MF SOLUTIONS Transmit Converter (FS)

23 April 18

STOCK STATUS: As of today, I have three (3) Kits and one (1) Built/Tested unit available for immediate shipping.  When those are gone, I’ll be taking the summer season off; see below!  Your support is always appreciated! CU On The Band!

EFFECTIVE IMMEDIATELY – The price for Built/Tested/Burned converters is INCREASED $5 to $100.  The KIT price is REDUCED from $75 to $70.  This is due to an overwhelming bias toward built units…I need to get out of the shop this summer and work on my antenna system!

If you want to get a jump on the 2018-19 Fall/Winter season, now might be the time.  I have several built/burned-in converters with the standard 3.2 MHz LO crystal and several kits ready to ship.  When this run of converters is sold I won’t be restocking until October ’18 at the earliest…                                                                                                    —————————————————————————————————————————————
