Re: W8TEE Release 1.06 of TFT/VFO code and 1.03 Assembly manual
Read the new manual and cut-and-paste the new material. The previous material is the same, but new material added towards the end. Reading side-by-side you can see what you might want to print.

Thanks, Vince. I am now out of boards, but have ordered more and they should be here in about 10 business days. Please write before ordering so I can confirm that the boards have been delivered.

W8TEE Release 1.06 of TFT/VFO code and 1.03 Assembly manual
All:
I have uploaded Release 1.06 of the TFT/VFO software and Release 1.03 of the assembly manual. For the most part, this release is bug fixes more than additional features of the program. There are some new details in the assembly manual. Please remember that you will beed to download MorseCode.h, too. It has not changed since the last versions. Both files must be in the same directory for the Arduino IDE to be able to compile and upload the code.

Q14's emitter resistor is the 10 ohms at R141.
It is not 100 ohms as I previously stated.

I'm definitely in for next week. I don't check this group daily so I missed out yesterday. PSK31 sounds good, it'll get my feet wet in it. So far I've only been doing FT8, JT65 and WSPR. -- Ryan Flowers W7RLF

Re: If the IRF-510 is blown will the radio output anything at all?
There's a few milliwatts of 7mhz going into the base of Q13. So Q13, Q14 or Q15 could be blown, and unless your rig is well shielded (doubtful) you will hear it on a nearby receiver. If you can press the PTT button and see 100ma (or much of anything) going into the PA +12v (into the IRF510 drain), ?then the IRF510 is probably ok. Q13 can blow if a nearby QRO transmitter injects a few volts of RF into the base, maybe add diode protection described below Q13 runs kind of hot, quiescent current causes it to dissipate more than the SOT23 package is rated for, maybe make it a 2n3904 in the TO92 package. Q14's emitter resistor is likewise running hot, maybe go to a 100 ohm 1/4 Watt resistor. You might check this post: ? /g/BITX20/message/23640for voltage readings through the transmit PA. Start with just the DC voltages (with PTT pressed). If it was a nearby transmitter blowing Q13, you might check this out on adding back to back diodes for protection: ? ?? /g/BITX20/message/30601The idea was originally from Raj: ? /g/BITX20/message/19105His incandescent bulb increases it's resistance drastically when it heats up, so is worth considering in addition to the diodes. /g/BITX20/message/21901I'd be suspicious of that new power supply, obviously. Perhaps it momentarily went to 20v when you first turned it on? That would be bad. Jerry, KE7ER

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?

Jack,
I sent payment for 2 boards. If you are out I am OK will waiting for them if that's fine with you.

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

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).

Hey John...sorry to hear that. Can you hear anything on 40m ?
Oh, it hears fine, and when conditions are good, I've worked some distant contacts. The radio itself works great! I did 80 contacts with it on Field Day. I've be using a hamstick dipole in the attic mounted about 4' above the foil backed insulation; not a great idea! LOL! I've been working on a 2 turn, 4' magnetic loop, and last night was the first test. Just had it sitting in the middle of the living room though. Not quite ready to move it to the attic yet as I still have some more hardware & software work to do on the Arduino controller.? No legal limits to more robust antennas, however I have a rather small lot and I'm getting too old to be climbing on the roof! If the loop doesn't improve things, I'll?build a vertical. ? -- John - WA2FZW
