The best antenna? that I have used are antennas that are large loops. The signal strength is comparable to a dipole but the noise floor is lowered 10db approximately. Our previous loop was 1300' and seemed to have the best signal both on transmit and receive.
Our current loop is 2600' It performs excellent on 160 and 80m but rolls off above that. Most signals sound like they are vhf FM.?

This is our draft of a Double-Double Mag Loop, which was just published in
Rad Com. Note how it results in much higher efficiencies.

Vic, I took a look at your setup, nice.? The case you are using is the same I have on order for my V6.? Any issues with it and did you use the 3D face-plate
or cut your own out?? I intend to try cutting my own but will fall back on the 'ready made' if all else fails.? Glad your loop works well, the commercial model I tried must have been defective because I could never get the SWRs out of the red!

Re: Which I2C address does the 320x240 TFT display on the v6 use?
Gordon,
If you are looking at using a board with the Bosch BMP180 transducer the I2C address is 0x77.

I received my V6 in 7 days after ordering it. That was about a week ago. Just got it working and I would definitely order one ASAP to avoid being put on a waiting list.

I don't know the specifics in India right now, but I understand the 'kits' are assembled by contract workers who pickup parts, take them home, assemble them, then return them to be tested and shipped to buyers. Based on that understanding
and given the current situation in India, it's possible that HF Signals is currently shipping product, but at best I would expect their volume to be greatly reduced.
Were I in your situation, I would order the radio and simply wait for it to ship - by ordering now, you'll get your radio as soon as possible - if you wait until the situation in India 'normalizes' you will be placed at the end of the queue
that built up between now and then.
That you aren't seeing a response to your email suggests things are, at least, running slow/behind.
Hope that helps,
Ken, N2VIP

Re: Okay last time questions and then i quit
Hi Rene, I think David may be correct.? Before you have said:
 Rene
I use 3x 18650 in serie with a 78h12....so 12volts and max 5A. Now? glued 2 battery paks together and have 6x 18650. I get the18650 from old bike battery's. At the moment i have 60 of them, so power enough?? At a high discharge current, Li-Ion batteries show about 3.7V each (and that's only on a near top charge battery).? So 3 x 3.7V is only 11.1 volts.? Then you have a 78h12 on it which even more messes with the voltage supply because the battery voltage drops below the level needed for it to function.? Note:  Your rig may run OK wit the same battery pack if you just take out the regulator.? But even a 4 series pack may not always provide enough voltage overhead for the 12V regulator you have: 3.7V * 4 =? 14.8V 14.8V - 2.3V(typical dropout for your regulator)? =? 12.5V Once the pack starts to discharge you will drop below this and run into trouble again.? Of course a 5 series pack should be just fine (with some good heatsink on the regulator). 73, Mark

Yah, I'd like to tell you my forfathers ?invented the Beverage antenna. ?I've investigated that but turned up little info on it's origination. ?I did have one when I was a kid building my own one tube receivers so I could lay awake at night listening to baseball games in far away places. ?I was a farm boy with lots of acreage and that antenna was probably 80 yards or so long. ?It was a simple antenna for a kid requiring no poles, hangars or much else. ?I just laid it on the ground along a fence line.

Just received mine by DHL a few days ago --no problem even here in Los Angeles county.? Of course things may have changed in India, in the last week.? Hope this information is still current.? Dave Casler was enthusiastic:?
Of course he ordered it earlier.

Re: Okay last time questions and then i quit
Hi Rene
I have not see this suggestion given to you before so here goes.? Have you checked the power supply you are using, you need at least 3 to 4 amps for transmit, it is your power supply is going into current limiting and partly shutting down giving the noise.
If your power supply is OK remember that you could remove the power from the final PA FET's to protect them while you test, you should still be able to hear the signal from the transmit driver on you monitor receiver.
Hope that helps

When using version 1.110 on my v6 modified?with Nextion and CEC version 1.200 I had the same error.
I did find however if I left the unit off and only connected the usb connection then it all worked fine - I could also turn on the 12v supply at that point and it still continued to work.

Re: Which I2C address does the 320x240 TFT display on the v6 use?
Gordon, The I2C is brought out on a connector (similar to the ubitx wire connectors). It has 5 pins : GND,?+3.3v, 5V, A5, A4. You can connect any I2C device to it. More in an hour?or so. - f

Re: Which I2C address does the 320x240 TFT display on the v6 use?
Consider his code:
XPT2046_Touchscreen ts(CS_PIN);
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);
The ILI9341 is usually associated with SPI interfaces, so doesn't use a slave address.
