I’m thinking about starting a Tilt for the $750 option – 10 shields. It comes out to $75 a shield, which is $25 cheaper than getting just the shield.
Who’d be interested? I want to get two.
Looks interesting. I don’t see how something like this can be useful without shielding the Arduino though. I wonder how much work they’ve done on noise? (don’t have time to read right now).
I would be interested in one at least.
Yeah, no shielding cans (shown, anyway) and from the board design I don’t think there is much RF filtering, certainly not bandpass filters for all 3 bands. I’d be concerned about harmonics from high-power signals (eg. broadcast FM, pager, possibly Arduino clock) really harming the receive performance, similar to RTLSDR, since these are all going to be close to the intended bands and require fairly high Q filters. Though I suspect that most applications for this are going to be heavily biased toward TX.
Inclusion of 1.25m band is interesting. This fairly wide band sits mostly unused and with little equipment available. With SDR-based transceivers such as the module they use on this board becoming the norm though I think this might change.
There’s already a quite similar board, based on the same SoC, available, at a slightly better price: https://www.hobbypcb.com/products/rs-uv3
There are also SA818 modules for like $10, with more output power, if you don’t need the multi-band capability and can build some simple filters to control the output. I think I’ll pick up a couple of these, which I didn’t know about until looking into this KS. Been working on an APRS tracker for years, but the radio interface part is such a pain…
I like the Arduino shield just because it cuts down on what I need to know in order to get up and working. Maybe once I’ve got a project or two under my belt I’ll look into the RS-UV3 or the SA818.
Just 2 days left for the HamShield. Everyone now gets antenna + PSU bundled for free PLUS they have now confirmed a free upgraded power amplifier.
Sean, There’s a 4 HamShield bundle for US$330 or $82.50 each. You want 2 and I think Paul wants one and I’d go for one too.

I already backed the project, I’m getting two boards.
Sorry, I got impatient.
