The TH-D74 is a handheld. When you see Kenwood naming, the H in TH is Handheld.. The M in TM is mobile.. -Mark

Since the group here is on the topic of VARA - can you explain where in the VARA software you adjust TXD? Kevin

If it's "not just audio" what other waveforms other than audio do you believe exist? Kevin

I'm not familiar with that radio. It's not a hand held is it. Paulbuchanan51@... KO4QWS

Hi, I have an old Kenwood TH-D74 and use it successfully with Packet Radio (Bluetooth connection) or Vara FM with a Digirig (but only in a slow mode) 73 Erwin

This is why I brought up the TH-F6 which is not purpose built for data. Though it does have a TNC setting in the settings menu for external TNCs. My setup for Vara FM on the go is : Windows 11 Surface

This has been done since the beginning of packet in the very early 1980s.? It's called a setting called TXD (TX Delay) and determines a delay between PTT and the beginning of the data tones. Usually

Hi Pedro, I think you will need to use virtual audio cable connections between the ZS-1 software and the Vara software. Mike KV4TT

It's not "just audio".? If the class-D amp doesn't switch cleanly or isn't switched at a high-enough frequency, it can/will produce a lot of IMD (Inter -Moduation Distortion. This doesn't affect

The Kenwood TH-D72 and D74 are the rare exceptions among hand helds in that they are actually purpose-built for data.? The RX-to-TX and TX-to-RX turnaround times are optimized for data to support the

In the DK8OK guide you will see you need some Virtual Com ports as well. More software to install..... AND, be sure to read Jose's Vara Quick Guide which you can access on the Vara Help tab. Page 10

The way this is written seems to generalize that all Class-D audio power amplification results in distortion.? While some Class-D audio amps are terrible - (and the ones in these portable radios

On the Zeus website, there is a link to a pdf document by DK8OK that gives detailed instructions on setting up for digital modes. https://www.ssb.de/en/sdr1/transceiver/zs-1-zeus-1-transceiver -- VY

I actually disagree. I have many HTs such as a th-d72, th-d74, th-f6a, and a ic Id-52a. All of which work just fine with either a digirig or a mobilinkd tnc3/4. All work with either the stock antenna,

Pedro, you might look at the manual pages 62-63. You need to add a Virtual Audio Cable software to your computer. Then you will find the audio channel on the PC. -- VY 73, Wes WB7BR

It is utterly unrealistic to use an under-powered handheld as a mobile for data, especially if you don't use a decent external gain antenna.?? Unlike voice, data requires a fully-quieted noise-free

Paul, I do not know of such.? I have seen a Kenwood TH-D74 do some Packet work, but this radio is out of production, and used units sell around $800, I doubt that is of interest to you.? Next closet

Thanks for your email. My end plan is to be able to do VARA FM mobile with a hand held radio and if I have to, use a portable antenna. Can you recommend a hand held that will work with a digirg VARA?

I have a Zeus ZS-1 that unlike Icom 7300 and others only has 1 USB connection that shows up as a com port. In vara modem setup I can only select the analog audio card of the PC that is not doing

Paul, As much as I like my Baofengs for voice work, from everything that I have learned over the past 5 years regarding doing Packet (and VARA), you should expect to be disappointed trying to do VARA
