Over all, this series of videos on the features and use of those features is the best on the net. I've had my 7300 almost a year now and by far is the best transceiver I have had yet. that included the K3. Your explanations are clear, you show examples. 73's
CW DX stations often send QRZ up and they are expecting you to call them 1 to maybe 5 KHZ up from the frequency they are transmitting on. This is essentially split operation but the delta TX way to operate split is probably a little bit quicker than using both VFOs and maybe easier to set fine granularity of a few KHZ.
This video gets real honest at 3:15. I was thinking the same thing. I use RIT regularly, and it’s simple and effective. I disagree on the manual Notch filter though. I prefer to have the control of it because everyone’s ears are different.
Monitor: I set this feature ON. all the time, because, I am listening using IEms/earphones. This feature is very useful, durring data mode. So we can hear and make sure if our PC/laptop sends correct signal modulation during TX. Thank you.
When I call CQ and a person answers me slightly off frequency, I want to keep my transmit frequency the same but I want to offset my receiver to his/her transmit frequency. Otherwise as you know I would be retuning throughout the QSO to what I want to hear, and so would he, and hence we would both be chasing each other either up or down the band. So, in that situation I use the RIT feature. But, when I want to contact someone (DX or contest pileup station) who is already in contact with someone one else who is slightly off their frequency, I want to keep my receive frequency on the DX or contest pileup station's transmit frequency, but I want the DX or contest pileup station to hear me on the same frequency as the last contact that he made. That is, I want to offset my transmit frequency (not my receive frequency). That's when, I use the "Delta Tx" feature. Yes, I could do it the other way around. That is, I could retune to the "someone else" and then use the RIT to hear the DX or contest pileup station, but it seems to me more intuitive and it is certainly more convenient to use the "Delta Tx" feature in that situation. I never had a rig before that provided a "Delta Tx" feature, but when I got my 7300 I immediately fell in love with the feature. It made me think, "Now that makes sense. Indeed, very smart. Why haven't my previous rigs had that capability?"
I think the monitor is essential with headphone. I noticed my signal as (xxxx) with the monitor on. The power meter showed spurts of power. With another mike everyting fine. Headset went back to Heil. I too think they wasted a button on the delta TX but thanks for explaining what it does. I am a lazy ham. 73
I see a use for it when trying to work DX who are working split, particularly on CW, when the splits are typically 1-3kHz. The manual seems to indicate that XFC can be used to monitor what's on the TX frequency, which can be handy for seeing where the current station being worked is, to help you set your own split frequency.
Hi Ben. Yes, it would work for that and the XFC button will allow you to hear what's on the transmit frequency. I've had a couple other comments from people who work CW that use delta-TX. I don't do a lot of CW work, so I missed that use case. Thanks for the comment and pointing it out. 73, Tom
The video has some age on it, but a real use for this is working CW pile-ups when you are hunting/chasing. By moving your TX around, you do 2 useful things: 1) you move away from the pile, so your signal isn't exactly on tope of the others in the fray and 2) change the audio frequency a bit which may make your sound more distinctive for the runner. Both of these help the Runner/DX station pull your signal out of the pile.
I use the Delta Tx somethings on Cw contesting. When responding to a CQ with many others on same frequency, I respond a few hundred hertz up or down. Can make the contact that way.
@@HamRadioA2Z I do this on CW and also SSB. Sometimes I can hear the other guy best at some specific frequency relative to the other noise or QRM, and then adjust my TX slightly up or down so that my voice stands out from the crowd. I try various TX settings until I get through.
where the RIT function allows you to hear a TX that drifts a tad off frequency, allowing you to TX at the selected try, the Delta TX (∆TX) allows you to TX allowing for drift in your own tx frequency. So if you're talking and he says you're drifting -900 Hz, you can adjust +900 hz so you effectively cancel the drift, while you still hear at the selected frq
setting for 5 up or 5 down using ΔTX leaves the other VFO for another band frequency if you would like to use VFO A/B button. In split mode, both VFO are used and you cannot use it on another band frequency. It is also quick to adjust the offset with the ΔTX
Thanks for you response... yes the headset is plugged into the audio jack on the front of the radio. I would think that should mute the speaker on the top of the radio. I don't think headset i have uses the pin 8 output. Could it be picking it audio via induction??? The cables run together into the heil adapter from the headset. Really enjoying your tutorials...
Well Dave. I’m afraid I’m stumped. Yes, plugging the headset in the front will mute the speaker. That will be very apparent to you if you plug it in with the radio on. I suppose it could be crosstalk in the headset wiring, but Heil is pretty good about using high quality shielded cables. So that seems unlikely. An experiment you could try is to plug a different headset into the headset jack while using the Heil headset microphone. If the feedback goes away, that would be a pretty strong indication that it is something in the headset wiring. You might also try calling Heil customer service to see if they have any ideas. I have heard that their customer service is pretty good.
When using headsets in a recording studio the same thing may occur if the headset volume is turned up very high. OR if the mic gain is turned up for some reason the same thing may occur. From K5WAW Bill W
Note: If we set RIT or XIT/delta TX, and using logging apps on PC/laptop, the application only 'see' the frequency on display. Example: If the frequency on display is 7.130 MHz, and we set RIT or XIT to 5 kHz, logger application will record the frequency on the display.. in this example, 7.130 MHz, not 7.135 MHz. Thank you.
Thanks for your tutorials! I have just gotten my 7300 and your talks have been great. One question on the Monitor function... I use a single earpiece Heil Pro-micro headset. I usually run the monitor at 8%, which isn't really loud enough for me, but if I run it much higher, I start to get feedback. Is that normal or do I have to use a different headset with both ears covered?
Hi Dave. I wouldn't expect feedback issues when using a headset. I can't think of any reason that a single ear model would be any worse in this regard. How does the headset connect to the radio? Specifically, where is the earpiece getting audio from? Does the headset plug into the mic connector and into the headset jack on the front of the radio? Or, does it just connect to the mic connector? The 7300 has audio out available on pin 8 of the microphone connector. If your headset is getting speaker audio from there, then the speaker won't be muted and you could be getting feedback from that. With the headset audio in your ear, you might not notice the speaker is still on. If the heil doesn't have a separate plug going into the headset jack on the front of the radio, then try plugging another headset into that jack and see if the problem goes away. If that fixes the problem, you'll need to get a dummy headset plug with nothing wired to it to plug into the headset jack. That will still disconnect the internal speaker. If that's not the problem, then I'm not really sure what else to suggest.
I would assume delta dx is for working rare stations who are listening 5 to 10 kHz up in frequency in order to split all the stations calling so that they can be picked out. It's a shortcut for the A / B VFO functions normally used to do this. Commonly used operating style for Dxpeditions etc.
Yes that’s a good example, but a lot of times, I’ve heard DX stations listening way more than 10khz up and then you can’t use the Delta-TX. Myself, I’d probably just use Split regardless. However, as I just said in another comment, this radio has enough options and ways to do things that everyone can find a method that is comfortable for them. There’s no right (or wrong) answer.
Delta TX: Generally I use it, to TX during 'net' which the net operator asked to TX at certain frequency, example '5 up' .. where the operator is monitoring/listening. So, the Delta TX is more easier, because we only need to set the delta TX to 5 kHz. Example: Net operator TX at 7.130 MHz. He is RX at 5 up = 71.35 MHz. So, we set our rig's VFO to 7.130 MHz, and set delta TX to 5 kHz. Our TX will be at 7.135 MHz. We can check or monitor using XFC button, to listen and check the VFO. This feature is similar to RIT, but in reverse. Set our rig VFO to 7.135 MHz, and set RIT to -5 kHz. and we now RX/listening to 7.130 MHz .. but the VFO is stay at 7.135 MHz. So, generally sometimes it is much easier to use delta TX at certain condition. Thank you.
Hopefully you still monitor this thread! I have been watching these videos on the 7300 and am learning so much, thanks for making these! My question is, the monitor feature doesn't seem to do anything on my radio. I turn it on and it doesn't do any of the things you are getting it to do. I also noticed that if I go to the monitor setting from the Multi button, I cannot turn it on and off by tapping the monitor button. Can you help me out on that?
Hmmm. Off hand I can’t think why the menu touch screen button wouldn’t work. Out traveling right now. I’ll check the manual and play with mine when I get home and see if I come up with anything.
I noticed that my monitor function stopped working for an unknown reason, but when I pushed the multi button to bring up the menu selections, and then hold the "monitor" (at the bottom) it then lights up "MONI" at the upper right of the main screen (next to the time). Then the monitor function worked again. You can touch the "MONI" at the upper right and it will change back to "M-CH" or "kHz" whichever you had before. I have no idea why the monitor functions stopped working or why this seems to reset it.
To make it simpler.. RIT is an offset of currnt RX frequency. Example, now we are RX ad 7.130 MHz. and the frequency display is 71.30 MHz. If we set RIT to -5 kHz, we are now listening/RX at 7.125 MHz, but frequency display stil at 7.130 MHz. Now, switch off the RIT. and set delta TX or XIT, to 5 kHz. Now, we are transmitting at 7.135 kHz.. Now, what will happen if I switch on the RIT? In other word, both RIT and delta TX is enabled. :) The answer is.. even the current frequency display is at 7.130 MHz, but, we are RX/listening at 7.125 MHz and TX/trinsmit at 7.135 MHz. Now, add split feature in this example. :) Hope this is useful. Yours, Bahathir 9W2GNU, 73.

