OK. That one should work. It looks like a Geeetech.com one. The important thing is that they use the Cypress chip as that it the one that is compatable with the AD drivers. Like the call sign! 73s

I will be attending the Scottish Microwave Round Table next weekend. As I'm flying up I will not be able to take many kits for sale in my carry-on luggage. Anyone going to the GMRT and wanting me to

Hi Brian....Disregard my earlier post. I believe I found the unit you reference at eBay item - 171052308693. Regards...Bill - N6GHz

Well done on the chip change. I recently bought three of these boards, one with an ADF4350 and two with ADF4351s. Perhaps I was lucky but all seemed to function as expected. Their PN performance is

Nice bit of wotk Neil ....!

I acquired an old DB6NT MK1 transverter and ext 2556 MHz LO chain for a local here in NZ there seems to be a number of mods to this board inc a small relay glued to the top board which seems to

I have an HP778D which works beautifully at 13cms, in fact it has good directivity up to 3.0GHz even though only specified to 2.0GHz. It is one of the most useful items that I own and when I

Hello Neil Probably not. Particularly above 1GHz, a length of flexible cable (unless it's an achingly expensive test cable with precision connectors) plus connectors is more likely than not to have

I can't speak for that particular item, but I have ordered from the RF shop before, and have sent numerous items back. Pins on N plugs or sockets protrude more than they should from the reference

Following a recommendation from Peter G3SMT, I bought a couple of 20dB 800-2700MHz directional couplers from The RF Shop and they seem to perform very well. On 23cm the directivity appears
