If *Winlink* or digital are main goals- a Rigblaster Advantage may be a perfect solution. Worry free, reliable, easy hook-up, working perfectly with years of constant use. No problems ever with any

Mike AE4ML, I have both the IC-7300 (Winlink Hybrid HF Station) and the FT-991A 'shack in a box' in my go kit.? If you are considering only HF operations the ICom option is my personal

It really matters where you are. High speed digital networks are great in urban areas. In south Texas we have Houston, San Antonio, and Austin as major metro areas and high speed networks are used. In

Stephen; You're right! ?I was responding to Steve in the context of Tadd KA2DEW's post (#6278), where he said " I’m partial to the Raspberry PI as a computing platform, but we’ll see how the

Being able to use existing VHF/UHF radios certainly has advantages, but they *are* voice radios, with audio bandwidths in the 6KHz - 7Khz range, when set for "9600bps data". With this limitation,

I just moved to Waynesville NC from western WA. In Western WA I participated in building/supporting the HamWAN network there, a robust high speed IP over 3GHz ham freqs that has instigated the build

I don't think Steve was suggesting compatibility with VARA. Just an alternative functional equivalent with certain suggested advantages. Stephen W9SK

NCPACKET is not so bad when you consider it in terms of a Maker-space hands-on? project.? The network has to follow procedures that are brought down to the level of the least-common ham.? While the

Hi Steve; I'm a Zero Retries subscriber... keep up the good work! I apparently overlooked the "Mercury software-defined modem" item. I checked out the git-hub site, and looked for other references on

Jim W8SNSI said: Jim; I’m not sure why you responded specifically to me. I haven’t posted anything on this topic that would indicate you’d have any issues with a TS-480SAT and SignaLink. Are you

Mark - AD7EF, I have used a Kenwood TS-480SAT with a Signalink and it has never given me any trouble. My computer is a Dell Latitude. There are two usb cords needed. One goes to the signalink (for

Mark: I wouldn’t abandon hope on such a system just yet. Check this sub-article in my newsletter Zero Retries -

Dick, If the VARA modem app is showing in the task bar, that implies that the session window started the VARA modem. Is the session window also showing in the task bar? If so, maybe it is off-screen.

In the open session window you need to select settings/radio to select the radio type.

Packet is using Carrier Sense Multiple Access, CSMA. (CDMA is Code Division Multiple Access, a form of spread spectrum) VARA HF or VARA FM is not CSMA system since the channel is reserved for one QSO

Tadd; As I pointed out recently on the VARA-MODEM groups.io "VARA on M1 Mac" topic: "The VARA HF and VARA FM radio-modem software is proprietary. It is entirely up to the developer, Jose Alberto Nieto

VARA HF sessions are the same. if there’s traffic on the channel, the operator trying to connect must click the “Connect Anyway” button. Additionally, if listening to radio speaker, you can

Dan; "listen for a clear frequency" isn't the same as "collision detect", in the context of CDMA. As I pointed out earlier on this topic; ... VARA FM supports the busy-channel detection that is

Not true. Packet incorporates CDMA, carrier detect multiple access.? It deals with collisions quite well. VARA FM, so far I know, does not listen for a clear frequency therefor does not detect

Correct. The two VARA endpoints use nearly 100% of the airtime, when in a connected state, exclusive of:* Key-up time on each transmission* Minor quiet times between keep alive transmissions during
