I believe the tuner memories remember settings for each antenna, so you are correct.

Thank you for the comment. The logging program is called Logic, from a company called PDA. The URL is www.hosenose.com

Hi Rod, The Logging software that contains the software keyer is Logic Version 10: www.hosenose.com The software that displays the LCD screen of the K4 is called OBS Studio. I connect an HDMI cable between the rig and an HDMI to USB converter that plugs into a USB port on my computer. Then OBS Studio can display the screen image from the converter. obsproject.com/ www.amazon.com/gp/product/B08QF6YWWD/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&th=1 The wattmeter display comes from the Virtual Control Panel for my Telepost LP-100A wattmeter. This software is available from the manufacturer. www.telepostinc.com/LP-100-Update.html The two monitor programs for the KPA500 amplifier and KAT500 tuner are ones that I wrote. I have a couple of videos about them. They were written in a language called BBC BASIC for SDL. www.bbcbasic.co.uk/bbcsdl/index.html 73, Mike - WB4HUC

Thanks Mike! I enjoy your videos and started watching when you were doing Ten Tec etc. I still have an Orion II. 73 Rod

Thank you for showing this I use different software and ethernet to control my radio but USB keying is nice for contesting.

Maybe. I'd have to give it a try to be sure. I wasn't trying to display an exhaustive use of the built-in PSK31 feature, I just wanted to show an example of how it could work. 73.

I'm glad to hear it is working for you. Did you have to use OmniRig? For some reason, the Win4Icomsuite software required Omnirig in order to work with the SDRUno software.

The exchange between two stations in FT8 seems to be pretty rigid, both in content and timing (the 15-second transmit and receive cycles). I would suppose there would be a need to account for those things somewhere in a setup menu or something. But you could always email Elecraft and ask them if it could be done in a future firmware update. 73,Mike - WB4HUC

I can tell you how I have mine, and I do have some things for you to check. Check to make sure you are using the correct version of OmniRig. There are two versions. One lets you set up two radios for OmniRig and the other lets you set up 4 radios. Use the two-radio version. In Win4IcomSuite, I have COM21 for SDRUno, COM23 for WSJT-X, and COM26 for N3FJP. In OmniRig, I have set up Rig1 for the IC-7300, and I use COM11. COM 11/21 are the virtual serial port pair for SDRUno. In the SDRUno MAIN window, click the SETT. button at the top of the screen then click the ORIG tab in the Main Settings window. Check that either Rig1 or Rig2 shows the Rig Type as 7300 and RIG status as on-Line. In the SDRUno RX CONTROL window, click the SETT. button at the top of the screen then click the ORIG tab. Select RIG1 or RIG2, whichever is assigned to the IC-7300. Then make sure these checkboxes are selected: SYNC VRX --> RIG, SYNC RIG --> VRX, and SYNC RX MODE. SYNC CENTER FREQ. (LO) should be unchecked. Close the RX Settings window. In the RX CONTROL window, either RSYN1 or RSYN2 should be showing at the top of the screen, depending upon which one you selected in the RX Settings Window. Click the RSYN button to activate it. After that, as far as I know, SDRUNO and Win4IcomSuite should be communicating with each other.

@@wb4huc10 Thats hoe I have it set up. As long as I change bands with the buttons on the SDR Uno screen everything works great. Thanks for the help. Thanks. Bob, W1RPQ

@@wanderingwithbob2472 Ok, I have one more idea. I was going to ask if you could change bands from the IC-7300, or only change frequencies within a band using the radio. it sounds like you cannot change bands on the radio then have SDRUno follow. If this is the case, check one more thing. In the SDRUno MAIN window, make sure that LO LOCK is NOT selected. If LO LOCK is selected, then the behaviour is that you can turn the VFO knob on the radio to change frequencies within a band, but if you try to use the rig to change to another band SDRUno will not follow. When you deselect the LO LOCK feature, then SDRUno will follow the rig when you change bands using the rig. Or, It should follow the rig. let me know how it goes.

@@wb4huc10 That was it now i can change bands from the radio, Win4ICOM and SDRPlay. Thanks. Knew it had to be something simple.

@@wanderingwithbob2472 I'm glad you got it working. Since the panadapter display is provided by separate hardware and software from the IC-7300. it is necessary to learn to use SDRUno as well as Win4IcomSuite. There's a bit of a steep learning curve with SDRUno, but it might be worth it to read through the manual. Good luck.

SDRUno is designed to be used with the SDRPLAY RSP series of devices. So yes, you need one of the RSP receivers connected to the computer so that SDRUno can see it. Once you have SDRUno working with the RSP device, now you need to feed a signal into the RSP device through the antenna jack on the device. The signal into the RSP device comes from the 7300. This means you need a way to feed a signal from the IC-7300 into the RSP device. I use something called the PTRX7300. This is a circuit board that fits inside the IC-7300 and provides an antenna connector so that the antenna jack on the RSP device can be connected to the IC-7300. The PTRX7300 also protects the RSP device from damage while the 7300 is transmitting. One disadvantage of the PTRX7300 is price. It is expensive. There are other ways to do this. One way is to use something called the MFJ-1708SDR. This allows you to connect the IC-7300 (or other transceiver) and the RSP device to the same antenna at the same time. There are relays inside the device to switch things so that the RSP device is protected while the IC-7300 is transmitting. There are TH-cam videos on both of these devices and I recommend that you watch some of them. After everything is connected properly, then you can configure Win4IcomSuite to talk to SDRUno. This allows you to point and click on sigals in the SDRUno panadadapter and the IC-7300 will be tuned to that frequency. And when you tune the IC-7300 using the VFO knob, you can watch as SDRUno also tunes the RSP device to follow the IC-7300. So basically what you get is two receivers (the RSP device and the IC-7300) listening to the same frequency using the same antenna. But they are tuned simultaneously through the softwware (SDRUno and Win4IcomSuite Plus OmniRig) communicating with each other. I hope that makes things a little more clear. 73, Mike - WB4HUC

@@wb4huc10 Yrs, that cleared things up...and then some. Thank you very, very much Mile. I really appreciate the indepth reply. The information you provided is the first thorough "What, why, and how" summary on the topic I read/watched all day!

@@msgaltman3075 I'm glad I could help. 73.

I have no experience with Com0Com, but perhaps the author of Win4yaesuSuite could help you. Good luck . -- Mike - WB4HUC

About 6 years too late I know, sorry. Just picked up this unit at a hamfest and had to figure it out. It will turn on with 12-14V DC but you won’t get any audio through the unit doing that. It needs 12Vac or maybe a pinch more. Bit odd for amateur gear but I guess the signal chain needs bipolar supplies. I did modify mine with a small switcher to invert and make -7V so as to feed the 7905, then changed to a regular 5.5x2.1 barrel jack on the back, so as to allow regular 14Vdc.

@@supton1532 Good and helpful comment post. So on the back of this filter, the input power jack is not labeled, and requires at least 12 VAC? Interesting and odd! I am looking for one as I sort of collect audio filters for use with simpler receivers to use on CW. They are fun to use. Thanks and 73, Jack
