I'm not sure how the 7.277 frequency was chosen for our Sunday night QSO parties since I'm an old VHF/UHF guy just getting into HF? and not familiar with how everything works down here, but the complaint of QRM from the broadcast stations has been an issue now for a few weeks (there was one on 7.275 last night).
Last night there was a net operating on 7.277 past 7PM EDT, so I proposed an alternate of 7.282 which was clear when I posted. I did manage to have a brief exchange with Tom, VE3THR? on that frequency. I stayed on there until 7:30 (when the Yankee game started; LOL) and didn't hear anyone else. I understand that later on, there was a QSO going on that frequency, so Jerry, W0PWE, tried 7.285 (not sure if you had any success there, Jerry).
Anyway, unless someone more familiar with 40 meter ops has a better idea, I would propose that we keep 7.277 as the primary frequency for now, but standardize on 7.282 and 7.285 as backup plan "A" and "B". I actually had one VFO set on 7.277 and the other on 7.282 last night so I could jump back and forth easily.
Please, I know there are a bunch of you who are regulars on Sunday night, so please give us your thoughts and let's come up with a plan we can all agree to so we're not scrambling at the last minute next week.?

There are a couple in?the US - I know that there is on on the west coast in or near San Francisco, and one in the East in Pennsylvania:

I also listened? last night but was clobbered by the broadcast station on 7275

I listened for a little while. After the net cleared outta 7.277 I heard
nothing there for the rest of the time I was listening. Never did hear
anything on the other two freqs mentioned. So I went back down to 7.074.

I really, really like WebSDR receiver site near San Francisco:?
?I¡¯ve been to the site and use it often. It has a massive HF antenna that is also used daily for receiving HF commercial airline traffic communications.?
It has many receivers on most Ham Bands.? Enjoy!

WEB Based SDR (Software Defined Receivers):
There are many more of these available on-line.? Just do a Google search for
"websdr" and select the one(s) that look interesting.? You can now find WEB SDR's
in almost every country.? They are quite interesting to use to verify your signal
propagation to various locations.? Also a good way to monitor the quality of your
own BITX transmissions.

I second this one. Excellent antenna and band range. This is the one I use to test my BitX and propagation from here in Oregon.

Thanks

John WA2FZW wrote... I proposed an alternate of 7.282 which was clear
when I posted... Unfortunately, I haven't been able to get on the radio at 7 pm for the last few Sundays. I always get an AM broadcast station on 7275 kHz later in the evening, and have experienced QRM on 7277 kHz the last few times I managed to show up. I have no idea why the extra 500 Hz, but the noon-time net uses 7283.5 kHz. Just a thought. I'll have to try and listen there in the evenings. -- 73 Keith VE7GDH

I checked 7285 several times Sunday night and it was mostly clear. That is a QRP frequency often used by SOTA and other groups. 73, AL

Something below 7200 pls ;-)

As VE3RRD pointed out, I have seen 7.285 posted as a QRP calling frequency in several places.? In my (admittedly limited) experience, there doesn't seem to be a ton of activity around there.? Maybe that should be the North America frequency?? It seems fitting.

As we all know there is on perfect frequency. I too have experienced QRM, SW broadcast and other difficulties on 7.277 but in general it is as good and probably better than what I have found tuning around.I have not found SW broadcast QRM to last very long at my QTH but of course your propagation is not the same as mine ? When I find 7.277 unusable I switch to BitX international at 7.177 but have found little action there. When I was beaming Europe I chose 7.177 and worked a few stations. It is good to remember that many countries do not permit operation above 7.2Mhz If trying to work DX I will use 7.177 +/-
7.277 was becoming known as a BitX net frequency and that will become better known with time. I have found BitXers on 7.277 during the week.,and usually start there on week days.
As with most nets, if the frequency is occupied or otherwise unusable the +/- rule works to find the nearest clear freq. but of course QRP power levels make this approach somewhat more difficult. I like the idea of a "go to" freq. like 7.285? but if 285 is busy I would go to 7.177 or resort to +/- Few antennas work well with a large frequency excursion and I will re-tune my matching network to achieve the best radiated power from our little radios if I have to move very far.?
Posting a usable Frequency to the group seems to work as does QRPspots and DXSummit postings, almost real time but we need to remember to check the internet.
Hope to work your BitX, Willy? ?W1LY

I haven't operated my bitx40 on 7277 for several Sunday evenings now because of the strong SW broadcast station on 7275. I don't have a notch filter to get rid of the 2KHz tone screaming out of my speaker. I have used my KX3 (with notch filter) to monitor 7277 at times, but notching a piece of audio at 2KHz does degrade intelligibility. So I haven't had much fun lately with my bitx40, back to using my KX3. Next Sunday if 7277 is unusable, I will try 7285 if it is clear and see how that goes (there is usually a net that occupies it until 7pm or so ET). Last Sunday I took a listen on 7282, but a broadcast station came up on 7280 and caused the same problem as with 7277.? 73 - AL

I have to agree with Al VE3RRD and Willy W1LY. I too here the wine on 7.277MHz even at my current location in Northern Ontario EN96. Nets are all over the place with guys running kw's just because they can. Since building our bitx40's i have become hooked on QRP. I orientate my wire ants to null the AM signals. My 66ft inverted L seems to work great. Tried a 40M inverted V dipole last week from Sudbury with good results. Mind you I am favouring north south propagation. ?Many non qrp stations during the daylight hrs can be had and most are surprised that i am only running ?5watts.?
So i propose we start at 277 and work up. Very little retuning required. From your QTH, tune ?upward to a clear spot and call CQ. YES pick up the mic and call anytime or day. So what if we use a few freqs. Word is getting out there about bitx'ers and the natives are getting restless!
Respectfully and 73 VE3THR
I'm still having fun!

I agree that there is too much QRM ?with the BC station close by as I commented a few weeks ago. Before picking a new one like 7282, why don't we check for a few weeks to make sure we don't run into the same problem again. Would a freq above 7.175 and below 7.200 be better to avoid broadcast traffic?
