This request is for a feature that would (I think) be primarily of use during pileup situations during DXpeditions. So Q65 PILEUP makes it the logical place for it. As I have been suggesting for years, it would be EXTREMELY HELPFUL and make DXpedition operations so much more productive, if there could be an indicator when a station is receiving during the last receive sequence. When multiple stations are calling at the same time (especially during common moonset windows), a lot of time can be wasted by cycling through the list of all the callers and trying to reply to each one to see if there happens to be any reciprocal propagation with any of them. By the time one tries responding to 10 or 12 callers, plus delays in running out to aim the antenna, considerable valuable common moon time has been used up :-( I don't profess to have any idea how the system works, but here are my suggestions from a DXpeditioner's point of view: 1. In Q65 PILEUP, apparently there is some way to transmit "R" with the callsigns and grid TX3) and for that information to be received by the other station. 2. If a station could optionally turn on the feature, perhaps they could send an * (or some other symbol or letter or number) when they receive a yellow spike (perhaps with some adjustable threshold above the background noise) during their previous reception period. 3. The DXpedition station could receive the new TX3 message with the * (or whatever instead of the R), and know that he could reply with a standard TX3 message and have it received by that caller. Of course, reception of that * message should not engage the AUTO SEQUENCE. If the caller stops receiving a yellow spike, the program would go back to automatically sending TX2. The HUGE advantage would be that the DXpedition station would be able to identify stations that have the capability for a reciprocal contact! Today, for example, I spent a lot time replying to a number of different stations who never received any decodes from me at all when I tried to reply to them :-( MNI TNX for your kind consideration!

Hi Lance I'll leave it others to comment on the first part of your request It seems from your last point that you suffer a lot from 'blind calling'. This was a real problem during the early days of Superfox mode, and was overcome by code that prevents a 'hound' from transmitting at all until they have managed to decode the signal from the fox. The code for this exists already, and could perhaps be applied to Q65 pileup at some point if you felt this would at least partially alleviate your problem. In the meantime, perhaps you could ask your followers to just adopt the discipline of not calling you unless they have decoded you first, in everybody's interest. 73 Charlie DL3WDG On Tue, 19 Aug 2025 at 00:08, Lance Collister, W7GJ via wsjt-devel < wsj...@li...> wrote: > This request is for a feature that would (I think) be primarily of use > during pileup situations during DXpeditions.

Hi Charles, To understand Lance's request, you must understand his operating conditions. He does 6M moon-bounce Dxpeditions to remote places, which requires very low noise, high power, and big antennas. To minimize his need for power, which translates to minimizing the cost of buying and transporting fuel over oceans, and then to remote locations where there's no noise, he INVITES blind callers. This is a method of operation he devised years ago. He's currently somewhere in the South Pacific, don't remember where. This is his website. https://www.bigskyspaces.com/ Scroll down to see his instructions to callers. I would encourage the development team to take his request seriously and do your best to accommodate it. 73, Jim K9YC |

