Preferences - Bands - Frequencies: Band-Limits & Mode QRGs

Hi there,
I'm just wondering, what good the mode-limits will do for me, if entered in the frequencies table.
My assumption was, that if no TRX-Connection is present, the mode will be picked as a suggestion from the table, though offering the option to overwrite it.
This is apparently not the case, as the setting ist taken from the Preferences - New QSO defaults.

My current understanding is as follows:
The frequencies table specifies the *starting* frequency for the relevant mode. That would make e.g. the following values for 80m in Germany:

  • Begin (lower band limit): 3.500
  • End (upper band limit): 3.800
  • CW: 3.500
  • RTTY: 3.570
  • SSB: 3.620

So CW would be from 3.500 to 3.570, RTTY from 3.570 to 3.620, and SSB from 3.620 to 3.800 (not accounting form beacons and other digimodes).

If my understanding is correct, the question is, what good does this table to me if filled properly?

Thanks & 73

Preferences - Bands - Frequencies: Band-Limits & Mode QRGs

Hi!
At least when you double click DXCluster spot it sets right mode taken form mode qrg's.
But it is not so clear there either. There the "tmp" holds spot frequency as follows:

if (tmp <= cw) then
mode := 'CW'
else begin
if (tmp >= ssb) then
mode := 'SSB'
else
mode := 'RTTY';

So you see setting RTTY frequency really has no use there as check is done only against CW(upper) and SBB(lower) freq.
If you have no rig connection (rig would be moved to freq and mode set) usage is quite minimal.

Then band limits (not modes) are used in ADIF import https://github.com/ok2cqr/cqrlog/pull/282

Hi Saku,

Hi Saku,
so in other words, CQRLOG treats everything between "Begin" and "CW" as CW, everything between "SSB" and "End" as SSB and the bit in between "CW" and "SSB" as RTTY. - OK. So it's rather for my own reference to quickly lookup, if I don't have a bandplan at hand and no internet ...

Seems to me like old code that got lost somewhere in the development process ;-)

Hi Saku,

Hi Saku,
... me again.
There are 2 different QRG-tables in the preferences!

  • Preferences - Bands - Frequencies and
  • Preferences - TRX Control - Change default frequencies

... and they seem to be comletely unrelated. Moreover, what I'd expect is, that the latter is relevant for the case, that no TRX is connected via CAT ...
Well, interesting what you find, if you take some time to work through all the options ...
