Re: 3.5" inch TFT LCD Module 480x320 For arduino uno R3 mega2560 board
Yes, it does have an SD socket. I do use it on the antenna analyzer project, as it allows up to 9000 scans to be saved and later downloaded in CSV format. That format can be used to import the data into graphics programs, spreadsheets, etc. It works well and is easy to code. The Arduino SD library is all that is needed.

Jack, I was looking at the 2.4" display you mentioned, and it looks as if it has an SD card socket on the back. Is that the case? If so, is it usable?

Almost finished, for now...
Just got the case finished and am happy with the results. So far I've burned my finger, pinched my palm with pliers, smoked a pot (10-turn), and blew through 3 fuses trying to measure voltage. On the other hand: - Raduino v1.09 successfully compiled and loaded
- Got front firing speaker/phones port working nicely
- Will be adding push button function, line in and PTT for digital, keyer jack
- Still need to wire the LEDs on the front for Rx and Tx
- Will calibrate once the push button is in
Still have a couple of questions though. - When checking the PA-Power, do I connect the VOM to the +/brown lead and the -/black lead or do I attach the negative to the Power ground?
- Do I still need a calibrate switch with v1.09?
- I'll be using the Bourns 10 turn pot, I know the pins are different than the single turn but in what order do I connect them? Purple on back, blue in middle, yellow in front? The only way that somewhat worked before the pot died was purple, yellow, blue but the freq went the opposite direction of the pot turning.
- For line in and PTT, can I just connect them to the respective lines coming off of the handset adapter? Or is there a better way to hook those up? My thought is to splice the 2 positive PTT wires (from handset and jack on back) together to go the PTT brown wire, and the 2 negatives to the PTT black wire. Would do the same for the mic and line in wires to the mic port. Seems simple enough to work.
Thanks for everyone's help so far! It's been a long while since I've actually used my EE knowledge and it's slowly coming back, just not all of it... 73, Brian, K2BRZ

Re: shipping options, raduino, source code and website updates
Hi Michael
I have never paid any custom charges if shipped via mail. I've never shipped by courier except from Digikey, so can't comment on that.
If you order from outside Canada, ask the shipper/seller to mark package as "Amateur Radio Parts" or "Amateur Radio Kit". This will move the package through customs faster. Amateur Radio 'stuff' is duty/customs free up to a certain amount.

Hi Phil,
glad you managed to load the software successfully!
You're nearly there. Just follow the operating instructions at

Re: New Telecommunications Reg in India
This is a a little confusingly posted. Let me explain the background...?
A couple of radio hams from bombay and calcutta noticed that the ham frequencies were being used by others. Investigations revealed that frequency squatters weren't licensed to use these or any frequencies at all. They were using the cheap Baufeng handsets that could be ordered online from aliexpress and . They were being used by logistics and event managers.
Subsequently, the WPC issued a notice to these websites to stop selling these transceivers to non-hams in India. So, in a nutshell, here is the crux:
1. The notification is to not export any transceivers into india without a valid license copy. This is an iteration of our existing rules. The websites were asked to verify the license of the purchaser before selling them Amatuer frequency equipment.
HF Signals does not sell VHF/UHF transceivers. It sells kits. There is no restriction on selling any kits or components that maybe used to make wireless equipment. Indeed, this is the very thing that Govt of India's Department of Science and Technology has been trying to promote for years.
On our end, we verify that the boards are only shipped to those who have a valid license. We do this by cross checking the call-sign of the purchaser on to match with the shipping address. In case, they don't we ask them to confirm the different address.
I personally believe that there are easier ways for people to communicate securely across the international borders than using the BITX. It is difficult to work any station consistently as it. You'd think that any head of SPECTRE would actually rely on a BITX board to take over the world? They will pick up their samsung and call with Telegram?

Re: Raduino_v1.04 allowing 10-turn tuning pot for complete band coverage
Quick answer: Yes I'd put a 0.1uF cap on both ends of the tuning pot wire. ? One at the tuning pot and another at the Raduino end. ?Both are from signal to ground. ?Any RF picked up in that tuning signal wire can cause random jumps in VFO frequency.

Re: New Telecommunications Reg in India
From the article: ?"our concern is that the powerful equipment can fall into wrong hands and be misused. More importantly, these two-way radios can tune into any frequency including confidential frequencies used by law enforcement agencies. They can be misused to listen to confidential wireless conversations" That cat has long since left the bag if lawful confidential wireless conversations are carried out in the clear on narrow band FM rigs. ?I agree that random individuals with 5 watts of RF can make communications difficult for authorized users of the spectrum, perhaps that is the primary beef of the amateur community there. ?And then they add this argument about receiving law enforcement communications because they know it will strike a chord with the powers that be. ? Alternately somebody selling amateur equipment doesn't like having to compete with ebay, if so these arguments may well be turned on the Bitx40. ?In which case we all pitch in to buy Farhan an airline ticket to Bolivia.
