Mike, this was why I asked this question - so there is a good reason for having this feature.
I like however Frank's suggestion of making it configurable. It's just software... :-) 73!

It may be a nuisance in general operating but | its a must for weak signal microwaves as well as DXing. If its a problem | for mixed mode, its because everyone has differnt radios or set ups are | different. If everyone had CWU and USB or CWL and LSB then it would | normally alway be ok. | | A perfect example was yesterday afternoon. 6 Meters was open to the east | coast to the Caribbean, but here in the midwest, the DX was coming in very | weakly and had lots of QSB. I spent considerable time watching a station | and calling him on SSB. Most guys were calling on SSB, a few were calling | on CW. The ones calling on CW were not being responded to by the DX. Why | you ask? Did the DX not want to work cw? Nope, all the CW was outside of | the SSB passband. Easy to see on the SDR-1000 bandscope. It was obvious | that the DX was not even hearing the CW. These were stations with rigs | that did not have the CW freq offset function when switching between SSB to | CW. i.e. you would have to retune in order to hear it. | | With no luck on SSB, I gave one call on CW. DXCC #77 on 6M! He came back | to me on SSB without retuning to hear my signal. We worked cross mode with | no effort. I just laughed when I saw other guys again calling on CW, just | outside of the lower end of the SSB passband...I tuned away know that the | funtion does what it is intended to do. | | A few other rigs do it correctly. Typically the Yaesus do just fine. The | Icoms did not until the Pro II I believe, and then yet you had to set it up | that way. They would have CW on the LSB side when you were on a band that | utilized USB. | | Other examples from the microwaves and weak signal work, we would try to | work on SSB and say the signals QSBed out. You knew the guy was there, so | we typically switch to CW. The guys with yaesus driving their transverters | or whatever would pop out right where you needed them to be without tuning. | I can recall many times loosing guys who I knew were running Icom 706s, | etc. The fact of retuning to find a weak signal was normally a loss of a | possible contact. | | This is why I ran Yaesu radios for my VHF and microwaves | IFs....er...uh.....until the SDR-1000 came along of course :) | | Again, my 2 cents. | | 73 | | Mike - KM0T | | | ----- Original Message ----- | From: "Bernhard Hailer, DL4MHK/AE6YN" <[EMAIL PROTECTED]> | To: "FlexRadio" <FlexRadio@flex-radio.biz> | Sent: Saturday, July 14, 2007 10:16 PM | Subject: [Flexradio] Frequency for CW and SSB | | > Hello, | > | > question regarding PowerSDR: when you switch from USB to CWU, PowerSDR | > adds | > the side tone frequency to the currently used frequency; e.g. you operate | > USB | > at 21.4000 MHz and your side tone is 600 Hz, your new frequency is | > 21.4006 once you switch to CW. | > | > This may be logical, but it is a nuisance if you operate mixed mode: I'm | > practicing CW with some local hams here, and I have always to correct the | > frequency when we have a final SSB chat after our practicing. | > | > Is there a purpose behind this scheme?