Hello Charlie et al,
Yes, I invite "blind callers" for the following two reasons:
1. I need their calls to be decoded to populate the Q65 PILEUP ACTIVE
STATIONS LIST ("ASL") and provide the added sensitivity when it comes
time to participate in a contact exchange with them.
2. Due to the nature of Faraday Rotation on VHF EME, there may appear to
be "one way propagation" for extended periods of time. If people waited
until they copied me before calling, I may have lost the opportunity for
a complete Faraday Rotation cycle to receive them and add them to the
ASL. Since many of the callers are horizon-only stations utilizing
narrow ground gain antenna lobes, there are by nature very limited
windows during which to complete with them; having them delay the start
of the contact until they decode me further reduces the available time
for a contact exchange to take place.
I am sure you can appreciate the huge difference between this type of
weak signal contact and the essentially instantaneous strong signal
reciprocal contacts on HF using Fox/Hound or Superfox. On VHF EME, it
is quite an advantage to be able to determine which station(s) to engage
in a QSO that might be able to provide a quick reciprocal type of
contact. Currently, the only way to do this (without resorting to the
internet to have people report "I am decoding you now", which
essentially makes the contact invalid) is to try to work through the
pile of callers, replying to each in turn to see which ones may be
capable of completing a quick "reciprocal" type of contact with you.
Thanks to the ASL, it may be that some of the callers to whom you reply
may actually receive your message, although you won't know it until you
receive "RRR" from them at some later time. However, the best success
rates involve choosing the proper QSO partners with which you have the
highest probability of making a quick reciprocal contact thinning out
the number of callers.
It struck me that the Q65 PILEUP mode may finally actually provide the
means to transmit this information! I thought that there might be room
for this information the way the R report is inserted in TX3. I wonder
if the program could automatically send a message in place of TX2, but
similar to TX2 except with some other character (perhaps just a dash
instead of a space) to indicate that the station copied a yellow spike
during the receive cycle immediately preceding their transmit cycle.
This would be in place of TX2, and would revert to the standard TX2 if
no such yellow spike were received. It would not affect the AUTO
SEQUENCE of either station (other than the current action upon receipt
of a TX2 message) but would simply be displayed as a received message.
But it would be a sign to the DXpedition (or other) station to "please
select me next because I am copying your trace". I suspect that the
activation of this feature should be manually turned on by the callers,
although I guess it wouldn't hurt to have it running all the time
(unless it would add significant processing to the computers on one or
both ends).
Perhaps there are significant impediments that would make something like
this impractical. However, after hours of trying to answer callers one
at a time who don't copy at the time you tried them, I think it would be
a tremendous improvement if it were in any way possible!
Thank you for your kind consideration, and for the HUGE advance that Q65
PILEUP provides. It is already the standard on 6m EME! VY 73, Lance

Hi Lance
I understand your reason for wanting blind callers. I had not quite
understood your comment at the end of your first email, but all is now
clear thanks.
We used to use a somewhat similar scheme when Rex VK7MO was touring
Australia with a small dish on 10GHz, The interested stations were
allocated a single tone frequency beforehand, As soon as someone had
decoded Rex, they would transmit a single tone and that would tell Rex who
was copying him, and he would then call them, or call them next. I think
we got up to about 6 stations in the end with this scheme. With GPS locked
systems and CFOM Doppler control it worked well.

Hello Lance and Charlie, Unfortunately, that message or all standard messages support the 'R' using a single bit and there is no easy way to add another bit for that message. On the other hand, the field that conveys the report, grid or any of 'RRR', 'RR73', '73' and 'space' have available some unused bit combinations. If the grid is important for the QSO one possibility is to allocate a value that is presented to the user as '*' or any text. That new message could indicate that the station has *not* received the yellow spike in the immediately preceding slot. Or we could have even more values: 'BLIND ONLY', 'THREE OR MORE CYCLES AGO', TWO CYCLES AGO' and 'ONE CYCLE AGO' or something similar. The previous cycle would be indicated by the use of the grid i.e. normal Tx2. That method may not be best. if you need the grid value in the list for any transmission or reception purposes. In the case EME it may not be so important as it will be there once you want to contact that station. Whatever it is a program update, I leave it to the designers. 73, Reino OH3mA |

Hi Reino, MNI TNX for the background. No, we need the grid for the contact exchange. So the message would have to be TX2 PLUS some other indicator such as a hyphen (-) between the calls and the grid. I was hoping this could be done instead of the R, but I understand that apparently there is not enough available bits to send - instead of R 🙁 It is only valuable to know if a trace was copied (yellow spike received) during the immediately preceding sequence...

Thanks everyone for all the information. It appears that the only way to implement this feature would be to do a second decode with the inverse of the timing sequence, the way Joe did with JT65. That sure would be a great feature for Q65 Pileup!!! TNX and VY 73, Lance On 19 Aug 2025 22:11, Lance Collister, W7GJ wrote: > Hi Reino, > > MNI TNX for the background.
