Jacky – I worked with the Noise/Com company a while back to get several NC302L diodes to build Bill Sabin's homebrew noise sources without having to meet the minimum purchase requirement as they have been obliging to hams. It took several phone calls and had to work with a sales rep but I prevailed and posted the following to the emrfd Yahoo group….whether this is still valid or not I'm not sure but worth a try. Here's what I found out:
"Guys -- I was just notified that Noisecom has approved waiving the $250 minimum order and will sell the NC302L noise diodes in small quantities to hams. Just placed an order for a couple; they are $28 a piece.
You can order from Noisecom by calling:
(973) 386-9696 and then choose "1" and "1" at the two prompts to get to Carolyn in the sales department. Let her know you're a ham and she'll be glad to help. They take credit cards.
I'm not sure if the calibration offer is still available but hopefully the offer made a couple of years ago is still valid.
Anyway, nice people to work with....tell them you appreciate them making an exception for us....goodwill always goes a long way!"
Additionally, they MAY still be doing calibration for hams as well….at least as of July 2008 according to Gary WB9JPS back in 2008:

Some good news: Noise Com is calibrating sources again (as least for US customers). This is from an email forwarded to me by Bill Sabin:
As you are well aware, in business terms 1994 was a long time ago. Noise/Com to this day continues to offer Amateur Radio Experimenters discounts on diodes. Calibrations of these Noise Sources have been more a factor of available resources. After review of your request, on a trial basis we will resume our offer to calibrate these noise sources at a substantial discount. Pricing will need be $100.00, turn around time will be a function of available resources and will most likely be quoted at 8 - 12 weeks. This will be for domestic customers only, as we have had too many issues with noise sources being held up in customs. Customers will need to contact Noise/Com for an RMA (Return Merchandise Authorization).
