Picking up NOAA imagery is mostly a feat of constructing a good antenna than having a high bandwidth, or great clock. Thus, for reception only, build a nice helical antenna, and any cheap RTL Dongle, as long as it works at 1.698 GHz – if you don't want to waste the signal quality you've earned through the antenna, a cheap LNA (Lna4all seems to be nice) will help. That'll cost you very little.
Regarding working at 1.698 GHz: The Osmocom RTL-SDR wiki page has a list of RTL dongle integrated tuners and the frequencies they reach. If in doupt, the rtl-sdr.com store dongle comes in a nice metal case and has the R820 tuner that works up to those frequencies
Now, for NOAA you need no TX; so, we can't tell any TX spec requirements from your question. All answers to your question would thus be based on guesses, and personal preferences! So, write down proper specs, and ask a new question about TX-capable SDRs. You'll want to specify:
- The range of center frequencies you want to cover
- The instantaneous bandwidth you'd like
- Ideally, a Noise Figure requirement; but that's hard for a beginner to guess, so instead,
- Describe what you want to do with that SDR, in more detail than "transmit":
- Transmit and Receive what kind of signals
- How weak are these signals, or from how far do they come, or what is your plan to do with these signals?
Point is that an SDR is really just an universal device: It lets you capture the radio signals "as they are on the air", and calculate the signal to be put on the air in your computer. So, an SDR doesn't serve a single purpose that we can guess from the start – you'll need to find out what you want to do, and then we'll be able to help you :)
