I can't wait to try this board. When I'm ready to buy do I just pay through PayPal to the email supplied by Jack with number of boards I want and mailing address?

Francesca,?
My apologies. You were a 11 to 31 for signal report. I could hear u ok at times. Just couldn't hear you well when it counted. Hahaha. Wasn't sure if u were hearing me OK. Next time we will make it work

On 7.277 I worked AG7HX, KF7SEY, WA7SDI. Heard W7LTG. Could not pull off the QSO with him.?
Then I changed frequency and had contacts with W7JCV, KE7ZAC, KG7M. Heard W6LVW but I was in his noise.?

If the IRF-510 is blown will the radio output anything at all?
First use I know everything was working and it was moving my SWR/Power meter.
Second use, I upgraded my power supply to a 12v 3.5amp. Little to nothing moving.
Switched back, still the same.
I was assuming the IRF-510 was blown since that seems to be the easiest thing to do with these.
But I can still see my ssb voice modulation (now weakly) on my sdr which is in the same room.
Is there anyway my (cheaper rtl-sdr) SDR is picking up something from the radio anyway? If what I said is even the problem?

Re: BITX QSO Night, Sunday, August 13, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
I started calling CQ BITX on 7.277 about 6:45p local time.? At times, I heard a loud, strange?"squealing" on frequency; thought maybe a station trying to call that had problems.? I then continued to call an just before 7:00p, Keven, KN4AAG (NC) ?called and we made contact.? Then I heard Keven making QSO's so I just listened to him as he was hearing and working stations that I was not hearing.? I went QRT at about 7:30p.? I am looking forward to next Sunday!? 73, de Karl, KO8S (MI).

Re: ADAPTER BOARD - REDUX
For information on a feedback approach for leveling the output of an AD9850/AD9851, see the AD603 data sheet and particularly the example discussed on p 18 of that document. ?The output of a DDS decreases with increasing frequency due to both the low-pass filter and the sin(x)/x characteristic of the discrete sin wave construction.

Re: Potmeter value for tuning
Hi,
Thanks guy's I changed the potmeter and it work great with Allard's version 1.20.1!!
No more fiddling to change frequency.

Re: BITX QSO Night, Sunday, August 13, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
Everyone was weak until just before 9pm, when a few stations came through stronger, try calling later in the evening.

Thanks for letting me know. Now I wonder which antenna I was using at the time.

Re: BITX QSO Night, Sunday, August 13, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
Hey John...sorry to hear that. Can you hear anything on 40m ? Maybe try just a random long piece of wire into the bitx for rx test only. Maybe find a small 12v battery and take the rig outside to the yard or a park. I assume you have antenna restriction where you are so anything inside will be compromised especially on 40m. Perhaps find a small tuner or build an easy L MATCH for an end fed wire ? There has got to be something you can do. Email me if you more info. By the way, almost all signals are really weak on QRP - that's normal. Gotta call CQ man! I usually have a pipeline down to NJ so if you want to try a sched some night drop me a line .

This is one of the issues with LM386. In my first board, whenever the volume was turned down the chip
produced a buzzing noise.
I feel that the wiper lead should have anything from 1K to 10K in series. This does not affect the volume.
With a resistor there is no instability.

Re: BITX QSO Night, Sunday, August 13, 7pm Local Time, 7277 kHz in North America, 7177 kHz elsewhere
Great night:
Heard and or worked:
NX2U, VE6PG, KC4LRR, WC8WBK, W1LY, KG0BK, AA5TN, Heard other
stations, some rag chewing
and qsb took them out before I could make contact.
I'm running 5 watts to an inverted V up 50' on tower.

Such a fun radio !
Worked N8DAH, W0OIC, KC8WBK, AF1U and KB0BK.
Heard others but some QSB and lightning crashes at my QTH again
this evening.
Will try again next week.

Re: VU2ESE AGC Schematic redrawn
I added the VU2ESE AGC to my BITX40, along with a bypass switch. It does work, but as I found in another post, I need more audio out with the AGC engaged. The poster recommended replacing the 1uF capacitor at C113 (LM386 pins 1 to 8) with a 10uF cap. I intend to try that. Has anyone here made that change? Any other mods to this AGC that would be helpful?
