Hi Guys! I have both versions of the board designed. Through hole with a size of 17X38 mm, single side. SMT with a size of 18X31 mm. SMT components are 0805. 1 uF cap is tantalum or niobium

Sign me up for 2 kits. 73, Alan N4AYE

Hello All I would be interested in getting 4 kits. 2 for myself and 2 for others in Calgary, Canada (since I know they are around) Thank You in Advance 73

I would order 2 kits, with parts. Prefer larger 1206 parts but 0805s are okay. -Jonathan

Thanks folks, great info... 73 de VE3EIT

Where is your project located?

Indeed, replacing the TDA2822 has solved the audio in my case. 73 franco

Hi Ken, the driving motivation here is for Single Side Band operations, with that said your totally and completely correct there is absolutely no financial benefit to building an FM only VHF circuit.

You are not alone. I would be glad to see a 6 meter or 2 meter or even dual band radio for AM or SSB or both. It would be easy to conceal from the HOA people. A small self

I understand the motivation, but the Chinese are mass-producing dual band HTs for less than $30 delivered to your door, and the Japanese are producing higher-quality units starting at about $120, how

I would be interested in either a board for either Size components , or a "kit" . Ron P

my attention has turned to building a single band rig for 2 meters and I am curious who might also be interested in such a device. my initial plan is to build the main circuit board the identical

Good to know. The discussion thus far is mostly about the LM7805 linear regulator on the Raduino. The TDA2822 and LM7805 set definite max and min voltages, but nobody really knows over what range of

My ubitx main board pulls about .6amp in transmit when the PA is fed from a separate power supply. tim ab0wr "Jerry Gaffke via Groups.Io" <jgaffke@...> wrote:

I made a board using a hobby knive. It is far larger than it needs to be. But it works *well*!. So put me down for 2 boards. Either 0805 or 1206 will work for me. tim ab0wr "Kees T"