Monitor Function:
I use a powered external speaker and adjust the Monitor level so I can hear when I am using Voice TX at a proper volume.
Thanks for sharing.
A word of caution, when my 7300s transmit level is set at 0 it still transmit at 5 to 7 watts on SSB.
Thanks for the heads up. I’ll have to check into that.
Same with mine. My power meter shows about 4W when set to 0 (AM/FM).
Dummy load is a good solution to this.

Late to the party, but as a reminder the delta TX only shifts 9.99 KHz either direction. Good for small shift, useless for greater shift.

I would have a dummy load on it! You have it set to 0 power but it does put out about 5 watts.

delta tx for working split
Hi, lil Pal.
To make it simpler..
RIT is an offset of currnt RX frequency.
Example, now we are RX ad 7.130 MHz. and the frequency display is 71.30 MHz.
If we set RIT to -5 kHz, we are now listening/RX at 7.125 MHz, but frequency display stil at 7.130 MHz.
Now, switch off the RIT. and set delta TX or XIT, to 5 kHz. Now, we are transmitting at 7.135 kHz..
Now, what will happen if I switch on the RIT? In other word, both RIT and delta TX is enabled. :)
The answer is.. even the current frequency display is at 7.130 MHz, but, we are RX/listening at 7.125 MHz and TX/trinsmit at 7.135 MHz.
Now, add split feature in this example. :)
Hope this is useful.
Yours,
Bahathir 9W2GNU, 73.
I never understood the reason for TX change either. If I wanna' work split, there are far easier ways to accomplish that.
RF POWER when 0 you have about 2 watts of power out!
You are correct. I learned that 0 isn’t actually 0. So I now make sure the frequency is not in use or I use a dummy load.
I don't think I will ever use it
I have a looooot of problem becouse of this funkicone!!!
