Is anyone using the Palstar HF-Auto and DDDUtil? I followed the tutorial prepared by Dave WO2X, and downloaded the HF-Auto program, but cannot connect it to DDDUtil.

The setup box for HF-Auto in the "other" tab of DDDUtil is missing (I have the latest version of DDDUtil). I have searched the help pages for DDDUtil, but cannot find any reference to this issue.

Any ideas?

For those that are wondering, here is what I sent privately to Jay. This info should be a good troubleshooting guide to get DDUtil and the HF Auto working with the 6000 series radios.NOTE - When changing bands on the Flex it is necessary to move the VFO knob to get the radio to send out the FREQ info to DDDUtil. One of the quirks I found.

Here’s a few things to check first:

After installing DDUtil, make sure you select Signature Series for radio type. It should see the 6300 and in the title bar of the main DDUtil program it should show your operating frequency and mode.

In the Others tab of DDUtil you need to enter the actual LAN IP address of your PC (you can go to start/run and type CMD, then in that window type IPCONFIG. It will show you the LAN IP address (probably starting with 192.168. Type that address in the HF Auto area and also put port 12070 and check enable.

Now I use HF Auto app version since I do not need the extra features in, although you can use either version. There is a known issue with where it will sometimes crash with a .Net framework error. Terry has said the bug is there but he has not gotten time to address it yet.

You need a physical com port from your PC to the HF Auto tuner. It can be a port on the PC (built-in or a add on card) or a USB to serial adapter. I prefer not to use the adapter since it ***may*** be subject to RFI, although the RTS-03 that RT Systems sell are fine. In the HF Auto program change the view to 7 to see all the fields you need to modify. Towards the bottom half of the app you enter that serial port number (Under where it says Antenna) then click the disconnect button. It should go red and say connected. Now the app is talking to the tuner.

Next you need to modify the HF Auto config file in two areas the first area allows DDUtil to talk to the HF Auto app via UDP XML packets. Here is the section from my config


UDP_Broadcast=    ; UDP Broadcast Address / Port List

UDP_Receive=12040 12060 12020 12070 8000                    ; UDP Receive Port List (addr

USER.CAT_Source=DDUTIL                          ; Source Name in GUI for User Defined CAT Info

USER.XML_DocName=DDUTIL                   ; XML Document Name for User Defined CAT Info

USER.XML_FreqField=FREQ                         ; XML Field Name for User Defined CAT Frequency In


Notice I added 12070 as a port and changed USER.CAT_SOURCE and USER.XML_DocName to DDUTIL

Last, you need to edit the BANDS section to allow the HF Auto program to know how to operate. Since my Yagi is a 5 band Yagi and resonant on 10,12,15,17 & 20 meters  and I use a G5RV dipole for 30 meters and lower plus 6 meters mine is fairly simple. I defined three entries I called Low (1.830 to 13.9oo MHz), High 14.00 to 30.00 MHz) and 6m (49.9 to 54.0 MHz).

The Low and 6m are set to select the G5rv and put the tuner into AUTO mode (so it will tune).

The HIGH range is set to choose the Mosley TA-53M 5 band Yagi and puts the tuner into BYPASS mode since the antenna is resonant.

If you have multiple antennas and receive antennas for out of band, etc, this section can get complicated. If you are using only one antenna and want to have the tuner in circuit all the time then it is very easy. The key is the name for that entry, the start and end frequency, the mode of the tuner (AUTO or BYPASS) and a name for the entry (what shows up in HF Auto app.

Here is my entry for BANDS. Please note the punctuation between each field on each line. BTW, any line starting with ; is a comment line and no action is taken on that entry.


;               BANDS


; NOTE: These Rules are for Example Only - for W1TR Installation

; User Must Create Appropriate Rules for Their OWN Individual Installation



; Rules are Applied in the following order

; <Band>=<LowFreq>,<HighFreq>,<ANT>,<MODE>,<Antenna>

; NOTE: <Band> must be a unique identifier among all the rules





Last, you need to have the following checked in the HF Auto app.


This should be enough info to get you going.
