saveSource: https://cdn.shopifycdn.net/s/files/1/0597/9668/4956/files/TX2501_240111.pdf — Grid from the TX2501 manual's Frequency Table (TX2501_240111.pdf, one page); band names as the maker's own Betaflight file prints them (https://cdn.shopify.com/s/files/1/0597/9668/4956/files/TX2500_TX2501_vtx_table_25mw_2500mw_ch_ABEFRLX_230601.json, linked from the TX2501 page). The file and the manual agree on 55 of 56 cells: the file prints B5 as 5999 inside a ladder reading 5790, 5809, 5828, the manual 5809. Power: the manual, the product page and the file's own name state 25/800/1600/2500 mW; the file labels its four levels 025 / 1.2 / 2.0 / 2.5 with values 1-4. The manual calls the control IRC (Tramp), where Betaflight sends milliwatts, so the values stored are the manual's mW figures. The manual also prints an X-band output curve (1 W at 4990 MHz rising to 2.5 W at 5200 MHz) that no table slot carries. The CNC page sells the same TX2501 in a CNC case: same text, same 56CH 4990-5945 and the same 25/800/1600/2500 ladder.

Where this data comes from
Read 2026-09-25 off the brand's own shop, the fifteenth VTX manufacturer catalogue read beside the US retail scrape. www.skyzonefpv.com and atomrc.com are two Shopify stores of one company: /products.json?limit=250 is the whole catalogue in one request on each, the two shops carry the same product_type taxonomy and each lists the other brand's transmitters, and the boards are silkscreened with the brand whose name is on the case rather than the one in the page title. The CNC-case version of the TX2501, with fan. Its own page states '25/800/1600/2500mW adjustable power output', 'MMCX Antenna connector' and 'Allow use customized frequency 1Mhz by 1 Mhz from 4990~5945', which is where the tuning span here comes from; the 56 channels are the 7 bands of 8 the TX2501 manual prints. input_voltage is empty on a published page because the brand states it twice and differently: the page's feature list says '7-26V Wide Range Voltage input' and this model's own case, photographed on the VT5850 and VT6550 product pages and read at full resolution, is silkscreened '9-26V / GND / 5VOUT / GND / VTX / IRC' beside 'Tx2501 CNC 5.8G 2.5W VTX'. One statement against one publishes neither. The brand annotates this case 38.8 x 38.6 x 22.5 mm in one of the page's own photographs, which is a body and not a mounting pattern, so mount_mm stays empty. The listing 'SKYZONE TX2501 CNC VTX' at /products/skyzone-tx2501-cnc6-vtx is a second listing of this same radio at a different price ($75.00), not a second product: same text, same images, same 4990~5945 statement.
