SDR Voice Keyer for Mac

Update April 10, 2019: Now that SmartSDR 3.0 has been released I most likely will have to do an update to the program. I have not upgraded yet as I have a couple of other programs I use that will not work with 3.0. The Voice keyer may work if you are not using multiFlex. I expect to update the Voice Keyer within the next couple of weeks when Doug K3TZR gets the framework I use updated.

A voice keyer for the Apple Mac is now available for download. The SDR Voice Keyer can run on the Mac with dogparkSDR or FlexRadio SmartSDR running in a virtual PC or even on another Mac or Microsoft Windows PC on the same network. You do not need xDax or xCat as SDR Voice Keyer handles all audio and control functions on its own.

Operation is quite simple. Make sure the DAX button on the SmartSDR P/CW panel is on or in the case of dogparkSDR select TX DAX in Preferences -> Radio -> TX DAX .

Click the button you want or on the keyboard use ⌘1…⌘0 for buttons 1 – 10 (if the SDR Voice Keyer has focus). The radio will be keyed and the audio transmitted. The Stop button or Esc will immediately stop any current transmission. You can adjust the Transmit Gain if necessary using the slider.

If you want to be reminded when to send your ID, check the ID Timer checkbox and a green flashing graphic will appear in front of the Send button. Click the Send button (or ⌘S) and your ID file will be sent.

Touch bar support is included if you have one of the newer MacBook Pro’s with a Touch Bar.

Getting ready for VK0EK – Heard Island

This is a busy DX year. Lots of ATNOs to be had. For me it has been VP8STI and VP8SGI, I had already worked Palmyra back in 2005. The next ATNO for me will be VK0EK Heard Island. The VP8s have been difficult and I expect VK0EK to be even more difficult. I managed one 40 meter QSO with VP8STI and a 30 meter QSO with VP8SGI. Last night I was trying to work VP8SGI on 20 meters CW. The QSB was really bad and there were a couple of times I thought he may have come back to me but he was very week. Then finally I was sure I had him, I sent 5NN TU and then… some idiot decided to transmit right on top of VP8SGI. By the time the LID had finished he was working another call. So what to do, keep calling and hope I got through again or wait until the log is uploaded in a day or so. If they were using DXA as VK0EK will be I would have known within a minute or two that I was in the log. Then I could have felt great or started trying again. You can see a demo of DXA or read a more detailed article about DXA.

Quest for FT5ZM

New DX on the air today. Amsterdam Island, FT5ZM showed up on the air this morning.

I had stayed up late last night trying to work some new ones during the CQ WW 160 meter contest. I only have a short vertical for 160 so it’s tough and I have to maximize the contests. Overall I did ok, three new ones, Jamaica, Cayman Islands and Korea.

Recent DX Activity

It has been pretty busy lately, Wake Island, Banaba Island, American Samoa, Myanmar, Bangladesh, Lakshadweep and more. Here on the west coast K9W was pretty easy. I worked them on all HF bands and even managed a QSO on 160 meters.

T33A Banaba Island Update

T33A has only been active a couple of days and I haven’t had much time to work them yet. Interestingly, I worked them on 10 meters the first day they were on. Quite easily too. Usually the “Big Guns” are squeezing me out of the pileups, got lucky, maybe they were asleep 🙂 Then this morning I worked them on 30 meters after trying for quite awhile.
