think it is also worth pointing out that certain call signs are better understood when the letters are pronounced together instead of the drawn out phonetic pronunciation of those letters. Of course this may depend highly upon the noise inherent in the band conditions. But I often find that many DX ...
